3-Flute SE 90° C'SINK HSS (LN = TiAlN-HC) - 1-1/4 X 3/4 X 2-7/8

1-1/4" body 90° countersink, 3 flutes.

A countersink cuts the tapered seat that lets a flat-head screw finish flush with the surface. This one has a 1-1/4" cutting body on a 3/4" shank, 2-7/8" overall, ground to a 90° included angle.

90° is the standard included angle for metric flat-head screws, and the common choice for chamfering a hole before tapping.
