Countersinking is the process of removing the inner edge of a drilled hole (i.e. chamfering) such that a countersunk woodscrew or bolt can sit flush with the surface.
Countersinking is best achieved by using Countersink Bits but for general DIY use, a Twist Drill twice the size of the drilled hole may be used to approximate.
