100C Series

Tool 100Ci750LA

The 100Ci750LA is a 3/4" 4-flute chipbreaker end mill from the 100C Series, for deep pockets and full slots in steel, iron, titanium and nickel alloys. The L in the part number means a longer cut: 2.250" length of cut (3x diameter), for taller walls and deeper passes.

The chipbreakers cut the chip short before long strands can pack the flutes, which matters in steel, where a packed chip is heavy and hard enough to break an edge.
Sonic sets the chipbreaker pattern so you can run a higher feed rate than a smooth flute and still get a good wall finish.
The end is center cutting, so you can ramp and plunge.
A 0.008" corner radius holds up better than a sharp corner and leaves a 0.008" 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.
