100 Series

Tool 100i250A

Quarter-inch work gets tight fast. The 100i250A handles those confined spaces where larger tools can't reach, maintaining the same four-flute stability that defines the series.

TiAlSiN coating extends tool life in steel and titanium applications by reducing heat buildup at the cutting edge.
The aluminum content in the coating acts as a thermal barrier, keeping temperatures manageable during extended cuts in demanding alloys.
Four flutes still distribute the load evenly, but now each cutting edge stays cooler longer.
The R0.006" corner radius prevents chipping on entry and exit, particularly important at this diameter where edge strength becomes critical.
In slotting operations on steel or finishing passes on titanium components, that small radius maintains edge integrity through repeated contact cycles.
