The Freud 70-104 – 25/64" Key Hole Bit is the perfect solution for creating hidden keyholes for hanging pictures, plaques, and shelves. With a 25/64" diameter and 1/4" shank, this clever bit features a two-stage cutting design: the larger diameter end bores a hole for the nail or screw head to enter, while the smaller diameter allows space for the nail or screw shank, creating a completely concealed fastener. Crafted with TiCo Hi-Density Carbide, this bit ensures exceptional durability, offering long-lasting sharpness for smooth, clean cuts in hard and soft woods, plywood, and composites. The Freud Perma-SHIELD® Coating helps prevent heat buildup and pitch accumulation, ensuring a longer bit life and superior cutting performance. With a maximum RPM of 24,000, the Freud 70-104 bit is designed for high-speed cutting, making it suitable for CNC routers, hand-held routers, and table-mounted routers. Whether you're a professional woodworker or a DIY enthusiast, this bit ensures precise, hidden fastener cuts for hanging items with ease.
