Tool 100i313M030A

Steel work beats up sharp corners. Especially in interrupted cuts where the edge catches and releases thousands of times per minute. The 100i313M030A addresses this with a deliberate R0.03" corner radius that distributes impact forces across more carbide.

Four flutes keep chip load consistent through each rotation.
When you're face milling steel or running side cuts in iron, that consistency translates to predictable tool life.
The edge wears evenly instead of developing hot spots that accelerate failure.
TiAlSiN coating adds thermal barrier properties without building up thickness that would dull the edge geometry.
The coating stays put in titanium and nickel alloys where heat cycling typically causes coating adhesion problems.
At 0.3125" cutting diameter, this size handles detail work in tougher materials where smaller tools would snap.
