MASONRY DRILL BITS
The SpeedHammer Power SDS-plus masonry bits, according to the manufacturer, are durable enough to power through rebar-reinforced concrete, masonry, and other tough material. The tip reportedly features two times more carbide than traditional masonry bits and are designed to cut through rebar at high speed. Also, the bits are made of premium steel for core strength, and the flute is designed for fast, efficient dust removal. (800) GO-IRWIN, Irwin.com
