I have attempted many hole cuts and failed before I discovered your video. Great work. And I see why you need to turn over and 'break the seal' directly after scoring the circle. It stops any cris cross scores following through past the circle score line. Circle cuts are incredibly hard to master and you have made it look so easy.
Great instructional video, mate! Thanks to you, I was able to cut holes into two sheets of glass for a double glassed window to install a cat door! Greetings from Germany!
@@glassbeveller THIS is why my local glass suppliers had a series of glass circles {Rings} joined together! Clearly from cutting vent holes! I never knew how it was done. ..it was much thinner glass than this though.
Yes, I was also looking for an instruction as how to make a decent hole in the glass for a catdoor. This video was just what I needed to get a grasp at the possible issues that an inexperienced person will face when endeavouring the same result.
I have just tried to cut glas for the first time and understand now, that it is more complicated than you think. It's really fascinating how glass reacts to disturbances in the structure.
yes some neat tricks. I am Glazier myself it's nice to see some new tricks I will give that one a shot. there is a lot of people posting videos on how to cut glass and they say they have lots of videos on how to glass that are done by people that don't know what they are doing but this is very clever
great video thank you. We have only one glazier in town that will do it and it seems to be a mission for them and cant do it for weeks, Lame. Glad I watched this now I know to do two circles which is a great idea. Thank you again
Great video only constructive critism is I wouldn't say push hard . Unless a person knows what pressures you can and can't use on glass can make the glass crack if you push hard. My advice is whay your doing is making the glass running. Basically put your thumbs literally on the glass cut and slight press down and applying pressure slowly and then the cut will crack and then you can simply start make the cut run. As you press down slightly the cut starts to run in front of you and you can follow it around to it meets the start point. You don't have to push hard jist slight push and apply pressure and you will safely keep the cut from breaking. Don't press hard as to much pressure you can break it
After working with glass since 1980 & still in the industry it becomes 2nd nature & this stuff isn't scary at all. Gloves get in the way on small jobs like this- glasses should always be used but.. Just respect the product & never get grumpy with it or you will lose. ....cheers 🍻🍻 oh and never drink & glaze / cut either ha ha
Hi mate, Thank you for great and clear instructions. Can I use this technique for my sliding door glass which complies with Australian Standard AS 1288:2021? Thanks
AS1288 is toughened glass so existing glass can’t be cut . New toughened glass with a hole 👍 if it’s safety laminated glass it can be done by an old skilled glazier but that level of skill nowadays is rare. So just swap out using new glass thanks 👍
@@glassbeveller Haha yes! I bought a circle cutter identical to this for stained glass, and thought ''Now I can get myself some diamonds from a jewellers' shop' {Only joking!} but it's absolutely not like the movies. Curves are really hard, But this is probably one of the hardest cuts to do. {Never done one like this- I'd pay a professional just to save on glass!
Nice. But in the movies the adored bad guys hang upside down on the 44th floor and make one circle cut and then pop it out with a suction cup thingy. As a newly hired apartment manager the owner was showing me how each it is to replace a broken window pane. While doing so he cut himself. For the next 18 months I took out windows with broken glass and carried them to the window glass replacer and then back. I also caused a 4 foot black spark up a wall when I tried to separate two sparking wires with a screwdriver. So I do respect your skills.
OK! Genius!!! :) I have been looking all over TH-cam for this answer! Thank you:) Make a million videos! You did such an excellent job on this one, I can hardly wait to watch the rest of them. I love your accent that you know you don't have;) LOL! BOP
Can you buy the circle contraption or did you make it your self? Would really like to have on! Veey good instructions! Thanks the circle cutter? Or did for sharing!
Atanas Shopski gas oil ? Sewing machine oil is to thick & that is thin oil. I mix a bit of kero with sewing machine oil & put that in the glass cutter or on the wheel. Run the cutter down the glass with NO pressure to make a thin line of lubricant then make the cut though the wet line. 👊🏻👊🏻
Almost ,...use 50 mm between the 2 circular cuts not 25mm & don't push very hard on the glass, push lighter & tap the cut open using a blunt heavy object, like the edge of a tape measure or a ball hammer. but the glass is not as flexible ,so plenty of kero and the first outside cut must be opened from the inside then go outside & open the cut again ... Then proceed. Good luck .
If your putting a hole in already installed glass and its on the sunny side of the building spray the desired cutting area down with your cleaner bottle to equalise the temperature of the glass first and you will have a happy day , one hotter part and it's game over , works a treat cutting flat on the back of a ute tray on a 35° day as well , set your straight edge or circle cutter , spray , wait like a minute or so till the temperature equalises and cut away , if it's your last piece of glass on the truck use the double circle method and the pentagon line approach , it will save a kick in the arse when you go back to the factory to get another piece if your in the trade , works for me and glad to pass tips on to your subs darryn , and nice job mate not a single shell
No this went in the bin. Just done this video for TH-cam & to show the manual way of cutting a circle & for DIY information but yes/ toughen the glass afterwards is always recommended for any DIY..
Also the way your doing is the harder way . You don't have to do an inner circle as your more likely to break it that way and it takes far longer. Just cut little squares in the circle and tap it out and make your way to one edge of the cicle once you get there the whole thing drops out. Can be done in 30 to 60 seconds
That's great. Where can I can get that tool or cutter. I would like to cut the square hole for a small dog to go through the glass door that I currently have now. Is it doable or I have to hire someone to do it? I like to do it myself if possible to save money. Thanks for the video.
straight cutting ? to a rectangle size or a shape or hole ? . old glass is, or can be harder to work with but not unless its like 40 years old or has a colour or pattern through it. clear glass under 40 years old should cut ok. use kero on the glass then cut through the kero.
Hi Darryn, I'm planning on having a go at installing a pet door in a lower piece of glass. Only issue is that it is tinted and I don't know if it's 5mm thick. Is it possible to cut through the tinting and score the glass at the same time and if so, is it even worth it since It's probably laminated and as you say it's meant to be 5mm toughened? I was thinking the tinting may help give the glass a little extra strength?? I guess if I stuff it up I will be calling a glazier(possibly Viridian since I'm in Perth) to fit new 5mm toughened glass anyway. So do you reckon it's worth having a go myself? Cheers. Very informative video by the way!
No, stick on tint needs to be removed first. Use circle cutter to mark out the diameter...5mm bigger than the hole size & cut the tint by hand scalpel then remove tint first , good luck. Pull tint off fast like a bandaid and 90% of the glue comes off with the tint. But Make sure you cut through the tint all around ,
Cheers, thanks Darryn. Would you recommend removing the glass panel to cut the hole or leave the glass in place and attempt the cut. I can remove the flyscreen from the window above to help gain access to both sides at the same time...
+David B you'll break the glass on removal & can be don while in place ... Plenty of kero on the glass around the cut circle . Use small piece of sponge . Large circle first . Open cut both side remember the your chances are good if you get that part over
+darryn malpuss Success! Thank you Darryn, couldn't have done it without your video and advice! Amazing how much effort it took to break the inner circle completely out. Was stressing a crack was going to dart across the pane of glass, but it didn't. Cheers!
+David B great mate 👍👍 in my video you will now notice how hard I actually had to hit the glass inner circle. I need to post something new on glass how to
thanx for sharing, could I do this from only the inside? I have to make a hole for my airco on the attic, and I don't have a tall ladder to reach the window from the outside.
Great Video! You wouldn't happen to know how I could cut a 3 inch hole out of the center of a table top but keep the rest of it intact? I don't wan't to break off the sides like you do in your video. Thanks!
Lucas Edwards if the glass is an outdoor table top it is probably toughened ? Look for tempered stamp in one of the corners. It is better that this be drilled out by your local glazier -AS LESS BREAKAGE RISK. if it has no stamp. (toughened glass can't be cut or drilled) A very skilled glass cutter could do this in 6mm glass or thinner with very little chipping but it is well beyond the DIY . Thanks for watching & feed back 👍
Thanks for the reply.. it is NOT tempered. I know this as I've already cut the hole. After asking I had a friend dropped off a diamond hole saw bit. I put the glass top in a kiddie pool and filled it with some water. At an angle I carefully started the cut and then with gentle but steady pressure I just let the bit do all the work. It took longer than I expected but no cracks! I then gently sanded down the edge with sandpaper. Now to make some sort of insert to help protect the edge. I do appreciate the reply. In my area they wanted almost $200 just to cut the hole with no warranty given if they break it. It seemed worth the risk in my case.
Hi mate, great video. I need to put a dog door in. Never cut glass before but pretty handy in general. In your opinion should i try to do myself to save $150 or just get glazier to do it? I'm guessing pretty good chance of breaking the window given it will be first time cutting glass hey?
Ive been in the glass trade 17 years never has it occurred to me to do the double circle. I do this probably once a month and they always shell. Cant wait to get to work too try this tmoz. 🤯
Great work you did. In my application I need the ring between the two circles. Could you kindly tell me how to save the ring? and can I do the same in thicker glass sheet, say 1/4" to 1/2"?
Hi Darryn. I want to put in a pet door that needs a 267mm circle cut out of a pane that's 550x620 (inside an aluminum frame). It's a fixed bottom window that meets the floor. The house is 30-35 years old. I have called a couple of glaziers and they have told me the glass thickness is only 3.75mm and I need toughened 5mm glass. They say $300+ for the job. What are your thoughts on this? I would love to have the pet door installed there but at this cost I would sooner hack a hole in my security screen and do it there instead. Mate is this worth doing or should I save myself the hassle and just put it on the security screen instead? I would love your feedback. Cheers.
+darryn malpuss cheers mate. Awesome feedback. Perth is on the opposite coastline from me, I'm in Brisbane :-) I'm going to put it in the screen door because it is the cheapest option. Didn't realise there were so many things to consider with a pet door window install but your explanation has made perfect sense of it all. It really does pay to check with the experts.
I have a glass balcony roof, in which I want to make a man hole so I can clean it. I don’t have access to topside of glass, only the bottom. Can I still make a circular hole in it? If not, could a glazier do it?
it can be done but it will break at a later stage. not easy to do ,to hard to achieve for a non glazier. recommend Toughened 5mm glass an swap over the full sheet. laminated glass is very fragile with a hole missing , it is only 2 pieces of 3mm glass. ...
lenny108 your glass door may have safety glass in it so in most cases you can't. But if it's not safety glass then much the same process - just vertical & requires a little more skill as the glass is harder to flex & manipulate where the opening of the cut direction should follow . Break out the glass mess into a vertical box the other side of the door to retain Most of the fragments & waste. 👍🏼
Same process to be used but a bit more kero and more hand pressure required. if the tank is built then manipulating the direction of opening the cut will require more skill. If it's 10 mm glass then a rubber mallet required to open the cut but press the glass then hit as shown.... HitJust behind the open cut to make it go forward 👍
Mike Moynoyxo. , A square requires 4 holes drilled at each crn point with a diameter of 12mm at least. then cut vertical and horizontal to each hole, open cuts both sides. then diagonal cut to form 4 triangles. open both sides again. tap out mess. without a glass saw this is your rough way of doing a power point hole. it will chip a bit. good luck.
Access glass both human and pet should be tempered and is in existing doors. you should have mentioned that as well as you cant do this with existing tempered glass
So you are saying I can't do this on my existing sliding glass door? I thought perhaps it would have some writing in the corner if it was tempered...I was all ready to do this, but now I'm worried.
Sid May yes if the glass is not toughened or laminated. If it’s only 3mm thick then it’s to thin & you need new glass. Just not as flexible so more risk of breakage. Use plenty of lubrication on the cutter
Thank you for this... and help me pray today.. I bought a HUGE glass cabinet to build a paludarium.. 140cmx120cmx50.. And i need to cut a 15cm hole into the side to be able to reach the electronics after it is set up... I might have taken a little to large of a bite to chew because i cant lay it flat to cut a hole into it.. but ok,, it either works or it cracks and the whole thing will have to go to the scrapyard haha..😅🤣 Thank you for this video very clear explenation, ill try and go about it like you showd,, thanks again mate 🙂
Ravana Brahma Rakshas it can be done but the glass isn't as flexible in a frame, only a job for a really good glazier & if the glass is only 3mm thick in an older home ... Don't bother . I would explain but it's beyond DIY 🌹
So, beautiful video---shows me that the movie action of zipping a circle with a cutter and popping it out with a suction cup just may be IMPOSSIBLE, eh?
Toughened glass can’t be cut . New glass required with a hole cut into the panel then toughened & replace the old one New piece must be Toughened, laminated S not a good choice 👍
fridahmuthoni It can be done but way beyond DIY, I have done it & some really good glaziers can’t do it. So they opt for cutting it in 5 or 6mm glass & get it toughened. But the toughened product is stronger & I would recommend anyhow. Lamy used if you needed it done right now & you were way out of the city. Thanks 🇦🇺
kim a lot safer than people think. Glass to me is just like paper, 🙂 splinters in the eyes are the worst. Blink & it scratches your eye ball 😁😁 Glasses required but sometimes we get lazy,
Yes it will !! scribe a circle on first side open the cut from the opposite side , scribe a matching circle on the second side,,,,open from opposite side again,,,, repeat all of the above with a smaller size circle. then do numerous scores opening them from the opposite sides again !!........ use a tapper to break up the centre.......when the plastic interlayer is exposed pour on some methylated spirits to burn out / soften the plastic nibble out to the edge with glass pliers,
I have a cabinet with glass and I'm lazy ASF could I just keep spinning the glass cuter untill it goes through all the way without damaging the rest if the glass if it's horizontal
Anthony Rizzo. not a chance ... but purchase a new toughened piece with a hole in. This is super strong & you wouldn’t break it putting it in. Thanks 🍻
Yeh but I know what I'm doing, once you have worked with glass for nearly 30 years it is like working with a piece of wood to me. Safety glasses are on ,that's the main thing.
looks dangerous to be a glassman. my thoughts are that they cut themselves all the time. and being cut by glass isnt nice, so fine cuts that feel horrible. i rather scratch my self on a rusty nail(im a carpenter)
I am going to try this on a double glazed window. I'm really worried about messing it up. The window is already fitted into the bottom panel of a door. any extra tips?
gamesdisk you need access to both sides of the glass & in a DGU you don't have access. Can't be done. You Need to go to your local glazier , he will get a new DGU made up in toughened glass cut to this size with 2 holes in. also being in a bathroom its probably A safety glass, don't try it. It won't work. 👍
I have attempted many hole cuts and failed before I discovered your video. Great work.
And I see why you need to turn over and 'break the seal' directly after scoring the circle. It stops any cris cross scores following through past the circle score line. Circle cuts are incredibly hard to master and you have made it look so easy.
Thank you.
It was hard to get the camera angle right so it showed a good reflection of the cut opening so people could follow it better 👊🏻 have fun

No problem , happy to share knowledge between glaziers 👍

Nice job.Another method is to cut 2 half moons inside the hole and then open up the criss cross cuts . It fslls out alot easier

They are correct. By law it has to be TGH 5mm as there is no strength in 3 or 4mm glass not toughened,
If your in Perth go to Viridian glass . But $300 isn't bad for a call out and replacement due to skill level involved
+darryn malpuss cheers mate. Awesome feedback. Perth is on the opposite coastline from me, I'm in Brisbane :-) I'm going to put it in the screen door because it is the cheapest option. Didn't realise there were so many things to consider with a pet door window install but your explanation has made perfect sense of it all. It really does pay to check with the experts.
how would you do it if it's a windows with 2 glasses , 1 on each side?
I have a glass balcony roof, in which I want to make a man hole so I can clean it.
I don’t have access to topside of glass, only the bottom.
Can I still make a circular hole in it? If not, could a glazier do it?
Brilliant, thanks
Is it possible, to cut a hole in a already installed double-glass Window? (With 125mm diameter)
it can be done but it will break at a later stage. not easy to do ,to hard to achieve for a non glazier. recommend Toughened 5mm glass an swap over the full sheet. laminated glass is very fragile with a hole missing , it is only 2 pieces of 3mm glass. ...
Dankeschön, dein Video hat mir sehr geholfen 👍🏻
we do this slightly different in the uk ,and i must say i will give this a go and see ! LOOKS A BETTER WAY ...
How did you go. This was the way my English father taught me. He was From Cheltenham ,
nice, but how you do it in glass door, big piece of glass?
lenny108 your glass door may have safety glass in it so in most cases you can't. But if it's not safety glass then much the same process - just vertical & requires a little more skill as the glass is harder to flex & manipulate where the opening of the cut direction should follow .
Break out the glass mess into a vertical box the other side of the door to retain
Most of the fragments & waste. 👍🏼
would this tool work on a fish tank? or would tank glass be too thick?
Same process to be used but a bit more kero and more hand pressure required. if the tank is built then manipulating the direction of opening the cut will require more skill. If it's 10 mm glass then a rubber mallet required to open the cut but press the glass then hit as shown.... HitJust behind the open cut to make it go forward 👍
I've always wondered how this was done. Good vid.
Mike Moynoyxo. , A square requires 4 holes drilled at each crn point with a diameter of 12mm at least. then cut vertical and horizontal to each hole, open cuts both sides. then diagonal cut to form 4 triangles. open both sides again. tap out mess. without a glass saw this is your rough way of doing a power point hole. it will chip a bit. good luck.
Access glass both human and pet should be tempered and is in existing doors. you should have mentioned that as well as you cant do this with existing tempered glass
Andrew Phillips where's the fun in that, can't share all the secrets 😜 I did say it was 5mm glass, this video has helped many
I did also mean to say great work
So you are saying I can't do this on my existing sliding glass door? I thought perhaps it would have some writing in the corner if it was tempered...I was all ready to do this, but now I'm worried.
Anybody willing to try this should be perfectly aware you cant cut toughened glass.
thanks for sharing mate, works even with after a bevy ;)
Best tutorial, thanks a lot!
Can you do this without removing the glass from the frame.
Thanks Sid
Sid May yes if the glass is not toughened or laminated. If it’s only 3mm thick then it’s to thin & you need new glass. Just not as flexible so more risk of breakage. Use plenty of lubrication on the cutter
Thanks, I'm worried about breaking it, the glass is close to 100 years old
Sid May it will be very thin then. If you haven’t done it before then you have very little chance of success
👍
Much easier to do anything with 1/8" glass. The trouble comes with the increase in thickness.
What is the tool called that you used to make the original cuts?
Sorry, forgot to check this for sometime, it's a glass cutter, just use kero to assist
Thank you for this... and help me pray today.. I bought a HUGE glass cabinet to build a paludarium.. 140cmx120cmx50.. And i need to cut a 15cm hole into the side to be able to reach the electronics after it is set up...
I might have taken a little to large of a bite to chew because i cant lay it flat to cut a hole into it.. but ok,, it either works or it cracks and the whole thing will have to go to the scrapyard haha..😅🤣
Thank you for this video very clear explenation, ill try and go about it like you showd,, thanks again mate 🙂
hello. i need to make a whole like that on a glass window which is already in the frame vertically commected t9 the wall. any additinal tips? thanks
Ravana Brahma Rakshas it can be done but the glass isn't as flexible in a frame, only a job for a really good glazier & if the glass is only 3mm thick in an older home ... Don't bother . I would explain but it's beyond DIY 🌹
And the best part is it shreds the fur off the cat every time he uses it......
Superb skills perfectly and pleasingly presented. Peter G Watts
So, beautiful video---shows me that the movie action of zipping a circle with a cutter and popping it out with a suction cup just may be IMPOSSIBLE, eh?
Yep, not possible
Can you do a video on how to cut out a rectangle in the middle?
Really loved your video!!
That was brilliant.... I loved it
Rear sliding glass door are made with tempered glass too tough I do not know if can be done
Toughened glass can’t be cut . New glass required with a hole cut into the panel then toughened & replace the old one
New piece must be Toughened, laminated S not a good choice 👍
So in the movies, where they cut a hole in a glass window in situ.. wouldnt work?
@@johntaylor4726 Hollywood hey.. pffft😂
@@johntaylor4726 I can imagine. I lockpick as a hobby (weird, I know), and always saw that in the movies and wondered. Bit deflated😂
Great! Good technique, i'll make use of it. Thanks
Tq so much sir for the knowledge.
No problem& thank you for the reply 👍
can you use turps or wd40 instead of kerosene?
Alright, now I know that's way beyond my skill level and I can call a pro to do it.
Ben McLeod some so called tradies have a problem & watched this to get a better idea cheers 👍
@@glassbeveller Thanks man, I'm an electrician and was hoping it wouldn't be much harder than making a round hole in a piece of plaster board haha.
Ben McLeod
I thought wiring up colour coded wires would be easy but when smoke appears I was reminded that I’m a glazier. 🤪 ha
@@glassbeveller how about laminated glass
fridahmuthoni
It can be done but way beyond DIY, I have done it & some really good glaziers can’t do it. So they opt for cutting it in 5 or 6mm glass & get it toughened. But the toughened product is stronger & I would recommend anyhow.
Lamy used if you needed it done right now & you were way out of the city.
Thanks 🇦🇺
You can roll the sand paper
Around some wooden dowel
Rod , wet and dry is best
Then would be an issue
Nice Cutting good job
it goes the same technic for a square in the middle of the glass?
Show me how will u make a hole in 12mm thick glass of a big glass sheet
Azmath Ali
nowadays always done on a water jet machine or a CNC machine but very seldom required for a job
A piece of Cake LOL .. good job
Too many adds for a thumbs up.
I can’t turn them off & haven’t approved them either , yes they shit me too. Sorry
I know right but TH-cam added without permission
oil use kerosin ?
Use Kerosene to cut through, or add a bit of kero to thin down the oil.
ok.. thanks for tutorial.. its useful
Nice job mate!!!!!
Bullochman thanks buddy
Great vid! Thanks so much.
there is no way in hell I would be using my fingers to push on glass like that, looks to dangerous for someone who has never done glasscutting before.
kim a lot safer than people think. Glass to me is just like paper, 🙂 splinters in the eyes are the worst. Blink & it scratches your eye ball 😁😁
Glasses required but sometimes we get lazy,
I have a 5 cm diameter hole any way to make the protective circle inside that?
6.38 lam the same process..? knock out one side first..
or cut all circles both sides then tap away.
Great to watch. ( thumb up)
It wont work on 6.38.
Yes it will !! scribe a circle on first side open the cut from the opposite side , scribe a matching circle on the second side,,,,open from opposite side again,,,, repeat all of the above with a smaller size circle. then do numerous scores
opening them from the opposite sides again !!........ use a tapper to break up the centre.......when the plastic interlayer is exposed pour on some methylated spirits to burn out / soften the plastic nibble out to the edge with glass pliers,
What is that tool called
Anthony Rizzo circle cutter available at glass hardware companies & easy to use. This is as easy as it looks if you watch carefully and do as I do 👍👍
I have a cabinet with glass and I'm lazy ASF could I just keep spinning the glass cuter untill it goes through all the way without damaging the rest if the glass if it's horizontal
Anthony Rizzo. not a chance ... but purchase a new toughened piece with a hole in. This is super strong & you wouldn’t break it putting it in.
Thanks 🍻
Yeh but I know what I'm doing, once you have worked with glass for nearly 30 years it is like working with a piece of wood to me. Safety glasses are on ,that's the main thing.
Wow! Thanks for sharing your knowledge. Can you show us this in toughened glass please?
@BirdOfParadise777 thanks very much !
Very impressive. I would have worn work gloves just in case.
fraking spectacular. A+
What’s the name of that cuter plz?
Great video man! thanks!
Slight problem, I need the round bit! I'll figure it out :)
Glass & glazing hardware shop . You won't cut it free hand. Not a chance.
Thank you for sharing!
Ths for sharing. I will try to do same thing. I hope i can success.
looks dangerous to be a glassman. my thoughts are that they cut themselves all the time. and being cut by glass isnt nice, so fine cuts that feel horrible. i rather scratch my self on a rusty nail(im a carpenter)
Genius - many thanks.

Nice job mate ,Cheers
I am going to try this on a double glazed window. I'm really worried about messing it up. The window is already fitted into the bottom panel of a door.
any extra tips?
gamesdisk you need access to both sides of the glass & in a DGU you don't have access. Can't be done. You Need to go to your local glazier , he will get a new DGU made up in toughened glass
cut to this size with 2 holes in. also being in a bathroom its probably A safety glass, don't try it. It won't work. 👍
