countersink drill bit set

Used to create countersunk holes, chamfering via cutting processes after drilling with a carbide drill bit set on a drill press. Countersunk holes ensure the screw head sits flush, as the hole top is larger than the screw head. This prevents protrusion from the product surface. The main through-hole is drilled first, followed by countersinking with tools chosen based on the hole shape.
