240 Series

Tool 240i625C

The 240i625C is a 5/8" 2-flute end mill from the 240 Series, for high-speed machining in aluminum. Behind the 0.750" length of cut, the neck steps down to 0.605" out to 1.500" 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 0.010" smaller per side than the cut, so you can reach past the 0.750" of flute without the neck rubbing the wall.
A 0.004" corner radius holds up better than a sharp corner and leaves a 0.004" 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.
