Interrupted cutting D2 tool steel is very difficult and unpredictable. D2 contains up to 14% Chromium and was designed to be used at 50-56 HRc. If the material is hardened to +60 HRc and not tempered very carefully, Chromium Carbide formation at the grain boundaries makes the material impossible to machine with interrupted cutting.
Rants and Raves regarding carbide inserts, cbn inserts, ceramic inserts, cermet inserts, and inserts in general. Occassionaly will take about nothing, and sometimes other cutting tools. Most of all a resource for information on cutting tools.
