The Bahco 9626 Series Combination Auger Bits are made from hardened tool steel and lacquered for rust protection. Spirals with Levin pattern. Can be used in both electric power drills and hand braces. Part of the tang has a hexagonal shank (15mm long) for a firm grip in the chuck, suitable for hand braces.
The threaded tip moderates a self-feed when using a power drill, but still sufficient self-feed when used in a hand brace. Ideal for quick precision cutting with all types of wood.
