Tool 100i375A

Most shops know the feeling. You dial in a program, get good parts, then watch performance drift over the next hundred pieces. The 100i375A addresses this with four flutes that distribute cutting forces evenly across each rotation.

TiAlSiN coating adds heat resistance without changing the geometry underneath.
In steel and titanium work, that thermal barrier keeps the substrate stable when cutting temperatures climb during longer runs.
The coating also reduces friction in the cut, which matters more in materials that tend to work harden under pressure.
The R0.006" corner radius prevents the sharp corner chipping that kills consistency in interrupted cuts.
Small radius, but enough to distribute stress at the corner where most failures start.
Four flutes keep chip load per tooth manageable even at higher feed rates.
