Description

The DT9682-QZ is a DEWALT ELITE SERIES 18mm x 250mm (200mm working length) SDS-Plus 4-cutter drill bit for drilling large-diameter holes in concrete, reinforced concrete, and masonry using SDS-Plus rotary hammer drills. The 4-cutter open-head carbide design with four main cutting faces maximises hole concentricity for better anchor and fixing retention, and channels dust into the four-flute spiral for fast, efficient debris removal — delivering consistently faster drilling than standard 2-cutter bits at these larger diameters.
The tapered core provides strength and resistance to flute breakage, particularly important when striking rebar in reinforced concrete at these larger diameters. The four-flute helix maximises debris removal for consistent drilling speed throughout the full working length. IRON BLAST TECHNOLOGY strengthens the bit body against fatigue for extreme durability in demanding construction applications.
Compatible with all SDS-Plus rotary hammer drills capable of handling this diameter range. Suitable for heavy mechanical anchor installation, large conduit clearance holes, and structural fixing applications in concrete, masonry, brick, and blockwork.
