Tool 100i375M030A

Heat buildup kills consistency faster than anything else in steel work. The 100i375M030A handles this with TiAlSiN coating that forms a thermal barrier between the cutting edge and the workpiece. When you're pushing through 4140 or 316 stainless at production speeds, that barrier keeps temperatures stable where it matters most.

Four flutes spread the thermal load across more cutting edges, so no single edge carries excessive heat long enough to break down.
The R0.03" corner radius reinforces the cutting edge without creating a stress concentration that would fail under interrupted cuts.
In profiling operations on hardened steels, this radius maintains edge integrity through hundreds of linear inches.
TiAlSiN stays adherent at temperatures where uncoated carbide would start to crater.
The result is predictable tool life from part one through part fifty.
