7/16" cutting diameter, 5 flutes, single end, uncoated.
Ground from solid carbide. This tool cuts 7/16" diameter, runs a 7/16" shank, has 1" of flute and measures 2-3/4" overall. The flutes are cut at a 45° helix.
This is a rougher: the chip-breaking edge form cuts the cutting pressure and breaks the chip into short pieces, so it removes stock faster than a finishing tool at the same power.
Uncoated, so the edge stays as sharp as it can be ground — the usual choice for aluminium and other soft, sticky materials.
