Dewalt DW5403B25 Sds Plus Masonry Drill Bit 3/16x4.5x6.5 in

Product Description

The DEWALT DW5403B25 is a Rock Carbide SDS Plus masonry drill bit designed for rotary hammer drilling in concrete, block, brick, and similar masonry substrates. It measures 3/16 inches in diameter with a 4-1/2 inch usable length and an overall length of 6-1/2 inches. The serrated titanium carbide tip is engineered for extended drilling life under heavy use. An improved flute geometry evacuates dust from the hole quickly, reducing heat buildup and maintaining drill speed. This bit is compatible with SDS Plus rotary hammers and is typically installed by licensed contractors, masonry tradespeople, and experienced HVAC or plumbing technicians drilling anchor holes for equipment mounting.

The DW5403B25 is suited for setting anchors in poured concrete, concrete block, and brick in both residential and light commercial applications. It is commonly used when mounting HVAC equipment brackets, pipe hangers, electrical panels, or other mechanical trade hardware to masonry walls or floors. The bit is sold in a pack configuration with a minimum order quantity of one pack. It is rated to set up to 25 percent more anchors compared to standard masonry bits, making it a productive choice for high-volume anchor-setting work.
