1/2" cutting diameter, 2 flutes, single end, ball nose, long length, TiN coated.
Ground from solid carbide. This tool cuts 1/2" diameter, has 2" 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 long flute gives more usable depth than a standard length.
The TiN coating adds surface hardness and lubricity over uncoated carbide or HSS in general-purpose work.
