Use these bits to create large, shallow recesses in wood, such as mortises for hinge leaves or locks. Made of carbide-tipped high-speed steel, these bits provide a longer tool life and faster cutting speeds than standard high-speed steel bits. They do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.

Lock-mortise bits create deeper recesses for bulky lock hardware to ensure doors close flush. They require an arbor (sold separately) to connect them to your router.
