110 Series

Tool 110m030LFA

The 110m030LFA is a 3mm 3-flute end mill from the 110 Series, for slotting and profiling in steel, iron, titanium and nickel alloys. The F in the part number means a reduced neck behind the flutes, so you reach 21mm from the tip, deeper than its 9mm length of cut.

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.
You clamp a 6mm shank, stiffer than a 3mm one, and get the reach from the neck.
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.
