This is our collection of coversion tools for automatic knife making. Some of the auto conversion tools include carbide spade drills, spring pocket cutter bits, and replacement pilots. The solid carbide spade drills are of the highest quality and are used for drilling spring holes in pre-hardened blades. If you're converting a knife to an auto, these are what you need to make the acceptor hole needed for the coil spring tip. For metal hole making, our coil spring pocket cutters provide fast, accurate, burr-free holes in steel materials. These are annular cutting tools that cut around the edge of the hole and eject the center as a slug. Because they're hollow, there is no dead zone, as with twist drills. Unlike hole saws that rip and tear through the material, they quickly give you a quality, virtually burr-free hole. Our coil spring pocket cutters are available in 3 sizes. These are the best spring pocket cutters available to help you convert your folding knife into an automatic.
