Default Identifying Diamond bits?

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.

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?

Default Diamond bit identification

rcpilot;

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.

Pops - I used the Paint program on my computer. I resized it until it fit the size requirements
