Description

This keyhole t-slot cutter bit (a.k.a. key slot cutter, key slot bit) is designed for deeper slot depths when your wall-hanging wood projects are extra heavy. 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. They are especially important when making heavier projects that hang on walls, such as wood shelving, or deep shadow boxes. The keyhole t-slots ensure your project is flush to the wall and secure.

Keyhole slots are far stronger than using wire or metal serrated hangers. This 3/8 inch keyhole bit is good for manual routers also.

If you are planning on designing plans and making a DIY cribbage board game, you want the holes to be perfectly positioned. Whether you are making it by hand with a drilling jig or on a CNC router, choosing any drill can lead to problems in your project. They are stated below.
