In a nutshell
The right choise for
With the Bosch wood drill bit with countersink, you drill pilot holes and countersink in a single operation. The 3 mm drill bit with a sharp brad point lets you start drilling precisely on mark without slipping. At the same time, the 16 mm countersink creates a clean recess so screw heads sit perfectly flush with the wood surface, preventing splitting during screw insertion. Whether you are assembling wooden furniture, fastening decking boards, or tackling interior construction, this combination bit saves you valuable time during repetitive drilling and fastening in hardwood, softwood, mdf, plywood, and chipboard.
