Low friction polymer collar. No surface scratches or burn marks!
These tools combine carbide countersink, high-speed-steel drill bit and free-spinning, low friction depth-stop. The countersink leaves a clean hole edge and the adjustable depth-stop doesn’t mar the surface. The large openings around the collar allow the chips to clear effectively and eliminate clogging. Quick release 1/4" hex shank with slow spiral, HSS?M2 fully ground drill bit included.
