HS Countersink

HSS drill included. Quick-Change 1/4”

(6.3mm) HEX shank

When joining 2 pieces of wood using screws, it is essential to predrill and

countersink in order to achieve an esthetic and long lasting finish.

• Pilot hole - in the bottom board.

• Clearance hole and Countersink - in the top board.

The pilot hole diameter should roughly match the root diameter of the screw.

It can be slightly smaller for softwood.

The clearance hole should be slightly larger than the diameter of the threads.

For decking jobs, it is not usually necessary to pre-drill the bottom board,

as it will always be hidden from view.
