This 5-inch SDS-Max drill bit delivers superior performance for heavy-duty concrete drilling applications. Featuring a 4-cutter carbide tip design that provides up to 20% faster drilling speed and exceptional durability in reinforced concrete. The optimized flute geometry efficiently removes dust and debris, reducing binding and overheating while extending bit life. Engineered with Milwaukee's proprietary heat-treatment process, this bit maintains sharpness longer than standard bits, allowing you to complete more holes per charge and reducing downtime on demanding jobsites.
