Single Point Cast Iron Boring Tool

[@jeffreyschmiedeck4254]

Bring back memories. When I first started out in a machine I operated a Hardige chucker where I had to grind my tools out of C2 cemented carbide.

[@lukaszrabiniak6307]

Hello Mr. wizard. Do you know that you behave like a high school teacher? For me personally its perfect. I love to eat new info and knowledge. And I am sure that loads of fans feel the same way.

[@oxtoolco]

Hi Lukasz, Thanks for the comment and compliment. I remember my high school metalshop teachers very well. Cheers, Tom

[@MyShopNotes]

Thanks for the tip on making the grinder more balanced. I had a bad vibration with a wheel once and just put the wheel aside because I didn't have a clue what to do.

[@oxtoolco]

Hey Steve, It works pretty good. I have gone from the grinder walking around on the bench to balance a coin on the tool rest by clocking the wheels. Time to dig those wobbly wheels out. cheers, Tom

[@johncoscia5258]

Yes indeed , we acknowledge your point . After all your point was made splendidly and is sure to be a handy addition in the toolco expert collection of points . But thanks for that video really , so I tried to emulate your craftsmanship with some success , My failure was the millng machine , don't got one , maybe one Christmas? The geometry was effective on the lathe, but I now realise why milling is preferred when boring cast barrels . Holding on tight actually did improve chatter but never again . Thanks again .

"Doesn't have to be mongo tight, you don't have to gronk on it" Tom has the best words ask anyone they'll all tell you.

[@oxtoolco]

Hey Mike, What's cool is everybody understands my weird language. Thanks for the comment. Cheers, Tom

[@vajake1]

Those were some really good tips concerning carbide. I didn't know not to cool carbide in water when forming a tool. I have done some internal boring and wondered why the tools that I formed did not produce good finishes. Now I understand much more! Thanks so much!

[@oxtoolco]

Hey Bob, Carbide cannot handle the same kinds of thermal shocks that high speed can. High speed is pretty bullet proof. Cheers, Tom

[@andymandyandsheba4571]

every time i changed a grinding wheel some git had always put them on with a bloody big leaver bar and took me ages to get the nut shifted i am glad you mentioned about not tightening the nuts to tight good video tom long time since i use a boring bar to bore a block out enjoyed it

[@oxtoolco]

Hey Andy, I think that guy worked at our shop once........ Cheers, Tom

[@BoffinGrusky]

As usual Tom, every time I watch one of your videos, I learn at least one new thing. This one was good for at least 3 or 4 new things!! Thank you for posting!!

[@oxtoolco]

Hey Johnny, Just keep watching..... Thanks for the comment. Cheers, Tom

[@KnolltopFarms]

Ton o 'fun with Tom's barrel of puns! "That's kind of boring"..."You guys get the point"...All too funny when you don't even realize you're making them! I really liked this one, as I didn't even know you could regrind carbide tools, sweet! Thanks for the share. Aloha...Chuck

[@oxtoolco]

Hey Chuck, Get that bench grinder of yours tuned up. We will get you a nice silicon carbide wheel so you can grind your own carbide tools. Cheers, Tom

[@ckvasnic1]

Cool. Thanks for sharing your time and tallent. I'm bummed that someone beat me to telling that was a boring video. All the best. Chuck.

[@miles11we]

didnt even think about balancing wheels like that. iv always been so fixated on the individual wheel, not how they are in relation to eachother. ima give that one a go, thanks

[@ggs191]

To extend your idea of marking the edge of the wheel as a witness mark, I use the center head of a combination square to draw a line through the wheel center across its full diameter. This line can also then be used as a reference to more easily set the tool rest to some particular angle or orientation relative to the center/tangent of the wheel.

[@oxtoolco]

Hi ggs, Now that is a great idea! I like it and its going in my toolbox. Thanks for the comment and sharing. All the best, Tom

[@billdoodson4232]

Working my way through the back catalogue of videos and came over this one. Have to say that I can't think to have seen anyone listing THERMITE as something to be doing on the old whiteboard.

[@billdlv]

Thank you very much Tom for answering my questions and helping me on this project. The video was very helpful I can tell my tool bit is not ground properly from the surface finish, and the chips I'm getting are more granular.

[@oxtoolco]

Hi Bill, Get your hands on a green wheel. I think it will make a big difference in your carbide tool grinding. Cheers, Tom

[@ExtantFrodo2]

I don't know if you mentioned this in your video, but when deciding on the amount of relief to provide, it should be made on the original inside diameter rather than the final inside diameter. BTW, I've been watching this videos almost non-stop since I discovered them a few days ago. Great work!

[@oxtoolco]

ExtantFrodo2 Hi Frodo, Thanks for the comment. You are correct in that the clearance is determined on the min bore. Cheers, Tom

[@pierresgarage2687]

Hi Tom, Great tip about balancing the grinder. Sometimes I use diamond wheels for grinders, those wheel are made for ceramics but they do the rough on carbide tools... Just use the continuous ones NOT the serrated ones. Thanks again for showing all that stuff, Pierre

[@oxtoolco]

Hi Pierre, Normally I prefer diamond for doing carbide tools as well. It was an opportunity to show the work on a grinder that most folks have. Thanks for dropping by. ----Tom

[@craigspakowski7398]

I'm going to have to try some of your grinding pointers. I am having a heck of a time with chipping my brazed carbide tools.

[@oxtoolco]

Hey Craig, Just backing the tool over the work can chip a carbide tool. Specially in something like stainless where there is more tool pressure and more springback in the tool. Cheers, Tom

[@craigspakowski7398]

oxtoolco Or on a lightweight flexy machine like a SB9" Hmm I'll have to do a bit of testing. Thanks for the ideas.

[@swarfrat311]

Hey Tom, Thanks for the interesting video! (I didn't get bored at all!) You are a great and knowledgeable instructor. I have learned a lot from you and others on KZbin. Everyone has their own take on a problem, so I get a variety of methods so that I may form my own knowledge base. Thanks again, Mr. Wizard! Regards, Oxen Dave . . . waxing philosophic

[@oxtoolco]

Hey Dave, Thanks for the compliment. Cheers, Tom

[@k5at]

Tom, Thanks for the boring video! Hi Hi Your footage of tool grinding is outstanding! Thanks for sharing.

[@oxtoolco]

Hey Herb, You can even watch me grind my fingernails..... All the best, Tom

[@RandallMoore1955]

Hi Tom. Thanks for the tip. Just dropped in for a tune up, Have a good one.

[@oxtoolco]

Hi Randy, Thanks for the comment. Cheers, Tom

[@CompEdgeX2013]

Havent bored a cylinder in years now that most everything is Nikasil but usually used the lathe for oversize then the Sunnen for finish. Havent yet tried the boring head for the job. Keep it in mind though in case the need arises.....;-) Colin

[@oxtoolco]

Hey Colin, This one is an inline four cylinder engine. He has it all set up on the mill. I used to have a great Sunnen hone that I did Kart engines on. You could split tenths with that thing all day long. Cheers, Tom

[@CompEdgeX2013]

Ya, still lots of bike engines running iron. they havent caught up to the snowmobile tech. ;-)

[@kerrymccall5003]

Hi Tom. I'm a woodworker but really enjoy the joking and goofing that you do with Adam and clan. Is there a vibration or wobbling in you turret? Looks like I'm seeing some movement. Keep the videos coming!

[@oxtoolco]

Hi Kerry, Don't think so. I might have had the tripod touching the mill. Maybe it picked up a vibration from it. Cheers, Tom

[@Max_Marz]

Aw man that eccentric gear is nice. Wish I had a table piece like that :(

[@doubleboost]

Hi Tom A very informative video I see you have developed the "heat resistant" fingers as well Just finished reading your book (for the third time) You should be getting a package this week Regards John

[@oxtoolco]

Hey John, Glad you like the book. It might save you from making all the mistakes it took to figure all that stuff out. Looking forward to some of your packaging. Cheers, Tom

[@lukaszrabiniak6307]

oxtoolco Any chance for a link to the book ( amazon link to a hard copy ? )

[@yagneshsiddhapura]

Hey Tom it is very interesting that I have seen some rough boring head with two cutting edge and even single point boring head (using carbide inserts) are have cutting edge little offset then center line of work piece could you explain why is that so !!!

[@austin3538]

nice work thanks for showing Tom

[@russhellmy]

Great video as usually, except this one was more boring lol. Keep them coming.

[@bufford14]

What would have happened to the Norton stone if you had of ground steel with it. Would it be like grinding on a stone just for aluminum. I learned a great lesson one time by grinding steel with a grinding wheel only for aluminum, I ruined it. It had gumed up aluminum all in it. Had to use the touch up wheel a while to get it back to where it should be. Interesting Video Tom, I enjoyed it. See ya Mark

[@oxtoolco]

Hi Mark, In the case of grinding steel on a wheel for aluminum the only downside is the wheel breaks down really fast. This is why you can use them on aluminum and brass as they break down and the material never has a chance to load the wheel. In the opposite case if a aluminum oxide wheel was loaded with aluminum I would dress it with a diamond to remove the loaded layer and then you could use it again. Cheers, Tom

[@aaronkokesch3593]

Hey Tom Have you ever tried using a dremel for creating chip breakers instead of the edge of the grinding wheel?? I have been thinking of trying it myself for my cutting tools since all the wheels for the bench grinders in class seem to have a 1/4- 1/2 radius on them. Do you have any tips on what I'm looking for geometry wise when I create a chip breaker??

[@oxtoolco]

+Aaron Kokesch Hi Aaron, I have tried it. It works pretty well but you have to be super careful not to slip over the cutting edge when you are using a hand held tool. Thanks for the comment. Cheers, Tom

[@MaulTechATV]

Thanks again for the great video and explanation. Going to have to buy a silicon carbide grinding wheel now. My aluminum oxide doesn't stand a chance to the carbide that I rarely grind! I've tried boring motorcycle cylinders on my mill but I was getting way too much chatter so purchased a boring bar instead. I'd love to see your boring tool setup, especially how you mounted that shank in your bar. Did you make that? Andy Maul

[@oxtoolco]

Hi Andy, The bar that was in the boring head is homemade and just basically a heavy duty extension. That boring head holds a one inch shank but I wanted a bar that had a slot and multiple set screws so I could hang a decent sized tool bit out a little at the end since that head does not offset that much. Cheers, Tom

[@MaulTechATV]

oxtoolco Thanks for the comment Tom. Sounds like a good project for me to tackle some weekend.

[@1NRG24Seven]

Would a small pair of vice grips give you more control and help keep your fingers away from wheel and keep one from getting burned on hot tool being ground?

[@oxtoolco]

Hey Seven, It would help with the heat but complicate the grinding. When the tool is clamped in something hard and metallic like a vise grips it bounces more when you touch the wheel. Your hand and fingers damp out a lot of the vibration when grinding tools. Cheers, Tom

[@1NRG24Seven]

oxtoolco Makes sense ....was just cringing seeing you grind your fingers:)

[@imduncanmajunkin]

Love your vids, watch em all. Just wondering why you don't buy an awesome grinder like Adam has. Bigger is better. They are all over craigslist.

[@oxtoolco]

Hi Todd, I like to wait and ambush my prey. Been lurking looking for the right deal on a larger grinder. Not high on the priority list compared to some other machines. Thanks for the comment. Cheers, Tom

[@Tadesan]

Big honkin fly tools are cool

[@cgis123]

Another great vid Tom !!! May I ask what type/brand the boring head is. Thanks again Matt

[@oxtoolco]

Hey Matt, Its an older Criterion head. It hold one inch diameter bars. Cheers, Tom

[@cgis123]

Thanks for the fast response Tom. I the biggest one I have will hold a 20mm bar and has 3'' adjustment. I'll have to look in the morning for the brand name on it as my memory is failing me at the moment, but I'm pretty sure its American made and starts with the letter ''B'' anyways ill let you get back to making the next video instalment. Regards Matt

[@oxtoolco]

Matthew Gischus Bokum? ---Tom

[@cgis123]

Sorry Tom, there will be a bit more of a delay before I can get back into the shop to look. We have had so much rain here I would have to wade through 2 foot deep water to get to the shop. I've had a storm water drain block up and flood the yard. So I have been getting very wet digging up drain lines trying to get the water to drain.....

[@cgis123]

oxtoolco Ok, sorry for the delay Tom. As it turns out I lied :-0 My large 3'' boring head is a Spanish made HORMA... I picked it up second-hand a few years ago, actually from memory it was thrown in by the seller when I bought my 12'' Mecca ( I think that's the way its spelled) rotary table. Both the rotary table and the boring head had barely been used and I payed about one 20th of what they were worth... anyway that's the mystery of the boring head name solved.. Have a great day.. Matt

[@pvtimberfaller]

Why didn't you shim behind your toolbit?

[@dogbuggy32]

got my eye out for a diamond super wide I likey

[@thoperSought]

got a 'clinique for men' video ad before this video... apparently, they don't do *any* targeting on those things...

[@oxtoolco]

All the guys around here don't have much hair to take care of. When I get a haircut I ask for a haircut with a hole in it. cheers, Tom

[@thoperSought]

oxtoolco thanks Tom, I couldn't stop laughing

[@devilmastah]

the holder looks like it has some runout ?

[@fuzzy1dk]

that's how you adjust the boring diameter

[@devilmastah]

That was kind of stupid now i think of it. Totally forgot about that

[@oxtoolco]

devilmastah Pause before hitting reply..... Just kidding. I actually adjusted it back to center before I shot the video. That boring head can get a good vibration going. Cheers, Tom

[@FlyingWingless]

Yawn, sure is a boring tool! -but an awesome video. Thank you!!!

[@repalmore]

Kinda boring? Setting the bar a little high. Puns completely intended.

[@oxtoolco]

Knnack Knaack, Knaack, Cheers, Tom

[@repalmore]

oxtoolco There you go, you've got the Knaack of it! ;o)
