3/16" Spoon Cutter, center cutting, single end, 35° helix, 3 flutes, uncoated.
A spoon cutter is a center-cutting single-end mill with a gashed, spoon-shaped end, so it can plunge straight into the material and then feed sideways without a pilot hole. This one is ground from solid carbide and cuts 3/16" diameter on a 3/16" shank, with 9/16" of flute and 2" overall.
Stainless work-hardens the moment the edge stops cutting, so this geometry is ground to keep a positive rake and shear the chip rather than rub it.
The uncoated, polished flute leaves the sharpest possible edge — the usual choice for aluminium and other soft, sticky materials where a coating only adds edge radius.
