Tool 150i375L004A

Chatter and premature wear are common problems when finishing harder steels at production speeds. The 150 Series addresses this with five flutes that distribute cutting forces more evenly.

Five flutes reduce chip load per tooth at any given feed rate, which keeps cutting temperatures manageable in steel, iron, titanium, and nickel alloys.
The TiAlSiN coating adds thermal barrier properties and maintains sharp edges longer in these materials.
Heat buildup is the primary failure mode when finishing harder grades, so both the flute count and coating work together on temperature control.
The 0.03" corner radius strengthens the cutting edge and reduces stress concentrations that lead to chipping.
This geometry performs well in semi-finishing and finishing operations where surface quality matters more than maximum material removal rates.
