Product Description
The Milwaukee 48-20-3930 SDS-Max MX4 Rotary Hammer Drill Bit is a professional-grade drilling accessory designed for rotary hammer drills used in demanding concrete and masonry applications. It features a solid carbide 4-cutter head (MX4 design) that improves durability and delivers reliable performance when drilling through reinforced concrete and hard aggregate.
The 4-cutter head geometry helps prevent the bit from locking up when it encounters rebar, reducing downtime and protecting the tool from damage. A precision centering tip allows accurate hole placement, while breaker points help pulverize material for faster drilling speeds.
The bit also includes variable flute geometry, which efficiently removes dust from the hole to maintain drilling efficiency and reduce heat buildup. Reinforced flutes and rear guards add durability when working in tough construction environments.
