Hi, I recently bought a used Hudy lathe and would just like to know whether I can identify whether it has a diamond bit or a carbide one. The bit is also made by hudy if that helps.

Thanks,
Martin.

a diamond bit has a dark crystal like object at the tip area.

yes, and generally a carbide bit has a flat, gray surface

If it is a Hudy tip....look at it with a magnifying glass..the diamond tip will look as if it is "molded" to shape.

An even easier way is to see if the tip looks like it has a seperate piece of metal "stuck" on the main stem. You only get the diamond bit at the very end...the rest of the cutter is made from a diferent material!

Thanks for the help guys. My bit has a grey surface and than a dark/black surface at the very tip. Is this the diamond bit? Is the the hudy carbide bit all grey?

If this is your first Com Lathe, then the best way to tell a Diamond bit is if it breaks the first time you use it. Yep it's a Diamond bit. I know alot of experienced racers that prefer Carbides bits to Diamond for that very reason. Too easy to break a Diamond bit.
