Pro-Tech | Router Keyhole Bit 3/8″ X 1/8″ 1/4″ Shank

Keyhole or hang slot cutter
Keyhole cutter 9.58mm wide
This bit is so different from the usual “edge treatment” bits that it deserves highlighting.
It is a highly specialised bit that is used for one purpose only, to cut keyhole slots in picture frames or any object you would like to hang flat against a wall. If you have ever owned one of these bits, you know that it saves a lot of money and a lot of frustration.
Keyhole slots can be put in most picture frames. For a heavy frame, use two slots and two hanging screws. The process is quick and reliable, and saves endless wire and hooks, which you never have anyway when you need them.
These bits are single fluted for easier plunging. When you want to hang a shelf, picture frame, clock, or candle sconce on a wall but don’t want the mounting screws to show, use an inexpensive keyhole router bit to cut screw slots instead. Then, when you hang the piece, it will appear to “float” on the wall. And, with keyhole slots you don’t need special hardware. Once you’ve got the tools set up, you can cut multiple slots quickly and easily.
This router bit has a
6.35 mm shank
(shaft) that will fit most small routers. Please ensure that you select a router bit with a shank (shaft) size that will fit into your router collet.
