1/2" Spoon Cutter - Ball End. Single End with 35 Degree Helix. Shank OD 1/2" - LOC 1-1/4" - OAL 3" - 3 Flutes for Stainless Steel machining. AlTiN Coated

1/2" Spoon Cutter, ball end, single end, 35° helix, 3 flutes, AlTiN coated.

A spoon cutter is a single-end mill with a gashed, spoon-shaped end. This one is ground from solid carbide with a full-radius ball nose, and cuts 1/2" diameter on a 1/2" shank, with 1-1/4" of flute and 3" overall.

Where the rest of the spoon cutter line runs a 45° helix for aluminum, this series runs 35° with a third flute. The lower helix angle puts more steel behind the cutting edge and the extra flute spreads the load — the combination HTC specifies for stainless steel.

The AlTiN coating forms an aluminum-oxide layer under heat, which is what lets it hold up in the high temperatures stainless generates at the edge.
