100 Series

Tool 100m040A

The 100m040A is a 4mm 4-flute end mill from the 100 Series, for profiling and finishing in steel, iron, titanium and nickel alloys. Length of cut is 8mm (2x diameter), the stiffest option in the 100 Series at this size.

Four flutes are the standard geometry for profiling and finishing in steel, and Sonic shapes the flute form to clear chips.
The end is center cutting, so you can ramp and plunge.
A 0.1mm corner radius holds up better than a sharp corner and leaves a 0.1mm fillet where the wall meets the floor.
The TiAlSiN coating is built for heat: it holds up to 1000°C and its low-friction surface cuts down wear.
