Hi Ron, You are so right. Each one of those toolbits has a story behind it. At work we have a giant drawer full of hand ground tools from all the technical folks that have worked in our shop. The shop dates back to the fifties so there is some history in that drawer. Regards, Tom
I am thankful for this video. I'm about to buy a grinder and would have liked a little more about exactly what wheel you were using. Very informative program and the close-ups were great. Actually showing the tool used was perfect and gave all the work to sharpen the bit meaning. PS I bought a lathe today and am about to make chips as soon as we get it from the container into my shop. Keep up the good work! Much appreciated.
I got my lathe moved to my new shop today! It is a Harrison 190 15" long bed, probably from the 1970s and my first lathe ever. It seems to have been used very little and has been stored in a heated ISO container next door to my shop. I'm trying to get a few images together to show from where/to where we moved it. It was a scary experience. I want to thank both you and Keith (Tom too) for all your support leading to me purchasing my first lathe. Grandpa (in the next world) is surely pleased.
Bonjour Laurent, The person you see in the video is really a computer...... You can easily feel the tool pressure go up as you enter the hard material. If you sense the pressure then when one axis loads up you shift to the other and it produces the motion you mention in your note. Thanks for the comment and compliment. Regards, Tom
Hey Tom, I have been watching a lot of videos for probably a couple of years now, after the support and encouragement of my machinist friend that works at Agilent in Santa Rosa. I have joined the countless numbers to have a home shop, and trying my hand at this thing called MACHINING!! A long painful story short, I used to be a Union ironworker, and got hurt and am on permanent disability. At the suggestion from my friend to buy some equipment, I bought my first lathe, after finding out what a lathe was, and have been "making chips" ever since!! It's been a little over three years now in this new world, and I have a whole new appreciation for my perfectionism! That said,I want to thank you for your videos and all your co-horts you've mentioned from time to time. I have learned so much from you all! From Mr. Pete "tubalcain" , Keith Fenner, Basementshop Guy, your buddy Chuck,"outside screwball", And last, but by no means LEAST, is Adam, "Abomb". I APPRECIATE all you guys posting, for if you didn't, I wouldn't have made the progress Iv'e made in such a short time!! Thank You for your dedication to pass along your trade skills as this is a proven method to keep the trades alive and thriving, as you have mentioned several of your mentors that have done for you! Keep it up for all us "NEWB'S!!! Ray!
Another great video Tom! You did a good job demonstrating how to grind that radius tool. Many of the same tricks I use myself, but a lot of my jobs didnt have a specific radius to cut so I would cut I would seemed to fit best. I love hand honing my tools also, do it everyday! You keep knocking out these tool bit videos and I wont have to make any! LOL Hey, we need to find you a good 12" grinder like mine! Those suckers are a beast for grinding tools! Adam
Thanks Tom, The finish on my projects is much better since watching these videos. I didn't realize what a difference a little honing can make. I appreciate your time in showing these videos, Thanks again.
Hi Dan, I'll try to include something in the next toolbit development video. The short story is, Centerline, 1mm, parallel to floor, or 3-5 degrees down on the operator side for large diameter wheels. The reason is to naturally produce the needed clearance under the cutting edge while holding the tool flat on the grinder tool rest. Hope that helps. Thanks for the comment. Regards, Tom
Hi Mark, Yes you can do some things with high speed tools that are very hard or very expensive to do in inserted tooling. After you get practiced up grinding and honing you hardly think about using anything else. Thanks for the comment. Regards, Tom
Hi Vince, I'm sure after I'm gone and watching my estate sale from somewhere above, or below I will get just as excited as the guys making huge scores on my stuff. Having known the feeling you can't help but put yourself back in their shoes. Regards, Tom
Hi Bill, That sounds like a good next toolbit video. I do my internal threading tools a little different than "normal" so it will make a good show. Thanks for the suggestion. Regards, Tom
Yes, I agree with the coments I've read This was a good one. I personally have never seen a high speed tool finished by hand. It never occured to me to do that. Last week I hit a honey hole from someone who passed and it was amazing the amount of tools I was able to aquire. I could have never paid retail for them. Someday someone else will hit the honey hole from my garage. Thanks for your videos Vince
Very great video Tom. At 36:10 the way you manually mill is the way we use it in high speed CNC milling to cut strong or hard material. We call it trocoidal milling that could be very impressive with CNC and also let smooth surface finish. I'm impressed you have that feel(skill) of it when you make such manual milling Like it Tom ;-)
Thank you for your videos. I am taking a precision machining class at a local community college. Your toolbit development videos are excellent demonstrations of what is described in my class. Tremendous benefit from seeing the results of finish honing the cutting edge. Where I come from we would say you walk your talk, by creating the tool and then putting it in the holder and making a cut for all to see the results. Good stuff. Keep it up. I'm hooked.
Hi Adam, Shoot if I get my grandad to buy me a big 12 inch grinder I'll have to sharpen big drill bits like the ones you use. I'll save a couple of toolbits for you to show that smooth southern style of yours. Thanks for the comment. Talk to you soon. Regards, Tom
Hi Shawn, If you are looking down at the part of the tool that is the edge that sees the material first then back rake is when the tip is the highest point. The back rake angle is the angle from the tip back. There are some good diagrams on the web to clarify the terminology. Basically what I'm saying is make it sharper by a few degrees. Hope this helps. Its difficult to put into words. Best, Tom
Not just good for big drill bits, also great for big tool bits! Ive got lots of 3/4-1" hss tool bits in my box I've had to grind. Maybe one day youll find a good used one for sale. I have the 12" Baldor at work, and its great! We didnt have a grinder when I started, so I talked them into getting what I needed. :) I'll have to pull some of those tool bits out one day and do a little grinding on cam.....Southern Style!!
Great work Tom. Here in the UK we use both Kerosene and Paraffin. Paraffin is more refined than Kerosene though both pretty much the same paraffin is more used for lighting and small heaters where as Kerosene is jet fuel and heating oil in rural areas. Keep up the good work. Derek Clydebank Scotland.
Hi Sharg0, Thanks for the comment. I'll have to try that again with your suggestion. I thought it was buildup on the edge but when I ran my finger on it the tool was smooth. I suspect the very light steel wool like was the culprit. It would have worked better also with a heavier cutting lube. Good suggestion. Regards, Tom
Hi Smurf, Thanks for the comment. The book is called "Sink or Swim Metalworking" Its available through Industrial press the guys who publish Machinerys handbook as well as through Amazon. Regards, Tom
Hey Adam, You can do some big boy tools on that big boy grinder of yours. Better charge your camera battery if your grinding on one inch toolbits. Phew, makes me tired just thinking about it. I sharpen my big drills on the belt sander. I like the totally flat wide surface for the big bits. I have a two incher that came with some tooling that has a rotten tip on it that could use a makeover. Talk to you soon. Tom
Hi Inventerius, Yes high speed can be brazed and welded to another piece of steel. High speed is a red hard tool steel. This means it retains its hardness even at red heat. This opens the door for silver brazing and TIG welding. I prefer Silicon Bronze TIG welding myself. Regards, Tom
Hi Jim, Thanks for the nice comment. Glad you found it useful. Support your local Community college machine shops. We need these available for the folks coming up. Machine work and the trades are still excellent career paths. Kind regards, Tom
Hi Shawn, Trepanning bits take a little bit of time to grind. They are relieved in a way that the outer radius does not drag, The internal (smaller) radius needs very little and is dependent on the total height of the tool in relation to the radius. That said start with a flat top tool and add a few degrees of back rake if it chatters. I assume you are using high speed or cobalt tool bits. I would suggest an air blow to clear the chips out of the slot. Let us know how it goes. Regards, Tom
I was not one of your followers that commented on the toolbit videos but I did enjoy them, including this one. I have a drawer full of shop ground toolbits that were purchased at an estate sale. You can't help but think of the person that created them when you use one. Wondering what job he ground the bit for that is something you don't get from an insert:) Thanks for the videos, Rich
Thanks Tom, I will go out and make some various sizes when I get my grinder back. It shorted out but under warranty so they are sending me a new one (dewalt). I'm starting to use more HSS bits. I just got a boring bar set for 1/4" HSS bits and have making some bits for internal threading and notches. Grinding your own bits adds more creativity to the process too. My friend laughed at my HSS bits, thought it was too old school until I gave him a very sharp step corner on the lathe.
Hi Kicker, Industrial Press sells them through their website as well as Amazon. Some Barnes and Noble stores stock them also. Thanks for asking. Best, Tom
Hi irfp, That is interesting. I am familiar with more or less scent being added to cleaning products depending on where in the world they are meant for. It never crossed my mind they would change the formula of my beloved WD-40 for global markets. Thanks for the interesting information. Regards, Tom
Thanks again Tom for teaching me something new, milling a radius into HSS! great stuff A way I've done it in the past is trim a small grinding wheel in a die grinder with a Norbide stick . dress it to size & measure with verniers to the desired diameter then use this as finishing grind after roughly grinding away excess material. it leaves a good finish too, but not like the finish using the mill,but pretty close. Regards - Pedro..
Hi Chris, I'll tell you a little secret. I milled most of the material away for the toolbit in the video. I didn't feel like grinding my brains out for a half hour. Bring on the trolls. I have troll kryptonite in stock at the ready. Regards, Tom
Tom that was really good thanks for posting it. I laughed at your comment everyone is a hero with aluminum! I know using insert tools for cutting threads is the way to go, but if you could show or give your thoughts on grinding a tool for internal thread cutting that would be great.
Large radius on tough material I found faceted approach helpful. Some off the Z and some off the X then the full tool radius. I had less edge build up on the tool. Yours turned out very nice. Nice work.
Very very interesting that has already given me some pointers for other uses for this sort of technique of precision grinding. At some time in the future could you address the issue of how to set up the plate on your grinder e.g. closeness to the face of the spinning wheel, height to axle shaft, angles below the horizontals both side to side and front to back and all related to grinding wheel diameter. (You have probably forgotten all this stuff and do it automatically!!)
I did hone it. I have some round stones and my 1/2" stone fit perfect in the 1/4" radius bit. I frequent the MSC here in San Jose and picked up some hand stones in their excess pile once. Now I put them to good use.
Thanks for posting I have been wondering how to make and use one of these for some time now. Also you talk about welding a blank to something in the beginning of the video. Can I weld HSS steel to something without destroying the hardness? That would be useful to know about.
Tom as always you take the complicated and hair pulling out materiel, and turn it into a stroll down a country lane .hanks so much for all of the technical Data you share with us all. BTW what Book?
hey Tom great video. when making or redressing hand plane irons, I wuld use wet and dry grade pa per rolled over round rod of the correct diameter to help for the rad. plenty of rough to smooth grades in the paper and it's cheep. sometimes you just don't have a stone suitable. thanks for the tips.
Nice video showing a couple techniques to use to form the radius. Mr. Pete (I think it was him) had a video and he used a tapered end mill to build the radius into a thinner piece of stock (like shaper blade) and then hardening it. Finding there are a lot of ways to skin a cat in the machinist world as I watch your videos.
Hi Gopher, Thanks for the comment. You are correct there are many correct ways to do the work as long as you keep you mind open to them. All the best, Tom
nice work! but I am curious. couldn't you get in their with a carbide burr or a finishing endmill? does it always have to be ground from scratch on a grinder? or is that just some code of honor?LOl !
was going to buy some 1/4 carbides for my mini lathe, but i think i'll try making a few cutters first, the lathe needs a tune up, no point wasting my money on the nice tools yet
qwikyking Hi King, You can work for years with a few pieces of high speed steel. Carbide is nice but not necessary for a large portion of typical work. Thanks for the comment. Cheers, Tom
Hi Jack, If it wasn't for dead guys I would have a lot less tools to play with. The same thing is happening with farming. The grandkids don't want to work their rear ends off on a farm when they can sit behind a computer. Sell off the property and collect a pile of cash while they put strip malls in. Damn shame. Best, Tom
It seems a lot of you tube producers will apologize for the length of their videos. I myself have no problems with the length, within reason, and as long as it's necessary for the development of what ever they're to show. I do have a problem when important parts of the process are left out due to time considerations. Good Video. P.S.- I have a world relief map on my wall almost exactly like yours.
Hi Titus, Glad to hear that. Some folks are pretty impatient. That's why they watch videos to speed learn this stuff. Not everybody has thirty years to spare......Thanks for the comment. Cheers, Tom
DirtAddiction Hi Dirt, I'm not familiar with the grades of steel you mention. The tools used in the video are high speed tool steels. They are commercially available as tool blanks. Thanks for the comment. Cheers, Tom
I was looking on amazon for the high speed tool blanks. Those are the three ones that they show. They are all high speed. I was just curious as to what the numbers meant. Thanks for the response.
Hi Tom, great Video! You said you could turn HSS on the lathe with carbide tools. I do a lot of turning of HSS for bullet mold cutters but when i try to use carbide/inserted tools they are toast after just a few minutes. Instead i got some cbn inserts which eat HSS without any problem at all. If you are interested see my video "Bullet mold cutter". kind regards Stephan
Hi Tom, I bet you don't get trolled for suggesting milling HSS, the way I was, still it is a worthwhile technique and quicker than grinding. I have found that plunge cutting in stages is less stressful, but everyone to their own. I must send a link for this video to the troll.
Save the Kryptonite for later as he now denies knowing me, my guess embarrassment has raised its ugly head, ho ho ho he he he! I wonder why so few people have tried milling, but then, if I had to buy carbide end mills at full retail price I might not have dared to try it myself. ATB chris
It's good to know i'm not the only one who cut radius tool bits on the mill.The videos are great. Thanks.
Hi Ron,
You are so right. Each one of those toolbits has a story behind it. At work we have a giant drawer full of hand ground tools from all the technical folks that have worked in our shop. The shop dates back to the fifties so there is some history in that drawer.

Trepanning bits take a little bit of time to grind. They are relieved in a way that the outer radius does not drag, The internal (smaller) radius needs very little and is dependent on the total height of the tool in relation to the radius. That said start with a flat top tool and add a few degrees of back rake if it chatters. I assume you are using high speed or cobalt tool bits. I would suggest an air blow to clear the chips out of the slot. Let us know how it goes.

Maestro oxtoolco lo felicito le e aprendido barias cosas ojala, que nos siga enseñando saludos y que Dios lo bendiga
Amen to that, I have probably a hundred pounds of tool bits, 95% are somebody elses old stuff at least to start with.
Why not turn a piece of the same radius just under-size and wrap some sandpaper around it for honing? Different grits can be used etc.
nice work! but I am curious. couldn't you get in their with a carbide burr or a finishing endmill? does it always have to be ground from scratch on a grinder? or is that just some code of honor?LOl !
I asked this too soon! you just did that in the video!!LOL! my bad!

Its faster and with the burr its really easy to slide over the edge and spoil the tool. Thanks for the comment.
Cheers,
Tom
was going to buy some 1/4 carbides for my mini lathe, but i think i'll try making a few cutters first, the lathe needs a tune up, no point wasting my money on the nice tools yet
qwikyking Hi King,
You can work for years with a few pieces of high speed steel. Carbide is nice but not necessary for a large portion of typical work. Thanks for the comment.
Cheers,
Tom
Hi Jack,
If it wasn't for dead guys I would have a lot less tools to play with. The same thing is happening with farming. The grandkids don't want to work their rear ends off on a farm when they can sit behind a computer. Sell off the property and collect a pile of cash while they put strip malls in. Damn shame.
Best,
Tom
"Everyone's a hero in aluminum" haha so true.
thanks, tom. i was sharping the whole side of my cutting edges, as taking hours to get it to a usable. like your way much better done a few minutes.
You have a book?! need to link that in descriptions in the future..
It seems a lot of you tube producers will apologize for the length of their videos. I myself have no problems with the length, within reason, and as long as it's necessary for the development of what ever they're to show. I do have a problem when important parts of the process are left out due to time considerations. Good Video. P.S.- I have a world relief map on my wall almost exactly like yours.
Hi Titus,
Glad to hear that. Some folks are pretty impatient. That's why they watch videos to speed learn this stuff. Not everybody has thirty years to spare......Thanks for the comment.
Cheers,
Tom
What grade steel do you prefer (707, 727, 851), for making tools with?
DirtAddiction Hi Dirt,
I'm not familiar with the grades of steel you mention. The tools used in the video are high speed tool steels. They are commercially available as tool blanks. Thanks for the comment.
Cheers,
Tom
I was looking on amazon for the high speed tool blanks. Those are the three ones that they show. They are all high speed. I was just curious as to what the numbers meant. Thanks for the response.
Any links to your book or where I could get one?
You need a sky hook for your camera
Interesting chip breaker at 3:40, Ill call it the ramp style.
Would be cool to see some bits ground on surface grinder
Great video, thank you.
Hi Tom, great Video!
You said you could turn HSS on the lathe with carbide tools.
I do a lot of turning of HSS for bullet mold cutters but when i try to use carbide/inserted tools they are toast after just a few minutes.
Instead i got some cbn inserts which eat HSS without any problem at all.
If you are interested see my video "Bullet mold cutter".
kind regards
Stephan
Hi Tom, I bet you don't get trolled for suggesting milling HSS, the way I was, still it is a worthwhile technique and quicker than grinding. I have found that plunge cutting in stages is less stressful, but everyone to their own. I must send a link for this video to the troll.
you also get HSS welding rods but they stupid expensive
Good stuff, thanks
I have CNC milled gear tooth shaper tools like that. grind it close first and it works fine
I think your right.
Lovely
Hi Raul,
Thanks for the comment.

I think we have different definitions of "short video" lol, nonetheless I enjoy the content.
+freelancergin Not so short is what I meant. Thanks for the comment.
Cheers,
Tom
i need to get some HSS blanks
Save the Kryptonite for later as he now denies knowing me, my guess embarrassment has raised its ugly head, ho ho ho he he he! I wonder why so few people have tried milling, but then, if I had to buy carbide end mills at full retail price I might not have dared to try it myself.
