This keyhole router bit, keyhole cutter, for CNC routers (a.k.a. t-slot cutter, keyhole slot cutter, key slot bit) is a woodworking bit designed for T slot on your wall-hanging wood projects. Keyhole t-slot bits for CNC routers are used to cut slots in wood projects when you want them to be flush to the wall, such as plaques, or awards.

The keyhole router bit is especially important when making heavier woodworking projects that hang on walls, such as wood shelving, or deep shadow boxes.

The flutes on this bit are designed to cut down AND sideways cleanly to make your keyhole slots virtually sanding-free.

Keyhole router bit slots are far stronger than using wire or metal serrated hangers and they allow your woodworking CNC project to rest flush against the wall. This 3/8 inch keyhole bit is good for manual routers also.

To see how to set up your keyhole in your design software, watch this YouTube video.

1/4 shank bits

They worked great….just remember that they have a limited depth of cut,,,,it never crossed my mind until I tried to cut thru a 1.2 “ project. It didn’t go well

3/8 Keyhole bit

Fast and accurate delivery as always, haven’t used this latest bit yet. Every bit in my inventory is IDC, flawless performance and top of the line quality. Will need to rewatch the video setup Garrett did awhile back. Thanks for the quick service.

Dru Beattie

Have been very pleased with this product. The only thing I can say that I’d like to see different, is a little clear instructions for set up gear towards newbies, especially. Will continue to order from them again.
