The countersinks in these sets are for use with most metals in addition to plastic and wood. They attach to a drill bit (sold separately) you can drill and countersink holes in one step. They attach to the drill bit with two set screws and the position can be adjusted for different screw lengths. The 82° countersink angle is compatible with the profile of flat- and oval-head inch screws.

Optional collar (not included) controls the cutting depth of your countersink. It attaches with two set screws.

Fasten differently sized screws with these sets. They save you the effort of switching three separate bits in and out of a power tool, instead letting you flip between a countersinking drill and a screwdriver bit with a single hand. You can also attach your own countersinking drills and screwdriver bits as long as they have a 1/4” hex shank.

Countersinking drills have an 82° angle, allowing inch-sized flat- and oval-head screws to sit flush with the surface.
