13/32" cutting diameter, 2 flutes, single end, ball nose, TiN coated.
Ground from solid carbide. This tool cuts 13/32" diameter, has 1" of flute and measures 2-3/4" 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 TiN coating adds surface hardness and lubricity over uncoated carbide or HSS in general-purpose work.
