240 Series

Tool 240m160C

The 240m160C is a 16mm 2-flute end mill from the 240 Series, for high-speed machining in aluminum. Behind the 20mm length of cut, the neck steps down to 15.5mm out to 40mm from the tip.

Two flutes leave deep chip gullets, so chips clear at the feed rates and surface speeds high-speed toolpaths run.
Run it on trochoidal and high-efficiency toolpaths, where radial engagement stays low and spindle load stays steady.
The end is center cutting, so you can ramp and plunge.
The neck is 0.25mm smaller per side than the cut, so you can reach past the 20mm of flute without the neck rubbing the wall.
A 0.1mm corner radius holds up better than a sharp corner and leaves a 0.1mm fillet where the wall meets the floor.
TiB2 resists aluminum sticking to the edge, so you can run higher speeds and feeds than with an uncoated tool.
