B&D DW5458 27/32 X 8IN ROCK CARBIDE

Guaranteed to set up to 25% more anchors than standard masonry bits, DEWALT SDS Plus Masonry Drill Bits power through masonry, concrete, and more with a carbide tip that maximizes bit life. An elongated 4-flute helix helps to increase material removal, and 3 flats on the shank helps to prevent slippage.
