2-1/2" body 100° countersink, 3 flutes.

A countersink cuts the tapered seat that lets a flat-head screw finish flush with the surface. This one has a 2-1/2" cutting body on a 1" shank, 4-3/4" overall, ground to a 100° included angle.

The "chatterless" grind stays in contact with the work rather than skipping across it, which is what stops the tool from cutting a lobed, faceted hole.

100° is the aerospace standard for flush-head fasteners.
