1/4" cutting diameter, 3 flutes, single end, TiCN coated.
This tool cuts 1/4" diameter, runs a 3/8" shank, has 3/4" of flute and measures 2-1/2" 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.
TiCN is harder than TiN and holds up better in abrasive materials and higher feeds.
