4 flutes, single end, ball nose, extra long length, bright finish, uncoated.
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 bright, uncoated finish gives a direct cutting edge with no added edge radius from a coating.
