High performance heavy concrete drilling with Dewalt
- Solid 4-cutter carbide head: You drill clean and concentric holes through reinforced concrete, ensuring optimal holding power for all your heavy anchors.
- Fast and efficient dust removal: The 4-flute helix channels debris away rapidly so you maintain maximum drilling speed without jamming.
- Reinforced core for durability: The hardened core maximizes impact transfer from your SDS-MAX hammer while reducing bit breakage under severe load.
With the Dewalt DT9412-QZ SDS-Max hammer drill bit, you drill quickly and cleanly through the toughest base materials. The solid 4-cutter carbide head powers effortlessly through reinforced concrete, natural stone, and masonry without jamming on rebar. This ensures perfectly concentric holes for secure structural anchoring and service pass-throughs. Featuring a 400 mm working length and 540 mm total length, it gives you the reach needed for deep penetrations. The 4-flute helix with an open head design channels dust and debris away instantly to maintain drilling speed, while the reinforced core maximizes impact transfer from your SDS-Max rotary hammer and prevents breakage.
