Hex-Shank Drill Bits with Guide for Countersunk Holes
The built-in guide has a beveled tip that fits into countersunk holes in hardware, such as hinges and latches, to center the bit. Guides are spring loaded; drilling pressure compresses the guide body and extends the drill bit into the workpiece. Insert directly into power screwdrivers, impact drivers, and other tools that accept a 1/4" hex shank. Also known as Vix bits.

Smooth-Finish Drill Bits for Wood
High-Speed Steel
Carbide-Tipped Steel
Bore clean, flat bottom holes in soft wood, veneer, and laminates. The center guide point prevents the bit from wandering. Also known as Forstner bits.
Carbide-tipped steel drill bits maintain their sharp edges longer than high-speed steel bits, and can cut through tough, abrasive material such as plywood, hard wood, and composites.

Fast-Cutting Smooth-Finish Drill Bits for Wood
Multiple outlining teeth bore clean, flat-bottom holes without chipping or splintering your surface—even when cutting across the grain. These bits are excellent for boring straight holes, overlapping holes, and holes on close centers in soft wood, veneer, and laminates. The center guide point prevents the bit from wandering. Also known as multispur bits or Forstner bits.
