Tool 150i375M004A

Built-up edge formation kills surface finish in steel. The 150i375L004A addresses this with five flutes that distribute cutting load across more edges.

Lower chip load per tooth at equivalent feed rates reduces heat generation and minimizes material adhesion to the cutting edge.
The TiAlSiN coating adds thermal barrier properties that further reduce temperatures at the tool-workpiece interface, particularly useful when machining titanium and nickel alloys where heat buildup accelerates tool wear.
The R0.004" corner radius strengthens the cutting edge without sacrificing sharpness.
This small radius prevents chipping in interrupted cuts while maintaining clean entry into the workpiece material.
Five flutes work best for semi-finishing and finishing operations in steel, iron, titanium, and nickel alloys where surface quality matters more than material removal rate.
