Freud 70-104 Keyhole Router Bit 25/64 in 1/4 in Shank

Product Description

The FREUD 70-104 is a carbide keyhole router bit designed to cut keyhole slots in wood and wood composite materials for flush wall-hanging applications. With a 25/64 inch cutting diameter, a 1/4 inch shank, and a 7/16 inch cutting length, this bit produces the teardrop-shaped channel that accepts screw or fastener heads. The total length measures 1-5/8 inches. Carbide construction provides durability and extended edge retention compared to high-speed steel alternatives. This bit is sized for use in standard 1/4 inch collet routers common in millwork and cabinet shops.

The 70-104 is suited for residential and light commercial millwork applications where panels, shelving, picture frames, or cabinet backs need to hang flush against a wall without exposed hardware. It is used by carpenters, cabinet installers, and finish contractors working with plywood, MDF, hardwood, and similar sheet goods. The bit routes the entry hole and slot in a single pass with the correct geometry to accept a standard screw head.

Installation Notes

Installation is performed by a carpenter or woodworker using a handheld router or router table equipped with a 1/4 inch collet. Secure the workpiece fully before routing and set router depth according to the substrate thickness and desired slot depth. Do not force the bit through material at excessive feed rates, as this can cause carbide edge chipping. Follow standard workshop safety practices including eye protection and dust collection.
