Outstanding lifespan in reinforced concrete! High-quality, tough tungsten carbide ensures strength and durability. Reinforced concrete is commonly used in infrastructure, commercial, and residential construction. Our PRO SDS max-4 hammer drill helps construction workers effectively drill into this material. The drills feature a robust 4-cutter design that prevents them from jamming or breaking when hitting rebar. The 4-cutter head made of high-quality tungsten carbide provides comfort for professionals who need to drill precise holes in reinforced concrete. The spiral with deep channels effectively removes dust and debris generated when drilling with large diameter SDS max drills. Therefore, our SDS drill offers excellent performance for an even longer time.
