set up dead rigid in a milling machine (Bridgeport or equal) will ream out the drill stub.
This new tool is a solid carbide endmill
that is targeted at machining hardened steels, those in the 48 to 62 HRc range, which means that the tool has specific applicability for mold and die applications.
The cutters are available in screw-on, endmill
, and shell mill style.
This grade is used for its FINISHRED IC300 endmill
