The DeWalt DW5447 is a professional-grade SDS Plus hammer bit designed for drilling through masonry, concrete, and stone. The 5/8-inch diameter carbide tip delivers fast, clean holes in hard materials while the SDS Plus quick-release shank ensures rapid, tool-free bit changes on any compatible hammer drill. This bit is engineered to handle the demands of anchor installation, core sampling, and demolition prep work where reliability and durability are essential.
Built for prolonged use on tough substrates, this hammer bit combines a heat-treated steel body with a carbide cutting edge that resists wear and extends service life. The elongated 4-flute helix design increases material removal and chip clearance, boosting productivity on the job site. The three flats on the shank prevent slippage during operation, ensuring consistent torque transfer and accurate drilling. Whether you’re a professional contractor tackling reinforced concrete or a dedicated DIYer working on a masonry project, this bit delivers the performance and precision you need.
