Bore clean, perfect holes for concealed door hinges
The 35mm Concealed Hinge Bit makes it possible to bore clean, perfect holes for concealed hinges. The bit is a direct replacement for the bit that’s included in the Kreg Concealed Hinge Jig.

For clean, fast cutting, the bit features four carbide cutters—two main cutters that bore a flat-bottomed hole, and a pair of spur cutters that ensure clean hole edges free of tearout. The bit shank is sized to fit in the drill guide on the Concealed Hinge Jig, and the shank has a shoulder that perfectly positions a stop collar.
