200 Series

Tool 200i156LFC

Delicate aluminum features break down fast when chip load gets too aggressive. At 0.1563" diameter, every tenth matters. Too much load per tooth and you're looking at chatter, poor finish, or worse. The part moves before the cut completes.

This 200 Series end mill uses three flutes to distribute cutting load across more teeth, reducing individual chip thickness while maintaining feed rates.
The geometry works because lower chip load per tooth prevents the heat buildup that creates built-up edge on aluminum.
TiB₂ coating adds wear resistance for longer tool life in demanding passes without the adhesion issues you get with AlTiN on aluminum.
The R0.004" corner radius strengthens the cutting edge against chipping while maintaining sharp enough geometry for clean entry.
Built for aluminum, copper, and plastics where surface finish matters.
