110 Series

Tool 110i500A

The 110i500A is a 1/2" 3-flute end mill from the 110 Series, for slotting and profiling in steel, iron, titanium and nickel alloys. Length of cut is 1.000" (2x diameter), the stiffest option in the 110 Series at this size.

Three flutes leave more chip room than a 4-flute and more edges than a 2-flute, and Sonic designs the flutes to clear chips in slotting.
In titanium and nickel alloys, that extra chip room lowers the heat load on each pass.
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.
