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.
Warning: When drilling aluminum/non-ferrous materials, for optimal results and extended tool life use lubricant or air cooling. Make sure the material is fixed and drill is stable during drilling. Disconnect from any vacuum system. Using Low RPM is recommended.
