Default 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

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.
