Brocas para ranuras en T y de ojo de cerradura

A keyhole router bit routs a narrow slot that opens into a round pocket. This profile allows a workpiece to slide over a wall-mounted screw head and lock securely — an invisible, strong hanging method used for picture frames, mirrors, shelves, and cabinet backs. See the 1/2" shank keyhole bit for details.

A keyhole bit creates a slot that accepts a screw head for wall hanging. A T-slot bit creates an undercut channel — shaped like an inverted T — that accepts T-bolts or carriage bolts used in router tables, workbench jigs, and fixture-making. See the T-slot channel hinge bit for the latter.

A 1/2" shank keyhole bit runs with less vibration and is preferred whenever your router accepts it. The 1/4" shank version works well in compact routers and laminate trimmers where a 1/2" collet is not available.

Yes, but keyhole slots are more commonly routed handheld or with a plunge router, since you need to start and stop the cut at defined positions. If using a router table, ensure you have a solid starting block or use a plunge operation to enter the cut safely.

Depth depends on the screw head size you plan to use. The slot should be deep enough that the screw head seats fully into the round pocket and the workpiece sits flush against the wall. Always make a test cut in scrap to verify fit before routing the final piece.

These are relatively small-diameter bits, so a moderate-to-high spindle speed works well. Consult the bit manufacturer's recommended speed range for the specific diameter. Feeding too slowly causes burning; feeding too fast causes tear-out.

Yes. T-slot bits are commonly used to rout the channels in router table fences and MDF sleds that accept T-bolts for adjustable stop blocks and clamps. The T-slot channel hinge router bit is well suited to this application.

Yes, provided the shank diameter matches your router's collet. Infinity Tools offers keyhole bits in both 1/2" and 1/4" shanks to fit the widest range of routers. Always check collet compatibility before ordering.
