Tool 150i500M006A

Chatter marks in harder steels often trace back to excessive chip load per tooth. The 150 Series addresses this with five flutes instead of the typical four.

Five flutes distribute cutting forces across more edges, reducing chip load per tooth at any given feed rate.
This keeps temperatures down and surface finish consistent in steel, iron, titanium, and nickel alloys where heat buildup degrades both tool life and part quality.
The TiAlSiN coating adds thermal barrier protection at higher cutting speeds while maintaining edge sharpness longer than uncoated tools.
The R0.006" corner radius strengthens the cutting edge against microchipping without significantly affecting corner sharpness in semi-finishing operations.
Best suited for semi-finishing and finishing passes where surface quality matters more than material removal rate.
