11/32" cutting diameter, 4 flutes, single end, ball nose, extra long length, Sky Coat coated.
Ground from solid carbide. This tool cuts 11/32" diameter, runs a 3/8" shank, has 1-5/8" of flute and measures 4" overall.
The ball nose leaves a radiused bottom, which is what you want for 3D contours, fillets and mould surfaces rather than flat floors.
The extra length reaches into deep pockets and past fixturing that a standard tool cannot clear.
The Sky Coat finish is intended to support lubricity and wear resistance in milling applications.
