Solid Carbide Chatterless Countersinks - 3 Flute - 100 Deg - 7/8 X 1/2 X 3 - HTC 36669

7/8" 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 7/8" cutting body on a 1/2" shank, 3" 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.
