100 Series

Tool 100i250S030A

Quarter-inch work calls for balance. Too aggressive and you're chasing chatter. Too conservative and cycle times stretch. The 100 Series splits that difference with geometry that prioritizes stability over peak metal removal rates.

Four flutes at 0.25" diameter create consistent chip evacuation without overloading the spindle.
In steel and iron roughing operations, that balance translates to predictable tool life across different alloy compositions.
The TiAlSiN coating adds thermal barrier protection during interrupted cuts where heat cycling typically degrades uncoated edges.
The R0.03" corner radius reduces stress concentration at the cutting edge.
Sharp corners chip under load variations.
This radius maintains edge integrity through entry and exit transitions in profiling work.
Steel, iron, titanium, and nickel alloys respond well to the consistent engagement this geometry provides.
