100 Series

Tool 100i625M015A

Most shops know the sound of an end mill starting to go. The vibration changes first, then the finish starts wandering. The 100 Series is built to stay quiet longer in steel, iron, titanium, and nickel alloys.

Four flutes spread the cutting load across more edges, which reduces the stress concentration on any single point.
In side milling operations on tougher alloys, that distribution keeps each flute cooler and reduces the thermal cycling that leads to edge breakdown.
The TiAlSiN coating adds a thermal barrier that extends tool life when heat buildup becomes the limiting factor.
The R0.015" corner radius eliminates the stress concentration of a sharp corner while maintaining enough definition for clean part geometry.
Run-to-run consistency improves because the edge geometry stays more stable through temperature cycling.
