Invisible Mounting: The Perfect Bit for Hidden Fasteners on Plaques and Custom Shelving

The Freud 70-104 Key Hole Router Bit is the clever solution for creating secure, fully concealed fasteners in your fine woodworking projects. This specialty bit is designed to rout a stepped slot: the large diameter end bores the entry hole for the screw head, and the smaller diameter slot allows room for the screw shank, locking the piece firmly in place. Ideal for hanging pictures, plaques, mirrors, or custom shelves, the bit features TiCo™ Hi-Density Carbide for maximum performance and is finished with the anti-friction Perma-SHIELD® Coating, guaranteeing smooth routing in hard or soft wood, plywood, or composites.

Key Features

  • Concealed Fastening: Creates the perfect key hole slot for hanging plaques or shelving with completely invisible screws or nail heads.
  • Precision Stepped Profile: Features a 25/64" overall diameter for the screw head entry and a 3/16" small diameter for the final locking slot.
  • Industrial Carbide: Made with TiCo™ Hi-Density Carbide for superior cutting performance and long life, even when routing dense hardwoods.
  • Universal Use: Suitable for use on CNC and automatic routers, as well as hand-held and table-mounted portable routers.
  • Anti-Friction Coating: Freud Perma-SHIELD® Coating protects the bit from heat, gumming, and corrosion for consistently clean cuts.
