Choose an option to view item availability.
These combination units are specifically designed for woodworkers. 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. 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.
Units are available for screw sizes 5, 6, 7, 8, 9, 10, 12 and 14.
Components can be purchased individually. We also offer multi-size box sets.
