100 Series

Tool 100i125LA

The 100i125LA is a 1/8" 4-flute end mill from the 100 Series, for profiling and finishing in steel, iron, titanium and nickel alloys. The L in the part number means a longer cut: 0.375" length of cut (3x diameter), for taller walls and deeper passes.

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 0.004" corner radius holds up better than a sharp corner and leaves a 0.004" 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.
