Questions about this item

What size tool holder do I need for the 5/16 in square shank?

A holder with a 5/16 in square pocket is required to fit the blank’s shank dimensions.

Can I use this M42 cobalt blank on the same lathe where I run high-speed steel bits?

Yes, it mounts in standard holders, but M42 cobalt tolerates higher heat so you can run faster speeds or harder materials.

How do I know the blank is cutting correctly after I grind the tool geometry?

Look for a continuous chip, steady cutting sound, and a smooth finish without chatter marks on the workpiece.
