With the Dewalt DT9556-QZ hammer drill bit, you drive fast and accurately through concrete, stone, and masonry. Equipped with a 2-cutter carbide tip, it smoothly penetrates tough materials, while the 300 mm working length and 350 mm total length give you the reach needed for deep anchor holes and conduit pass-throughs. The SDS-plus shank secures firmly into your rotary hammer for direct impact transfer without slipping. Built with a hardened steel body, this durable bit resists breakage during demanding drilling tasks.
