These Snappy Countersinks with Straight Drills are for modern woodscrews with straight shanks. Use these countersinks to drill the pilot hole and countersink or counterbore in one, easy step. A large, hardened set screw holds drill bit securely to prevent bit slippage. You can easily adjust the drill bit for proper pilot hole depth. Uses standard-size drill bits.
These countersinks are made from alloy steel and hardened to cut hardwoods and composites. They can be re-sharpened for a long cutting life. 82° countersink angle allows screw heads to fit tight and flush to the surface. 1/4" hex shank fits our Quick Change Chuck, impact drivers, and all conventional drill chucks.
