1 in. x 16 in. x 21-1/2 in. SDS-MAX High-Impact 4-Cutter Carbide Drill Rotary Hammer Masonry Bit | DEW-DW5819

DEWALT's 1 in. x 21-1/2 in. SDS-Max 4-Cutter Carbide-Tipped Bit for Rotary Hammer combines a durable carbide cutting head with a flute design intended to move drilling dust efficiently from the hole. Its extended working length is useful for applications requiring deeper penetration, including anchor installation, electrical and plumbing penetrations, and general concrete construction. A four-cutter configuration helps produce consistent hole geometry while distributing cutting forces across multiple edges. Built for SDS-Max rotary hammers, this masonry drill bit gives contractors, electricians, plumbers, remodelers, and experienced DIYers a practical option for large-scale concrete and masonry drilling where standard rotary hammer bits lack the necessary reach

• Four-cutter carbide tip provides multiple cutting edges for efficient concrete and masonry drilling
• Extended 16 in. flute length provides substantial usable drilling depth for deep-hole applications
• SDS-Max shank is designed for compatibility with SDS-Max rotary hammers
• Carbide-tipped construction is suited to concrete, reinforced concrete, and masonry applications
• Provides extended reach for demanding drilling tasks
