The new SpeedHammer Power SDS-plus Masonry Bit from Irwin Tools was designed for users drilling through rebar-reinforced concrete and masonry. A high-performance tip is manufactured with two times more carbide than traditional masonry bits and optimized for cutting through rebar at high speeds. The flute is designed for fast and efficient dust removal with a specially engineered groove design that minimized friction. The bits are available in 6-, 8-, and 12-in. lengths, with diameters ranging from 3/16 to 3/4 in.
