Amazon.com The DW5821 SDS Max Rotary Hammer Bit handles the toughest concrete, stone, and other masonry materials with ease. Its Rock Carbide tip extends bit life much longer than other bits, and its tough steel construction makes this hammer bit durable and long-lasting. The DW5821's open head design helps channel dust and debris into the flutes for more efficient drilling, and the helix four-flute construction removes this debris from the drilling surface quickly for easier drilling.
