1/4" cutting diameter, 4 flutes, single end, square end, extra long length, AlTiN coated.
Ground from solid carbide. This tool cuts 1/4" diameter, has 1-1/2" of flute and measures 4" overall.
The square end cuts a flat floor with a sharp corner — slots, pockets, shoulders and side milling.
The extra length reaches into deep pockets and past fixturing that a standard tool cannot clear.
AlTiN is built for heat: stainless, tool steels and high-temperature alloys, especially with little or no coolant.
