I have a box full of wood screws/counter drill bits. I've tried all sorts and this is the only one that works consistently. All others overheat easily or drill poorly, or the drill or countersink rotates. I've tried various methods (including Loctite) to prevent this from happening, but none of the solutions worked for very long. The only wood screw/countersink drill that works smoothly, quickly and without rotation is the Dewalt drill. Highly recommended.
