1/4" End Mill HOG Mill Single End. Medium Pitch Knuckle Rougher. 25 Degree Helix. Chamfer Width .020" - Shank OD 1/4" LOC 3/4" OAL 2-1/2" - 3 Flutes - Uncoated

1/4" cutting diameter, 3 flutes, single end, uncoated.

Ground from solid carbide. This tool cuts 1/4" diameter, runs a 1/4" shank, has 3/4" of flute and measures 2-1/2" overall. The flutes are cut at a 25° 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.
