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 a6.35 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.
PRO-TECH router bits are manufactured in Taiwan.

A simple template for cutting perfect keyholes |

| The first step would be is to use a guide bush that has a centre hole that is slightly larger than 10 mm as in the case with Pro-Tech router bit Model: KP501011. Attach the guide bush into the base of your router. |

The second step is to make a template. A scrap piece of plywood or similar material is perfect for the job.

Step 3 shows how the guide bush and the template will fit onto the workpiece. The router is not shown for clarity. |

Step 4 is not a difficult as it may seem. Just think carefully before start cutting the slot. The depth setup of the router bit through the guide bush is important. The slot part of the keyhole cutter should protrude enough to allow for the thickness of the template. (Try first on a scrap piece of wood). Remember the workpiece should hang, thus the large hole of the keyhole should be at the bottom. Once you are satisfied with the final depth of cut of the router and the depth gauge on the router is set, mount the router with guide bush into the template starting at the bottom of the desire keyhole slot you want to cut.
