Dewalt DW5446B25 Sds Plus Masonry Drill Bit 25 Pack

Product Description

The DEWALT DW5446B25 is a Rock Carbide SDS Plus masonry drill bit sold in a 25-pack, engineered for high-volume anchor setting in concrete, block, and masonry applications. The bit measures 5/8 inches in diameter with a 6-inch usable length and 8-inch overall length. A serrated titanium carbide tip delivers extended drilling life under hard use, while the SDS Plus shank provides positive chuck engagement and efficient hammer energy transfer. This bit is designed for professional masonry installers, concrete contractors, and construction tradespeople who drill anchor holes at volume.

The DW5446B25 is suited for residential and commercial masonry work where anchor setting speed and bit longevity are priorities. The improved flute geometry moves dust out of the bore quickly, reducing heat buildup and maintaining consistent hole quality over repeated cycles. It is a practical choice for setting wedge anchors, sleeve anchors, and similar fasteners in poured concrete and CMU block.

Key Features

• Rock Carbide tip construction for extended bit life in abrasive masonry materials
• Serrated titanium carbide tip geometry rated for up to 25 percent more anchors per bit versus standard designs
• Pilot point tip starts on contact for accurate hole placement without walking
• Improved flute design evacuates dust rapidly for faster, cooler drilling
• SDS Plus shank fits standard SDS Plus rotary hammers for positive drive engagement
• 25-pack quantity reduces downtime on high-volume anchor-setting jobs

Compatibility

Designed for use with standard SDS Plus rotary hammers. The SDS Plus shank interface is an industry-standard format accepted by SDS Plus chucks from major rotary hammer manufacturers.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary hammer operation and masonry anchor installation procedures. Confirm the rotary hammer is set to hammer-drill mode and the chuck is fully locked onto the SDS Plus shank before drilling. Wear appropriate PPE including eye protection and a dust mask rated for silica-containing dust. Follow applicable OSHA silica exposure guidelines and local codes when drilling concrete or masonry.
