Outlet Lee Valley HSS Taper Drill Bits

The high-speed tapered drill bits are precisely ground on a CNC grinder and match the shapes of wood screws so that screw threads grip for the entire length of the screw. The drills are multi-purpose and will serve the needs of most woodworkers for both hard and soft woods. 2 3/4″ to 4″ long overall.

For softwood, you should always use a drill one size smaller than the screw calls for. Also available as complete drill bit/countersink/counterdrill units for a specific screw size – the unit includes a countersink/counterdrill, drill, stop collar, and a hex key – or in boxed sets with countersinks/counterdrills, stop collars and hex keys.
