These are used for cutting the coil spring cavity needed for a folding knife.
For metal hole making, our spring coil cutters provide fast, accurate, burr-free holes in steel materials up to 3/16″ thick. 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’s 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 are available separately in 3 sizes for 1/4″ and larger drill chucks. The pocket cutter bit shown is not included with the guide. It is shown for illustrative purposes only. The bits are available . Spring loaded replaceable arbor pilot “pops” the slug from the cutter. These pocket cutter bits are very nice.
