Product Description
The Milwaukee 48-20-3952 SDS-Max MX4 Rotary Hammer Drill Bit is engineered for heavy-duty drilling in concrete, reinforced concrete, brick, and masonry using SDS-Max rotary hammer drills. It features a solid carbide MX4 4-cutter head, which provides greater durability and allows the bit to drill efficiently even when encountering embedded rebar.
The 4-cutter design prevents the bit from locking up when hitting rebar, reducing tool damage and downtime during demanding construction work. A precision centering tip helps ensure accurate hole starts, while breaker points pulverize material for faster drilling speeds.
Its optimized variable flute design efficiently removes dust and debris from the hole, helping maintain drilling speed and reducing heat buildup. Reinforced flutes increase durability and extend the bit’s life in tough job-site conditions.
