Discount Lee Valley Drill Bit/Countersink/ Counterdrill Sets

These combination units are specifically designed for woodworkers. The high-speed steel 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. Our countersink/counterdrill units (unlike most others) are hardened; they are also sharpened after hardening. Used in combination with a stop collar, they let you set the unit for a wide range of screw lengths for everything from flush countersinking to a full 1/2″ of counterdrill.

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.

The set of five (for screw sizes 5, 6, 7, 8, and 10) contains five countersink/counterdrills, five taper-point bits, two stop collars ( 3/8″ and 1/2″) and two hex keys.

The set of all eight adds the drills and counterdrills for screw sizes 9, 12 and 14.

Both sets include a foam-lined plastic storage box with space for additional drivers or bits. Excellent value.
