Product details

Designed for deburring and countersinking in soft metal. Do you need a reliable countersink for precise deburring and countersinking in soft non-ferrous metal? Then the PRO Soft Metal HSS Countersink is the right choice. We have developed it for the effective deburring and countersinking of pre-drilled holes. The PRO Soft Metal HSS Countersink is an excellent option for builders and installers who need to deburr and countersink pre-drilled holes in soft metals like aluminum and copper. The countersink is made from high-speed steel (HSS) for strength and heat resistance. It features three 90° cutting edges, allowing you to create clean, burr-free countersinks exactly where you need them. The cylindrical shank is suitable for chuck drills.
