Masonry Drill Bit Set, Percussion, 4-Piece (DW5204)

The DeWalt DW5204 4-piece premium percussion masonry drill bit set is used primarily for drilling small diameter holes in masonry, concrete, rock, and artificial stone. DeWalt built each bit with a rock carbide tip that maximizes carbon surface contact for an extended bit life. And with the 4-flute design, the bits remove debris as you work for fast, efficient drilling. For added safety, each bit is designed with three flats on the shank that prevent the bit from slipping back into the chuck, and an innovative tip that reduces walking and increases accuracy. Used primarily to drill holes for mechanical anchors, these bits fit into standard 3/8-inch and 1/2-inch chucks. This 4-piece set includes the following bits: 3/16-by-3-inch, 1/4-by-4-inch, 5/16-by-6-inch, and 3/8-by-6-inch.
