Kreg KHI-BIT Hinge Jig Bit, Concealed

The 35 mm concealed hinge bit makes it possible to bore clean, perfect holes for concealed hinges. The bit is a direct replacement for the bit thats 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 tear out. 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.
