Dewalt DW5503B25 Sds-plus Rotary Hammer Drill Bit 3/16 in

Product Description

The DEWALT DW5503B25 is a carbide-tipped SDS-Plus rotary hammer drill bit designed for drilling into concrete and masonry. At 3/16 inch in diameter, it features a 4-inch flute length and a 6.5-inch overall length. The SDS-Plus shank provides positive engagement in compatible rotary hammers, delivering efficient power transfer for high-volume drilling tasks. The carbide tip is paired with a high-speed steel body, giving the bit durability against the repeated impact loads generated by rotary hammer operation. This bit is sold in a 25-piece pack, making it well suited for contractors and tradespeople who need job-site quantities on hand.

This bit is used in residential and commercial construction for anchor hole drilling, fixture mounting, and penetration work in concrete, block, and masonry substrates. The 3/16-inch diameter is a common size for light-duty anchor applications and conduit sleeve installations. Rotary hammer drill bits of this type are typically deployed by electricians, plumbers, HVAC technicians, and general contractors whenever fastening to a concrete or masonry structure is required.

Eye protection and dust control measures are strongly recommended when drilling concrete or masonry. Follow local building codes and anchor-manufacturer guidelines for hole diameter, depth, and cleaning requirements before setting fasteners.
