The DeWalt DW5446 is a premium SDS Plus carbide hammer bit engineered for drilling into masonry, concrete, stone, and similar hard materials with rotary hammers. Designed to power through tough substrates efficiently, this bit features a tungsten carbide tip that resists wear and maintains sharpness through extended use, reducing downtime and boosting productivity on job sites.
Whether you’re setting concrete anchors, breaking through masonry for installation work, or drilling precise holes in stone, this hammer bit delivers the cutting efficiency and durability professionals demand. The carbide construction minimizes breakage risk in high-impact applications, while the SDS Plus shank connection ensures quick, tool-free bit changes and optimal power transfer to your hammer drill.
Features and Benefits
- Carbide tip: Premium tungsten carbide delivers long-lasting sharpness and superior wear resistance for consistent drilling performance in hard materials.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically-treated lumber.Your risk from these exposures varies, depending on how often you do this type of work.To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
