Bit for a Twister Comm lathe
 

I recently purchased a used Twister Comm lathe and it arrived with a pretty dull carbide bit and a chipped diamond bit.

Does anyone know where the best place to purchase a new carbide bit for this lathe would be?

I've never used a comm lathe before so, I want to get a carbide bit for learning purposes before I spring for a nice new diamond bit.

You don't need a new carbide bit. You need a diamond file to sharpen yours.

www.mcmaster.com p/n 8168a13 coarse $19.22

or call 562-692-5911

you might want to pick up a couple of bits too.

p/n 3367a121 $3.42

You will need the file to put a tip on the bit, they come with the correct angles but the tip is rounded.

If I remember correctly the twister lathe cuts from the right to left. There is a guy on ebay that sells Diamond bit's for 49.00 I belive you would get a 4AR part # I have a xipp lathe and it cuts from right to left and uses the 4AL

Thanks for the help!

Hey Jack,

Why the course file and not the fine grit one?

Makes it easier to get a the tip onto a new bit. From what I hear, not much difference in the point with either file.

A bench top grinder with a "green" wheel does wonders too. Made specifically for sharpening carbide bits.
