Description

The DT9547-QZ is a DEWALT EXTREME 10mm x 1000mm (940mm working length) SDS-Plus 2-cutter drill bit for drilling 10mm diameter holes in concrete, masonry, brick, and stone using SDS-Plus rotary hammer drills. The EXTREME2 tip design features a solid 2-cutter carbide head flanked by two individual cutting tips, delivering fast and efficient drilling speed with a four-flute spiral that enables quick debris removal to maintain consistent drilling speed throughout the full working depth.
Superior carbide grade provides long bit life — up to 50% more holes per battery charge on cordless rotary hammers versus standard bits. The hardened steel body with strong tapered core web design greatly reduces the risk of breakage, particularly when striking rebar in reinforced concrete. The optimised mounting shank provides perfect grip and optimum power transmission. The exceptional 1000mm length enables through-wall drilling in multiple thick masonry layers or very deep structural penetrations in a single operation without repositioning.
Compatible with all SDS-Plus rotary hammer drills. Suitable for plug, anchor, clearance holes, and fixing applications in masonry, stone, concrete, and brick/blockwork.
