200 Series

Tool 200m050LFC

The 200m050LFC is a 5mm 3-flute end mill from the 200 Series, for slotting and side milling in aluminum. The F in the part number means a reduced neck behind the flutes, so you reach 31mm from the tip, deeper than its 15mm length of cut.

Three flutes give you more cutting edges than a 2-flute end mill and still leave the chip room aluminum needs.
Sonic designs the flute to clear chips in slotting.
The end is center cutting, so you can ramp and plunge.
You clamp a 6mm shank, stiffer than a 5mm 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.
TiB2 resists aluminum sticking to the edge, so you can run higher speeds and feeds than with an uncoated tool.
