5/8" cutting diameter, 4 flutes, single end, square end, uncoated.
Ground from solid carbide. This tool cuts 5/8" diameter, runs a 5/8" shank, has 1-1/4" of flute and measures 3-1/2" overall.
The square end cuts a flat floor with a sharp corner — slots, pockets, shoulders and side milling.
Uncoated, so the edge stays as sharp as it can be ground — the usual choice for aluminium and other soft, sticky materials.
