How To Grind a Chip Breaker Tool Bit

[@sethbracken]

Pretty cool that your dad’s little trick is now available for generations to come.

[@yawpaw9796]

Great comment! After all, ideas endure at the bottom of the cookiejar.

[@robinmorritt7493]

For us man cave dwellers who don't do a lot of turning, and maybe mostly use inserts, this information is the difference between thinking something and knowing it. It's a great help. Thanks, Adam.

[@doloresnutland8893]

Great fan here in France of all your excellent videos. 71 years old and never had the courage to grind a tool. Followed your instructions. Made a tool. Worked like a dream on aluminium. Even the chip breaker worked!. Brilliant.

[@tmenzella]

I love the way you talk about all the tips and trade secrets your dad (and grandad) passed on for you to become the top machine man you are. Great video again thank you Adam.

[@brianhind6149]

Thank you for the elucidation. I am NOT a machinist, & if I need machine work done I take the job to a machinist. Your video & explanations answered all the questions I had about tool bits. Thank You !

[@dalejones4186]

Hi. This is exactly what I needed. I’m new to metal working and this explains very well how to make your own cutters. Thanks Adam.

[@emaronson]

I am an 82 year old man living all my life in Houston, Texas. For a time I owned part of a company that financed machine shops. At that time there were more than 1000 machine shops in the Houston area. I really enjoyed visiting prospects and customers and getting a VIP tour of their shops. Looking at the machines and watching the machinists at work, seeing the raw materials and finished products was fascinating. But I didn't have the slighted idea of how to machine anything. Now after watching at least 200 of your videos I'm much better informed. You are definitely a master machinist. However my interest is in you the person. You are an extremely hard working, very ethical and generous man. I admire you more for that than your machining skills and knowledge. Also I have a son named Adam and he shares your fine qualities.

[@Abom79]

Thank you! Very humbled by your comment!

[@MrRvandeW]

i claimed the lathe at my work last week as it was just collecting dust and been messing around with it aswell as trying to grind different high speed toolbits, this is showing up just at the right time. thanks Adam

[@FireballTool]

Great tips Adam. I look forward to the next tip video.

[@had2galsinthebooth]

Maybe I'm just easily entertained but that was pretty cool. Especially the view of the steel rolling through the groove at the end. TY.

[@garywills5682]

Much less pressure on mchine , tool n part. Work equally as well on shapers n planers. I ground bits for our shop in the 70s seemed to be a steady part of my job. Even after making forman , boss said hey Gary got a special bit i need. My fingers got to be burn proof after awhile. Good job on the bits Adam nice video.

[@skuzlebut82]

I used to make carbide chip breakers at a tiny little machine shop called Madill Carbide. Only 7 employees and we made carbide inserts by the thousands for the local aerospace industry here in Wichita, Kansas.

[@xenonram]

I'll bet that's not around anymore. Shame.

[@skuzlebut82]

@@xenonram It absolutely is. They're still going strong. I don't work there now but I stay in touch with them.

[@toolbox-gua]

I don’t miss any of your videos, to learn and relax.

[@howardtoob]

The amount of knowledge that you have is incredible. Your generosity in sharing it is even more do. Thanks!

[@workwillfreeyou]

Thank you. Believe or not some small shops have a hard time buying commercial carbide for every job.

[@ericnolan6877]

Even went old school with the lantern holder. Nice touch..

[@joeszabo4237]

Good video Adam as always. I've been in the trade for about 40 years and saw you just posted a new video. Even though I know how to grind my own tools, I figured lets see what Adam is up to with this. My point is that we are never too old to learn something new. Great information for the folks starting out. Thanks, as always I enjoyed watching.

[@prodoverjeff2876]

Joe, I have the same time in maching as you and still spend time on weekends watching Adam's videos. Nice to sit back and watch somebody else do the work.

[@yawpaw9796]

People who starts off a comment nummerin years of trade are goofs .-AvE

[@edwardkawecki8101]

Starting out first year machine shop taking the time learning to get my cutting tool or drill grind just right and then showing ol Mr Calvin our great shop teacher my proud job he would take a good look at it and say not bad Ed. Then take it and jam it in the wheel and mess up the whole grind and say here now do it again! Yep got pretty good at sharpening bits and tools LOL

[@ellieprice3396]

Adam, thanks for demonstrating a trick I've been using for years. If chips refuse to break try grinding the cutting edge slightly below the chip breaker groove. For best results the chip needs to forcibly contact the rear edge of the groove instead of sliding over it.

[@jeffryblackmon4846]

Thank you, Adam! The difference in finish was huge.

[@Rprecision]

Great tip! I'm a home guy and need HSS to get through some projects. Now, I need a good pedestal grinder like that!

[@bcbloc02]

HSS has saved the day for me many times! Being able to grind it properly is a valuable skill. Good tip! :-)

[@Abom79]

I still use it all the time Brian 👍🏻

[@G-Man-kc2nm]

I have always been interested in machining. I often thought about buying a lathe. You make it look so easy because of your knowledge and experience. Thanks for sharing a great trade.

[@rogerscottcathey]

This #tipblitz is cool. Kind of like in the old days home shop and project magazines had short-cut tip issues.

[@weshowe51]

Definitely a good tip, Adam. Well worth watching this... short, sweet and information packed.

[@SteveSummers]

Very handy grind. Thanks for sharing Adam

[@adamross1482]

Hey Adam, Could you do a video on feeds and speeds would be really helpful. Cheers

[@fiorevitola880]

Adam; thanks for showing this again, it's going to help me tune up my cutters.

[@molaisonmaker6896]

Thanks for sharing some of your tips and tricks for grinding. I really like the idea of this tipz blitz series.

[@alexbarnett8541]

I'm definitely going to try this grinding technique. Always like seeing different ways of doing things.

[@pcmasterwraith7676]

i was a terrible anything metal guy but if i had had someone like you teaching me i probably would have prevailed

[@codyramos3200]

it takes time to learn .. i started with a 4 1/2'' grinder an drill for knife making an kept buying tools continued to learn metal working . im no pro but ive come a long way

[@SnodProdMusic]

So helpful 😁! I love learning these little things that make such a difference in machining!

[@stephenwright7065]

Very cool! Thanks for sharing. I could definitely tell the difference in the finish

[@andyZ3500s]

Some great advice Adam. When I first started machining in the home shop the biggest mistake I made was not learning to grind HHS properly.

[@andyZ3500s]

I can't even write HSS correctly. Seems That I'm still not that smart!!!!

[@bsideadventures2180]

Love this content. Can't wait till you do another tool resto.

[@douglasblacke9360]

Hi Adam, I recently "discovered" your channel and I've enjoyed watching it immensely. I appreciate your dedication to your craft and your approach to problem solving as well. You are a licky fellow to have followed in the path of both your father and grandfather, and I'm certain they're very proud. I have two suggestions that you might find interesting: 1) In my woodworking hobby I've found it interesting to use a magnifying camera from time to time. The one I use (purchased on Amaxon) goes from 10x to 200x and was not expensive ($50 as I recall). It connects to a a computer via USB cable or to a TV/monitor with a RCA jack. 2) I've noticed one of the most common things you do is "touch off" - make contact to determine when a cutter meets a surface. It would be quite easy to arrange a 5v electrical circuit that would illuminate an LED upon contact since all the hardware you use is conductive. Don't know if that would be useful, but it came to mind. Thanks for reading this far. I look forward to learning more about machining! PS - Your buddy the welder is quite good! - I've done a little TIG welding and he makes it look pretty easy!

[@Just1GuyMetalworks]

Cool😎. I've had tonnes of bird nest issues with 1018, definitely gonna give that a shot, thanks.

[@dcw56]

Sure beats heck out of those huge birds nests I've seen on some 6061 turning! Nice instructional vid for the guys, Adam.

[@imagineaworld]

Thanks for uploading Mr. Abom!!

[@rodneywroten2994]

Thanks Adam

[@arockpcb1347]

Very nice. Hadn’t see that trick before. Thanks Adam

[@tinkermouse-scottrussell3738]

Great tip Adam thanks for taking the time to share it with us. Play Safe From Elliot Lake Ontario Canada.

[@griplove]

Great tip, trying to teach myself how to grind HSS tools and it’s often difficult to determine what I’m doing wrong with out someone yelling over my shoulder. This should help greatly thanks for sharing!

[@AllThingsMech]

Been looking forward to this one ever since I saw your post on IG about chipbreaker tools a couple months back. This is really cool, thanks for sharing Adam. Going to try my hand at this once I get my new shop set up and get the lathe wired back in.

[@CraigsWorkshop]

That's a great method Adam. I've never tried this, but I definitely will be. I quite like using HSS.

[@torniaccio]

Nice tip Adam! I would like to add mine: with this kind of tools it's important to use coolant, high temperature can cause the sharp edge to become dull too quickly.

[@walterkucharski4790]

Thanks it takes me back to tech college 50 years ago!

[@JAMESWUERTELE]

Wait a minute?! You and Tony making the same (sameish) tool? Blows my mind!

[@andrewyork3869]

Abombs chip breaker works much better

[@vizionthing]

its a form of quantum entanglement

[@codyramos3200]

thats some old school machinist ingenuity . i work with a older dood about 60years old that builds harleys he learned a lot from his father, has vintage - antique tooling he got from his dad when he passed im always impressed when i go into his personal work shop. old tricks of the trade.

[@AntonioClaudioMichael]

Great video abom79

[@EverettsWorkshop]

That's a cool idea, thanks for sharing that. I'll definitely be making a couple of those up!

[@pgs8597]

Thanks for sharing, good tip. Cheers Peter

[@girliedog]

Excellent tutorial clear and concise, just the way I like it.

[@mrscrapper3331]

Wow! Never even heard of this! I’m running out to the shop and try it right now!

[@whitehoose]

Hi Bom. Something I always see and have never understood - I was always taught to use a whet, oil or mudstone with as much "whet" (oil or water) as possible , the only exception being a slip stone where you make your slip mud and then do your best to keep it going and to use it as your abrasive. The others you use the surface of the stone - so the aim is to keep the surface clean and well lubed to get the best contact to wear down the edge. What am I missing - it seems to be the same aim but I always got my knuckles rapped if I dared let the stone get dry.

[@kevinzucco8358]

Thanks for the great tip on how to grind in a chip breaker.

Seen all your videos now. NEED MORE ABOM!!

[@stevenking6400]

Love to see this content for shaper tools

[@notsofresh8563]

Hey adam, this is a great video and i would like to see a series of short tip videos like this regularly from you. The name for the tips videos should be "Chip Control"... i know it was the video series about tool bits you did years ago but it is also a great name for general tips videos. This video made me think of that as a name.

[@debbiebissel50]

Nice video Sir! Man between that grinder and the carbide grinder I had seen you use in an earlier video it looks like my old shop, I may have unmentioned earlier that we didn't get insert tooling till I worked in the machine shop for 25 years so I've heated up some fingertips and wish I could still do it.Thank you JAKE.

[@Abom79]

Great way to learn! Grind some tool bits before you get the easy to use carbide inserts. 😎

[@chrismate2805]

Hi Adam, can you discuss parting tool types, the different tip holder shapes, some looks very different than others and the with of cutting tip for which application.

[@jessshane1339]

Will you please do a video in the process of repairing the bearing housing on an endbell?

[@harshreality3291]

Im amazed how fast a grinding wheel cuts through something that rips chucks off a slab of metal

[@alexvonbosse5090]

Excellent video w/explanation! Thanks for sharing!

[@63256325N]

Thanks for the video.

[@AntonioClaudioMichael]

With the chip breaker bit its smoother the chips are nicer as well as the finish is a lot nicer

[@CursedLemon]

I've been waiting for a video on this subject from you! Great skill to have.

[@ernerstowerdum3942]

Simply excelent video, very beste tecniques for sharpening hss tool bits..could you make some other videos of sharpening for other materials or sharpening carbide tippes tools?, thank you very much for share your knowledge

[@shawnmrfixitlee6478]

AWESOME , really great tips Adam .. ENJOYED

[@prodoverjeff2876]

Modern inserts use chip breaker designs that have become almost proprietary designs of the tool manufactures. That is why two similar inserts from two different manufacturers will provide different results in surface finish, tool life and chip breaking. When I was learning how to sharpen turning tools, I often saw the difference when I reground a tool originally sharpened by old timers.

[@franciscogonzalez7402]

[@rickbrandt9559]

Finally a real ABOM video.

[@DavoShed]

I think to many new home machinist rely on insert tools exclusively. Great to see you doing a HSS grind instructional. Still looks like your cutting butter on your machines :)

[@EdMeyer22]

Those chips are so satisfying

[@yhnbgt365]

60 years ago I remember watching my father turning extruded aluminum tubing to make telescope parts. Sometimes the chip would stay together and form a long spring-like chip that was several feet long. We used them for Christmas tree decorations. Just the opposit of what a chip breaker tool does.

[@elsdp-4560]

THANK YOU...for sharing. Enjoyed.

[@WreckDiver99]

Adam, I think this would have been a GREAT videos...but I was pretty much lost from the get-go because I did not understand the tool geometry at all. Cutting edge, relief, etc. Yes, I know very well I can find books on this, but I kind of thought that's what these videos were for (to help us understand some of these things). Even after you showed the two being used on the lathe, it was difficult for me to understand the basics of these two different tools. On another note, I'm kicking myself to NO BLOODY END...about 15 years ago my grandfather passed away. I didn't understand that he was a "tool maker" back when he worked in Automotive. We really never talked about it...anyway, when my grandmother passed away many years after him we had to clean out the house. I found all kinds of bars of steel, etc. I had no use for them, and we took them to the recycle yard (we're talking over 4 TONS of steel...various bits/pieces, cut-offs...most way too small to do anything with, but he kept everything being a toolmaker). What I didn't understand back 15 years ago? We sold, to the scrap yard, about 200 lathe blanks...we had NO FREAKING CLUE...Yea...Blanks were from 1/16" all the way up to 1" square. If I knew then, what I know now....hindsight is 20/20. To this day I kick myself about that. Worse thing? My dad who was a Tool and Die guy didn't even realize it either. I think we were so overwhelmed with the sheer amount of stuff to plough through we just said "It has to go"... :(

[@martineastburn3679]

Try dressing the skinny edge of the chip cutter a but shorter on the first part. Help it into the slot and then bend up the other side to snap the chip. Just an idea.

[@jean-francoisgrenier4947]

Well....in 12:46 minutes you just made my day :) thanks many times for that really useful video! Not sure it will be a success story the first time, but like you said HSS tool bit are cheap...just like me ;)

Hola meu amigo,show de atras de show seu trabalho me inspira a aprender este trabalho que considero verdadeira arte!Minhas saudações do Brasil!Joia

[@cav89-]

I loved it. And was amazed by the difference in the finish cut. But i was just wondering: besides creating a slope where the chip can go down and then curl up and break, the channel also introduced a significant amount of back rake, which the non-chip breaker tool visibly misses. As long as the doc is about the same or larger than the top face’s flat plateau before the downslope, that downslope is effectively the tool back rake. And aluminum likes a lot of back rake right? Thanks a lot for your vids and sharing this knowledge, your content is awesome! Best wishes and stay safe!

[@markgrevatt4867]

Thanks adam

[@JCMakerspace]

Some pretty interesting information. Thanks

[@railfan439]

Adam: Problem I have been seeing is when taking a .005 or .010 finishing pass on aluminum. That gives a birds nest almost every time. Thanks for the video.

[@AllThingsMech]

Tough to avoid that with such a light pass on aluminum...I run into the same issue occasionally. Especially with 6061, it's so soft it spins off like fishing line at .005, even with a chip breaker. You have to use sharp tools and take the heaviest cut you can without blowing your tolerance, not much else can be done.

[@jrneff9773]

I pretty good on the mill 30yr fab shop welder still only 43yrs young the lathe I struggle with I bought a full set of brazed pre ground bits turning 1018 cr spider web action our shop at the time wasn't into retooling old shop can you take a brazed tool bit to do the same that would be a nice lesson

[@charlescartwright6367]

Yes you can, use a green stone for the carbide, but the procedure is the same. The only limitation I can think of is the carbide is thin so regrinding the chip breaker may not work, depending on what you are doing. I have tools ground with the chip breaker optimized for different materials and keep them for that. Speeds things up too. I use a Dremel tool for the chip breaker grinding, but that is my preference.

[@BaileyFarming]

You went straight up Ave/this old tony on us in this one!
