Ryobi 4 Piece Countersink Drill Bit Set includes four gauge countersink drill bits and a hex key for creating recessed holes for fasteners.
The Ryobi 4 Piece Countersink Drill Bit Set is designed for making recessed and countersunk holes in timber using a drill. This set includes four gauge countersink drill bits (#6, #8, #10, and #12) along with a hex key for depth adjustments.

The bits are equipped with a ¼” hex shank, making them compatible with drill drivers, although they are not recommended for impact drivers.
