1/16" cutting diameter, 3 flutes, single end, TiCN coated.
This tool cuts 1/16" diameter, runs a 3/8" shank, has 1" of flute and measures 3-1/4" overall. The flutes are cut at a 30° helix. The body is tapered at 5°.
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.
