Movement in bit when turning

[mikey]

Right you are Mikey. Thanks for the tip about the depth of cut needs to exceed the nose radius. I had forgotten that rule.
I am using HSS more on finishing and more delicate work but you can't beet quality carbon inserts for removing a lot of material.
They like aggressive feed rates too for good chips and finish. IMHO

There will always be a need for both kinds of tooling, as well as the need to know how to use them effectively. Just slapping either one in a tool holder doesn't automatically make the tool cut well. There is a whole other side to cutting tools if you just explore their geometry and lead angles, and this applies to HSS and carbide. So much more can be accomplished if you are just willing to turn your tool post a few degrees ...
