Product Description
The Milwaukee 48-20-3946 SDS-Max MX4 Rotary Hammer Drill Bit is engineered for high-performance drilling in concrete, reinforced concrete, brick, and masonry. It features Milwaukee’s MX4 solid-carbide 4-cutter head, which provides exceptional durability and allows the bit to drill efficiently even when encountering embedded rebar.
The 4-cutter head design helps prevent the bit from binding when it hits rebar, reducing tool damage and downtime. The precision centering tip enables accurate hole starts, while breaker points pulverize concrete material to improve drilling speed.
This bit also incorporates optimized variable flute geometry, which helps remove dust and debris quickly from the hole, improving drilling efficiency and extending tool life. Reinforced flutes increase durability in heavy-duty job-site conditions.
