I'm "hardwired" to learn. I have to constantly occupy my mind by working on something, reading, or trying to learn and Mr. Pete's numerous videos are a fantastic way to fill that void. Thank you Mr. Pete.
Thanks
Can we say good buy to reamers?
That's pretty cool that they gave you those cutters, those aren't exactly cheap. Shows that you're still a force on the internets buddy!
👍👍
Dear Lyle, it is so cool to see you so excited about a new tool.......your enthusiasm is contagious...Bravo...PB
I love it!
When I was a kid in the late 70’s (about 19 YO) I worked in an iron shop using a magnetic drill to drill 13/16 holes in the webs of I-beams. Yes, we would pilot the holes with 1/4 inch pilots but that meant that we had to drill every hole twice, and the 13/16 hole took forever. The Milwaukee rep came around one day with his annular magneto drill and the boss let me try it out. I smiled so much the boss bought it right then. It cut through A36 like a hot knife through butter. I love the guy who invented these things!
Amazing
Annular cutters were extremely helpful in the mill. We built and modified much of our machinery so it was often necessary to make large holes in all kinds of odd places.
👍👍
I’d consider these essential tools in an industrial maintenance, fab, machining setting (mine). I’ve used these so many times, they’re totally worth the cost.
Another use I’ve found out of necessity, had a blown tapped hole (with an broken tap) that had to be repaired and used the mag drill and an annular to core out over the center of the hole. Then made a thread repair out of a set screw, Voila!
Excellent idea to get out that hard broken tap
One heck of an idea
Wasn’t a blind hole though was it
I bought the vevor mag drill with 6 annular cutters
Not a bad buy what so ever worth the penny actually making a drill press stand for it so I can get even better use of it
@@jarredsegal6842 no only works with a thru hole
Been using these for over 20 years, a must have cutter for field work.
We used these in the shipyard for drilling the holes to bolt down the engines and reduction gears. The holes were usually good enough that reaming was not required. The holes were measured and fitted bolts were machined and installed in the holes.
👍👍👍
Wow! Those are awesome cutters, Thank you for putting this together.
👍👍
one note, if you do not use coolant, the slug may expand and even with
an ejector rod, will be difficult to remove.....you may have to cool the cutter
down before trying to remove......I made the mistake when I first got my
mag drill of making a pilot hole for the ejector rod......that worked as
well as a screen door in my Submarine......I was on the roof of a commercial
warehouse drilling into the joists through the roof to install HVAC framing.....and
using GatorAde as a coolant.......we live and learn fast sometimes......then my
assistant, a 55 year old guy dropped my brand new $1,000 Mag Drill off the roof......
and complained to the boss that I yelled at him and hurt is feelings......we were lowering with
a rope and pulley and when I put the drill in it's blow mold case over the edge of
the roof, it dropped slightly and he had refused to wear the gloves I provided, so
when it started it's 30 foot trip down, the rope slid through his palms and burned his
delicate hands.......oh the horror of being a sub contractor who has assistants provided for them.....
need less to say, the case was destroyed, but the drill survived.......
Sounds like you were working with Bubba
Great video, thank you. Those cutters were developed for use in structural iron, to make holes fast n clean with the mag drill. They are a huge addition to the machine shop. They also work well when making holes in light gauge tubing.
👍👍
Thank You Lyle Peterson... Another AWSOME show. If I do purchase this set I will probably use about 20 or 30 times on future products before I kick the bucket. Than they will be found in an estate sale by some unknown fellow or lady to give to her husband, HA, (lucky fellow). Life is soooo much fun making projects with new tools... 🤩... Lyle I watch constantly but comment rarely, LOVE ALL YOU DO... TM
Thanks
Thank you Mr Pete. Looks like a very handy set of cutters. I have seen a tool holding ER collet that has pin that closes down on the flat spot when you tighten it up.
Thank you, I have never heard of such a thing
I was looking at those recently. From what you showed, the look worth the price. I will have to pick me up a set now. Looks like an arbor for these cutters will be a future project for a lot of us.
Yes
I am only commenting because we share the same initials and surname, although differently spelt.
I use these cutters and made a 20mm holder to fit an R8 collet in the mill and another 16mm one to fit a drill chuck on the lathe, both with two grub screws for drive.
Great video Mr Pete. Thanks for posting. I have used them in the past with a mag drill, but never thought about using them with the lathe or mill.
Thanks for showing an additional application. 👍 Dan
👍👍
Awesome! you are amazing! Your passion for metal work shines through!!
Wow, thank you!
I use them all the time mr. Pete Thank you for sharing keep it up
Dear Lyle.....My Jancy Slugger, now owned by Fein, will drill at 440 rpm, and drill a 1 inch hole in 1 inch plate is less than 60 seconds..
....the through feed coolant allows cool cutting at the fast rate of 440 rpm.....
.it is one really amazing tool, I have a video of it cutting aluminum on my channel......
and I am finding all sorts of ways to use the magnetic drill for small parts and tall parts...
I keep a 3/8 x 6 x 18 inch plate that I can clamp the small part to and the magnet holds
the drill to the plate, and you do not have to have a hole in the plate for the cutter to pass
through, as the slug stops the cutter from cutting when it breaks through and does not
cut into the plate....Awesome Tool........
Thank you, Paul. I was afraid to use power feed on the Bridgeport. It was my first time using these cutters, and I was unsure of the required feed rate. Plus, I did not have forced coolant.
I was using a Ø20mm one earlier today. I use them with my mill in an ER32 collet, they are a bit tight in a Ø19mm collet as 3/4" is 19.05mm. I was cutting 3mm thick stainless equal angle section. I also use them in the lathe tailstock using ER collets where cutting a large diameter hole can save a lot of time over drilling and boring. The plug out of the centre is also useful as raw material for some small items when needed.
👍👍
Wow, those are impressive! I'd like to get a set one day. Thanks for sharing Mr. Pete!
I purchased a Jancy Slugger magnet dill and cutters in the 90s and they have been very helpful. I used it a lot to drill holes to mount things on truck frames. I have cutters from 1/2 inch to 2-3/8. One great feature I found is if there is a hole that is not quite where it is needed, the annular cutter can be used to cut a hole with another hole on the edge of the new hole. If you would dull one, Fastenal can sharpen them through their tool and cutter grinding services.
Thank you, I like the idea that you can move the hole. Totally unlike a twist drill.
great show ! just what I'v been needing
👍
Thank you! never seen these used before.
I have been using the Hougan brand hmd-904 swivel base mag drill with their brand of high speed steel annular cutter since 2011 drilling holes in semi truck frames for mounting pto accessories such as pumps or blowers or compressors and axle assemblies. Recently I was having issues drilling in a particular brand of heat treated frame rail, so I ordered the Hougang Copperhead carbide tipped annular cutter. The 5/8 cutter drilled over 200 holes and it still cuts like new. Annular cutters are the way to go. By the way , the Hougang mag drill weighs about 1/3 of what my old Black and Decker mag drill was.
👍👍👍
Amazing cutters mrpete.Thank you.
👍
These and a mag-drill are two of my best friends at work. I'm a structural steel fitter/welder that often has call to move holes to where they should be, or make 'em where they aren't on a structure member.
We use cutting fluid in place of oil. Oil being a big time fire hazard in a shop full of plasma cutters, torches and MIG welders.
👍👍👍
For a Slugger or knock off magnetic base drills! Those cutters are fantastic.
I called the one at work Mr Sluggo.
Never, ever thought of of home-shop uses! Very neat and thank you!
Ideas for the brain.
👍👍
I'm looking at buying some! Thanks for the info and demo!
Those are real time savers. Great for what you demonstrated and of course a must have with a mag drill for fab work.
👍👍👍
Link at bottom to the original history.
Mr Pete, I started using these cutters in the USAF Machine Shops from the original manufacturer Hougen Manufacturing. Back when they were known as "Sluggers". Dr. E. Douglas Hougen was the inventor of these annular cutters and they saved a lot of time when cutting large holes, especially in think metals. They took a lot less time to punch a big hole in stock then step drilling. I used them to punch out a rough hole on lathes and mills to get as much material out before boring, drilling and reaming to final size. I made adapters to hold hold these sluggers, then drilled and tapped two holes for set screw at 90° to lock them in. They can be used in a non Weldon collet but they will slip without that positive lock. I would also drill a hole through the shank big enough for the head of the ejector rod. Then tap it for a set screw. I would machine a small part that would slide freely in the hole with a step that would fit inside a spring like a short guide spud. Then slid that in the shank and cap it off with the set screw so that it pus just a little pressure in the spring. Those adapters worked great.
But one thing you need to do id use a lot of cutting oil or fluid and back them out to clear the chips if punching out deep holes. These things can get hot, expand and will lock up and brake if you aren't careful, especially in thick aluminum. Unfortunately I had some young guys in the shop that always wanted to run these Sluggers faster then they are should be and I've seen my share of shattered cutters and ruined parts.
I've also used them to enlarge a hole by making a guide for the cutter, something similar to the guide on a counter bore or spot facer. Sometime we had to think outside of the box, with common sense and caution to use what we had on hand to get things done. We didn't always have the budget to buy a one off tool that might be used once or a few times. I also used the center slug or donut hole out of the cutter for other parts to be made out of. Sometimes it was quicker to cut a slug out of a metal plate to machine a small part then wait for the round stock to come in. That is if I had the right metal plate or other stock on hand and a slugger cutter that would give me a round slug big enough to use. Like I said, sometimes you just have to think outside of the box to get the job done.
But here is the original history of these annular cutters by Dr. E. Douglas Hougen. Hope you enjoy the history.

Thank you for an extremely interesting comment. You gave me lots of advice and good ideas. These cutters are new to me and I have much to learn. I am eager to read the history of these cutting tools. Thank you very much
@@mrpete222 Sorry about some of the misspelled words, I'm not much of a typist and I should have gone back and check. I have big fingers and I'm always fat thumbing these keys.
BTW, you might be surprised at how we came up with ways to make or fix parts with what we had on hand. When you have a Colonel breathing down your neck that wants something fix in a hurry and you know safety must be adhered to, people can come up with ways to accomplish the mission that holds to Tech Data and safety standards when pushed. Remember the old saying "Necessity is the Mother of Invention". I was proud to serve with the most talented people on the planet.
Did you ever get a chance to make those Mill Parallels I sent you some pictures and plans to make them?
I used a magnetic drill with annular cutters many times in a structural steel fabrication shop job. They work great.
Thank you, I will have one of those drills pretty soon
Those pointed pilots also serve to locate the Mag drill into a centre punch layout mark.
Looks like a fine piece of equipment
Nice review, Annular cutters are great to have in the shop.
👍
Very nice review of the Vevor annular cutter.
I can see already would be a very useful tool to have.
Thank you for sharing.
Thank you to Vevor also.
Take care, Ed.
👍👍
Great video I use them often for bigger wholes and for milling plastic flats like an end mill
👍
We used to use these in a Bucks Drill for drilling clearance holes for bolts in structural steel. We eventually switched to an hydraulically powered punch. The holes we made were seldom bigger than 1-1/32” so the punch worked well. For holes bigger than that it was the annular cutter.
👍👍
Pretty cutters, thanks for sharing sir
Nice job Mr Pete. I had no idea those thing cut to such close tolerance
Thank you!🙂
👍
Bloody good job, sir.
These cutters are great , I used one to drill 5/8 holes , many , with mag drill to make welding table top !!👍👍😎
I watched James Kilroy’s video on annular cutters several years ago and have been using them ever since.
Thanks for sharing 👍 I'll have to rethink using them.
I use these on a bridgeport as well, in a collet. I always use the center pin, even if it can't eject the slug, it allows easy line up with a punchmark
👍👍
Wow ! What a great way to drill larger holes.
Nice tools, wish I had something to run them in.
Great video
Have a great day
Great Video, Thanks. Just a couple of things to add. I cut a lot of holes with the mill using a Hougen R8 arbor (PN #49849). It goes into the spindle and the grips the Weldon shank of the cutter. It also has a port that can be attached to a coolant line! It floods the cutter from the inside out with lots of coolant. To peck or not to is the machinist choice. If the RPM"s drop, then there's probably a build of chips between the flutes. That needs to be addressed quickly before the cutter shatters. BTW Hougen offers a stacked plate cutter grind. The cutter will go through each layer of material without the flange on the slug and then start cutting on the next layer. Have fun cutting holes!
Thank you for that information. An anonymous donor sent me an R8 adapter just as you described. It will be in future videos.
Excellent video on some great tools. Thanks for sharing.
👍👍
That's impressive
Ty Mr. Pete
😄
There are annular cutter holders with a spring setup for the alignment pin.
I use mine in a drill press to cut aluminum.
I also have a set that goes up to 3/4". They are so much better than twist drills for making holes in thin metal.
Best tool ever for drilling truck frames.
👍
I love my annular cutters, do not know how I got along with out them all these years.......cheers Lyle....Paul
I am now of the same opinion
They work great. Good job 👍. 😊thank you.
You're welcome 😊
Nice set Lyle.
I used to use those almost every day when I worked as a fabricator building gravel conveyors. If you find the right chuck for it, it should have a spring-loaded center pin that ejects the plug all by itself. They really are great little tools. I'm glad you found a use for them in your shop. 👍
Cool, thanks
Mr Pete have been using these on the mill and the lathe, made myself an adapter, Have had many items from Vevor and not had a bad one yet
👍👍
annular cutters are the best thing since sliced bread, particularly when you get an adaptor for your normal drill press instead of having to use a mag drill to drive them. I have not used a drill bit over 13mm for years.
I think I am converted, just like you are
Thanks for the video! I've got a set of no name I picked up at the flea market and love them. Works in ER 30 collets also.
👍👍
I have 2 but intend on getting a set and I love them . Handy as a shirt pocket they are!
👍👍
the manufacturers say once you start drilling,
do not peck drill for risk of getting chips under the cutting lips...
and if you are cutting/drilling tubing, or multi layers, you need to make sure to
remove the slug before continuing to the second layer.....and if that slug
is still hanging around in the tube, it will be grabbed by the cutter
and raise Cain and throw your part or drill askew no matter how
secure it is, or break the cutter......I had a cutter grab while horizontal drilling on an
I-beam and the area of contact for the mag base was not optimal, that bit grabbed
and knocked the drill off the column and snapped the bit right 'Pronto"......I was on a ladder
at the time and it got my attention real fast, I decided to get the 'Smoke Axe, also know as a
Blue Tip Wrench' and use it.....that was a little safer...
Wow, that sounds scary
Those seem to work very well. I bet they would work good for making brass bushings.
Yes, I will show that in a follow up video, thank you
My mag drill has an oil reservoir and the center pin not only allows you center the cutter over a center mark but when you start drilling the flat on the side of the center pin allows the cutting fluid to flow into the center of the cutter which automatically liubricates the cutter while it runs. Great tools.
👍👍
I used them for drilling holes in truck frames and building crusher plants. You can special order cutters for different jobs. We needed one to go through 5 inches thick steel on a jaw crusher frame. A one inch hole took about an hour to go through 5 inches.
Wow, 5 inches deep
In the mill, I have used them as a you would an End Mill. Both direct skimming/cutting on a horizontal plane, and also used the side, cutting in a vertical. Steady as she goes.
I need to try that now......totally makes sense
I hope you do a video on the adaptor you're going to make, that way we at home can make one too if we'd like. 👌
What I like about annular cutters is like you said it doesn't reduce everything to chips, so if you're like me you can save the plugs and all off cuts for future projects, as materials are not cheap. 👍👍
👍👍👍
Thank you good content.
You can definitely use these in drill presses, but the mag drill has a spring up inside the arbor, so when you use it with the ejection/center pin, it will aid in ejecting the plug from the annular cutter
Thank you, and I will soon have one of those mag drills. And demonstrate exactly what you are talking about.
Pete, angular cutters are the best for concentric large holes drilled manually. I used them on structural steel fabrication and they make Lots of shavings! We would use a scoop shovel to clean them up. The slugs were a trip hazard though. We used sizes from 5/6"to 1 1/8".the corners on the flutes get rounded off making the cutter dull. I think we sent them to a sharpening service. Use lots of oil as it helps dissipate heat. I have a set of hole cutters for sheetmetal from Cornwell tool. Step drills and my Cornwell set are the bomb for concentric holes in sheetmetal. AL B.
Thanks
This is a wonderful tool. You can put a relatively large size hole in no time without pilot hole. It is worth having it. With the help of an adapter it can be used on a drill press, lathe, mill press, not just mag-drill (of course not hand held tools).You can order any size you want, like for tapping threads.
I HOPE THEY SEND YOU A 100 THINGS TO TEST AND 100 FAT CHECKS. you deserve it. I will be watching. Here that Vevor??? Send this man money. I believe every word this man says.
Thank you very much, I hope that Iris at vevor, reads this comment. Lol.
good review, I'll check them out.
My son used to work for Hougen here in Michigan. Hougen is famous for their annular cutters and their magdrills
MJ
👍👍👍
Thank you!
Where I used to workwe used those cutters in a magnetic base drill to drill holes I'm the tempered steel of truck chassis rails. The power of those magnets has to felt to be believed and the ease with which the cutters bore through hard steel is very impressive!
Thanks, Mr Pete! I'd noticed annular cutters in some other vids, (This Old Tony? OX tools?, Joe Pie? etc. dunno) but can't recall seeing them cut.
When I have jobs like these I pull out an old hole saw, sharpen it, grit my teeth, and get prepared for excitement. How much nicer to pop one of these into the old Bridgeport.
Nice of Vevor to give you a set, and I notice the drills are affordable, $200 to $370. Not sure if that gives me confidence. A quick check for prices of Milwaukee mag drills show them to be from $1000 to $1,700 for corded, and, gulp, $2700+ for a battery version. Don't think I'll ever need one, whew.
If you could stand the swarf and drill in one pass I bet the OD wall would be prettier. But, no, neither could I. Would be a nice afternoon project to build a holder.
they cut a clean hole. nice.
I prefer to use water soluble oil when using annular cutters. I think the water vaporizing carries away more heat, and the residual oil is a fair lubricant. I have also used cutting oil, which works almost as well.
Thank you for producing this video!
If you have ever heard of Project Farm, he did a review of annular cutters.
here is the link to that video.
th-cam.com/video/OZX-51QDGZI/w-d-xo.html
I have heard of him. But I have not seen that video, thanks I will watch it.
I saw that. The ones w/carbide teeth were really good.
Great video !!! I have to get a set of these.
You should!
I have used these for years. they run in size from 7/16 up to 2 1/2 by the 1/16.You can use these in a drill press but you need at least 3/4 H.P .I use them in my Wells Index 747 mill and they are great as well as my south bend 13.They will save you so much time it is un real...
👍👍
I love these. I have never seen them before but it makes me believe they could replace many of my larger twist drill bits. I reckon a slow steady feed would produce a better finished hole and the slugs can be used too. Thanks for the video.
i have used them for some years now, once you use them you will never go back to twist drills of the larger size. I have a mag drill and an adaptor for using them on my drill press.
@@bruced1429 Cool. Can they be resharpened?
@@lagunafishing yes ,I send mine to my supplier for resharpening, which is not very often, they stay quite sharp if not abused.
@@bruced1429 Okay thanks, that's reassuring.
I bid on some of those at an auction but the price went out of reason very quickly. Nice review. Thanks for the video keep on keeping on.
👍👍👍
I’m building a gantry with about a hundred holes so I can dismantle it later. Drilling holes was not going well, and I can’t afford a Mag Drill. I used carbide insert on my drill press, that was a waste of money. I rigged a couple of annular cutters to fit the chuck, and it was a dream come true. ❤
👍👍
Interesting, never seen one used before.
Good info. Ta.
I ordered my set just now. Mr. Pete, go ahead and build a chuck adaptor for those, that would be interesting. Thanks
👍👍👍
Wow those things make some serious chips!
I think the imperfections are the result of backing the drill out for oiling and chip removal. Had you been using a drill oiled from the top and not cleared the chips out the hole would have been cleaner I think. Also, there are carbide tipped versions of annular cutters which last longer.
I was just thinking this.
Thank you for the tips. I will be doing much experimentation.
I gotta get me a set! I figured being 'annular' i could only use them once a year! lol
lol
thanks for sharing
Could use them for O-ring grooves.
A long time ago I stumbled upon the annular cutters. We had thousands of holes to drill into steel; went through hundreds of different drill bits. Went over to a tool supplier who turned me on to a mag drill with annular cutters. Took only three days to finish the whole operation; we spent the same amount of time and a whole lot of money in drill bits getting nowhere !
👍👍👍
NICE SHIRT!
Thanks!
I have an R8 to Weldon adaptor for my Bridgeport it has a spring in it for the ejector pin I have a reoccurring job that i have to cut 1/2" slots in 3/8? stock I drill out each end with an annular cutter and mill out in between they work great for this
👍👍
At the cost of Brass these days, that saved core is worth a bit. Would be useful to cut some stock for turning if you run out of short brass rod.
Great point!
They have mt2 and other styles to weldon adapters. Some come with coolant ports
Thanks
I can see Bubba ramming it through in thirty seconds without safety glasses and sparks and blue chips flying all over the shop.
lol
Those are great . I own a few of them and my advice to anyone who wants to get them is to buy an adapter for them be it R8 or morse taper . They will save your tools and make them easier to use and center on the work because of the centering pin .Don't forget slow and well lubricated.
👍👍
Those center pins work as a ejector, but their main purpose is so you can line the cutter up with your center punch mark. If you make a holder, you need to make it hollow for the center pin, otherwise you'll have no way to line the cutter up with your mark.
i have used them on my drill press as well has my mag drill. they work fine on a drill, press with an adaptor for them. they are quite okay up to 3/4 in diameter drilling only up to 3/8 material on the slowest speed. use a cheese stick lub for Hougen corp and you are all set.
👍
