Tool 100i375S015A

Steel work puts heat into the cut. The 100i375S015A manages that heat through coating chemistry and edge geometry working together.

TiAlSiN coating creates a thermal barrier between the carbide substrate and the workpiece.
In steel, iron, titanium, and nickel alloys, this barrier keeps cutting temperatures from spiking during interrupted cuts and heavy side milling operations.
The aluminum content in the coating forms a protective oxide layer at cutting temperature.
A natural response that extends tool life in high-heat applications.
The R0.015" corner radius strengthens the cutting edge where chipping typically starts.
Sharp corners concentrate stress, but this radius distributes cutting forces across more carbide material.
Four flutes maintain the series' even chip load distribution while the radius keeps each cutting edge intact through longer production runs.
