Tool 100i750S030A

Corner wear shows up fastest where the cutting edge meets the workpiece at 90 degrees. Sharp corners concentrate stress, and stress accelerates wear in steel and iron cutting operations. The 100i750S030A addresses this with a 0.03" corner radius that distributes cutting forces across a broader contact area.

TiAlSiN coating adds thermal stability when cutting titanium and nickel alloys.
Higher aluminum content in the coating forms a protective oxide layer at elevated temperatures.
The kind of temperatures you see in aerospace materials where surface speed matters but tool life matters more.
Four flutes maintain even chip evacuation across the 0.75" cutting diameter.
In profiling and semi-finishing operations, that geometry keeps cutting forces balanced and reduces the harmonic vibration that leads to chatter marks on finished surfaces.
