100 Series

Tool 100i625M125A

Corner wear kills consistency faster than any other failure mode. The 100 Series with R0.125" corner radius spreads cutting forces over a larger contact area, reducing the stress concentration that leads to premature corner breakdown in steel and iron.

Four flutes keep chip load balanced across interrupted cuts and full-width slotting operations.
When you're running production lots in 4140 or 1018, that balance translates to predictable tool life from the first part to the last.
The TiAlSiN coating adds thermal barrier protection during extended runs in tougher alloys like 17-4 stainless or Inconel, where heat buildup would otherwise accelerate wear.
The radiused corner also improves surface finish on profiling operations.
Less stress concentration means less chatter, and less chatter means fewer secondary operations to hit print dimensions.
