100 Series

Tool 100i500X015A

The 100i500X015A is a 1/2" 4-flute corner radius end mill from the 100 Series, for profiling and finishing in steel, iron, titanium and nickel alloys. The X in the part number sets the length: 2.000" length of cut (4x diameter).

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.
Extra flute length costs you stiffness, so pick the shortest length that clears the wall.
The 0.015" corner radius leaves a 0.015" fillet where the wall meets the floor, and it holds up better than a sharp corner.
The TiAlSiN coating is built for heat: it holds up to 1000°C and its low-friction surface cuts down wear.
