The Best Keyhole Router Bits for Woodworking

three keyhole router bits side by sideKeyhole router bits are handy tools to have on hand for homeowners and professional woodworkers alike. The main use for keyhole router bits is for mounting pictures, plaques, shelves, and other home accessories. Many people like these tools because they’re relatively simple to use and don’t necessarily require extra hardware. They also don’t show the mounting screws once their shelf or picture frame is in place. Keyhole router bits are handy because the holes they create allow you to make sure your home decorations are tight against the wall instead of sticking out slightly. Take a look at these keyhole router bits we recommend for you.

What to Look for in a Keyhole Router Bit

Make sure you consider these things before buying a keyhole router bit:

  • Size and Diameter: Be sure that the keyhole router bit in question creates holes that will fit the screws you’re using for your project as well as your table router if you plan to use them in tandem.
  • Drill Compatibility: While it’s not necessary for usage, some people like to mount their keyhole router bits on drills. Not all are drill-compatible, however.
  • Versatility: Most keyhole router bits work on solid wood as well as plywood, particleboard, and other similar materials, but it never hurts to double-check.
  • Material: The harder and more durable steel or metal keyhole router bits the better, as harder metals tend to give you cleaner cuts.
