Work holes into hard materials with this drill bit from Dormer. It works together with a drilling machine and rotates rapidly to apply axial force on surfaces, creating channels for fastener installation. The part is built for tough settings, thanks to a high-speed steel body that can withstand impact and wear. It supports right-hand rotation, which reduces the risk of chip accumulation and heat build-up in the cutting area.
