Tool 150i625L030A

Edge chipping in harder steels often comes down to heat and shock loading at the cutting edge. The 150i750M030A addresses both through geometry and coating selection.

Five flutes distribute cutting forces across more contact points, reducing individual tooth loading while enabling higher feed rates.
The TiAlSiN coating adds thermal barrier properties that matter when machining steel, iron, titanium, and nickel alloys where cutting temperatures climb quickly.
Heat buildup is the enemy of tool life in these materials.
The R0.03" corner radius strengthens the cutting edge compared to sharp corner geometries.
That small radius distributes stress over a larger area, reducing the likelihood of microchipping during interrupted cuts or when entering harder sections of the workpiece.
Semi-finishing and finishing operations benefit from the improved surface quality that comes with controlled chip loading.
