Drill Bit Countersinks
Available12 products
Drill bit countersinks can drill and countersink a hole in one step for maximum productivity. Drill bit countersinks produce a chamfered hole with a tapered opening that allows screws to install flush with the surface of the workpiece for a finished look. This helps prevent the workpiece material from swelling when a screw is installed in the hole and tightened down in woodworking and metalworking applications. They can also be used to debur holes for a smooth finish.
Shank Type - Machining
Drill Bit Countersinks
Drill bit countersinks combine a drill bit and a countersink in one tool. The height of the countersink can be adjusted to suit the hole depth, and the drill bit can be replaced when worn. These tools create a chamfered hole with a tapered opening that permits screws to install flush with the surface of the workpiece for a neat appearance.
