Lasts up to 1.5x longer than a Bosch SDS max-2 Drill Bit Reinforced concrete is a common material in infrastructure, commercial, and domestic construction. We made PRO SDS max-4 Hammer Drill Bits to help construction workers drill in it. The drill bits have a hardy 4-cutter design that prevents them from jamming or breaking when you hit rebar. Made from high-quality tungsten carbide, the PRO SDS max-4's 4-cutter head offers convenience to professionals who need to drill accurate holes in reinforced concrete. Its fluting with a deep-channel design effectively removes the dust and chips generated by large-diameter SDS-max drilling, which means our SDS drill bit offers great performance for longer. Fits all SDS max rotary hammer drills Tested in Bosch labs according to Bosch standard procedures. Features and Benefits: • Lasts up to 1.5x longer than a Bosch SDS max-2 Drill Bit • Fits all SDS max rotary hammer drills • For drilling holes in concrete and reinforced concrete, eg during residential and commercial building construction or civil engineering projects • Highly efficient for construction workers and civil engineers: Long Life Specifications: Diameter (D) mm: 25.00 Working length mm: 400 Total length mm: 520
