Tool 100i188L015A

Most shops know the drill with small end mills in steel. They work great for the first few parts, then edge chipping starts and surface finish goes downhill fast.

The 100i188L015A addresses that reality with TiAlSiN coating over solid carbide.
The coating extends tool life in harder steels where uncoated tools typically fail from abrasive wear.
Four flutes keep chip loads manageable even at the smaller 0.1875" cutting diameter, distributing heat and cutting forces more evenly than fewer-flute designs.
The R0.015" corner radius strengthens the cutting edge where chipping usually starts first.
That small radius eliminates the sharp corner that acts as a stress concentrator, particularly important when interrupted cuts are involved in steel and iron applications.
Consistent performance in steel, iron, titanium, and nickel alloys.
Solid carbide.
Made in the USA.
