200 Series

Tool 200m050LC

The 200m050LC is a 5mm 3-flute end mill from the 200 Series, for slotting and side milling in aluminum. The L in the part number means a longer cut: 15mm length of cut (3x diameter), for taller walls and deeper passes.

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.
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.
