Fast drilling in reinforced concrete
- Durable Dewalt 4-cutter head: The solid carbide 4-cutter tip geometry resists rebar strikes and creates precise, concentric holes.
- Rapid debris removal design: The 4-flute helix clears dust quickly from the hole so you maintain consistent drilling speed.
- Efficient impact energy transfer: A reinforced core with SDS-Max shank ensures you transfer full hammer energy directly to the tip.
With the Dewalt DT9420-QZ SDS-Max hammer drill bit, you drill deep, precise holes through reinforced concrete, masonry, and natural stone. The robust 4-cutter carbide head delivers concentric holes and prevents jamming when striking rebar. Offering a 400 mm working length and a 540 mm overall length, this bit is ideal for drilling deep wall penetrations for conduit and pipework, as well as structural anchor fixings. The reinforced core and SDS-Max shank transfer full hammer impact energy without slipping, while the 4-flute helix clears dust and debris quickly. This ensures you maintain drilling speed and control on demanding jobsite applications.
