Product Description

The Milwaukee Electric Tool Corp 48-20-9031 is a carbide hammer drill bit engineered for fast, reliable drilling in concrete and masonry. Built with a reinforced carbide tip, it withstands the repeated impact loads of rotary hammer and impact driver use. The 1/2 inch hex shank provides positive engagement in impact drivers and compatible chuck systems. Overall length is 12 inches with a usable drilling depth of 10 inches, giving trades-people adequate clearance for anchor and fastener applications in structural and finish work.
