Product Description
The Milwaukee 48-20-3932 SDS-Max MX4 Rotary Hammer Drill Bit is a professional-grade drilling accessory engineered for heavy-duty drilling in concrete, reinforced concrete, brick, and masonry. It uses Milwaukee’s MX4 solid-carbide 4-cutter head, designed to provide up to 5× longer life in concrete with rebar while maintaining high drilling speed.
The 4-cutter design prevents the bit from locking up when it encounters rebar, helping reduce downtime and improving durability during demanding job-site applications. A precision centering tip ensures accurate hole placement and easier hole starts in hard materials.
The bit also incorporates variable flute geometry, which removes dust efficiently from the hole, helping reduce heat buildup and improving drilling efficiency. Reinforced flutes increase durability when drilling in tough concrete applications.
