1/8" cutting diameter, 3 flutes, single end, TiN coated.
This tool cuts 1/8" diameter, runs a 3/8" shank, has 1" of flute and measures 2-7/8" overall. The flutes are cut at a 30° helix. The body is tapered at 3°.
Center cutting, so it can plunge straight down before feeding sideways.
The TiN coating adds surface hardness and lubricity over uncoated carbide or HSS in general-purpose work.
