100 Series

Tool 100i188A

Small diameter work demands precision you can repeat. The 100i188A delivers that consistency in steel, iron, titanium, and nickel alloys through controlled geometry and protective coating.

Four flutes at 0.1875" diameter create frequent cutting contact that distributes heat and load evenly.
That distribution matters more in smaller tools where there's less mass to absorb variation.
The TiAlSiN coating adds a thermal barrier that keeps the cutting edge stable when heat builds up in confined cuts.
The R0.004" corner radius eliminates the stress concentration you get with sharp corners.
In interrupted cuts through work hardening materials like stainless or Inconel, that small radius prevents the edge chipping that kills consistency.
Each cut starts with the same edge geometry as the last.
