Enlarge existing holes without changing their depth.

Bore clean, flat bottom holes in soft wood, veneer, and laminates.

Cut a variety of hole sizes with one bit—slide the blade to the desired cutting diameter marked on the bit and then tighten the screw. Use in a drill press; they are not recommended for use with handheld drills.

The screw point draws the bit in, quickly boring holes without applying pressure.

Also known as spade bits, these have a centering point and two cutting edges for boring holes in hard and soft wood.
