This is a boring bar I made to replace a carbide boring bar that broke during a project. It has a round hole to hold the square HSS bit.

you may want to care about toolbit height center and of course the cutting angle when sharping it.

Do you think instead of using a square tool bit and to use round blank would work as well? I've been thinking to give a second life to the broken drill bit, and milling end bit. I am not sure if I should fastened by a screw, or threadlock it.

@SoatMon 7 жыл бұрын

That would probably work pretty well. The set screw may not hold very well since the bit will be round and hardened but I would sure try it. Let me know how it works out. Thanks for watching!

I can conform that it will work! I had a bunch of old 1/4 hss drill bits and use them now exclusively for my shop made boring bar. I did grind a flat spot on the bits where the set screw meets. BTW I don't have a mill so I put the boring bar in the lathe and drill bits in the lathe chuck. Fed the boring bar into the bit at the desired angle. Thanks for posting these videos!

Hi I enjoyed the tutorial, thanks. May I ask, why you drilled the tool holding hole at 45°? Why not drill at 90° to the bar? Thanks again. Stuart

@goward3 8 жыл бұрын

+Stuart York You could certainly drill it 90 degrees, I was just wanting the bit to be able to reach the bottom of a blind hole. If that was not a concern, 90 would be easier. Thanks for watching!

@LittleshopofFredrik 8 жыл бұрын

Normally it´s because with a 90deg bar you would not be able to go all the way to the bottom of a hole you want to bore. With a 45deg bar you can move the tool bit out to go past the end of the bar.

Okay. Nice. Wondered at first how you would end up with a square hole for the tool. Set screw holds it firm & square. Got it. Interesting.

Doug Bourdo you can use a broken taps or end mill or twist drill

May i know what is the material of the boring bar?? Is it the same material with the tool bit?

@SoatMon 4 жыл бұрын

The boring bar is an unknown steel from my scrap bucket. The tool bit is High Speed Steel.

How do you advance the tool to bore bigger?

@SoatMon 7 ай бұрын

It's used in a lathe so you move the cross slide out to enlarge the bore.

@stewartfrye Жыл бұрын

Your tool geometry is off, the leading edge of your tool bit is forward of the centerline of rotation, when you drilled the hole on center, it should have been drilled 1/2 cutter thick behind center line of rotation, you could grind enough (1/2) your tool bit back and it would cut better then.

@patkirk960 Жыл бұрын

You don't strictly HAVE to be on centre line when boring, you can cheat and grind both rake and clearance to suit. Tools like this are often used to get out of a 'fix' when you have no other available.

You didn’t demo the ding dang thing!? Don’t you think that would be the main objective? Proof of concept, and prototype? Thanks for the how to justify spending 5g’s on a lathe to my no longer amused and hard to impress soon to be ex wife tutorial!
