The classic MiS countersink - drill your pilot hole and countersink in one motion, all using an impact driver or Quick Change Chuck. Set the depth stop with the included allen key, so that you can drive a screw flush with the surface or counterbore to leave room for a plug. The 82° countersink is designed to match the head of most standard screws. See our Screw Size chart to match screw to countersink.
If you’re worried about marring the project surface, pick up a Premium Rotating Depth Stop. Made with precision chrome bearings, the large stop surface minimizes or eliminates friction, providing a perfect countersink without a telltale halo around the screw.
Made in the USA.
