Description

This set of Tapered Countersink Drill Bits with stop collars and no-slip shafts will be perfect for any job where you need recessed screw heads. The fully adjustable tapered HSS steel drill bits are made to mimic the shape of the screw shaft to give your screws more holding power in the wood.
