Product Description

The Milwaukee 48-20-3918 SDS-Max MX4 Rotary Hammer Drill Bit is a professional-grade drilling accessory designed for heavy-duty concrete and masonry drilling using SDS-Max rotary hammer drills. It features a solid carbide 4-cutter head, which increases durability and drilling speed when working in reinforced concrete and hard aggregate.

The 4-cutter design helps prevent the bit from locking up when it hits rebar, allowing smoother drilling and reducing the chance of tip breakage. A precision centering tip ensures accurate hole starting, while the variable flute design improves dust removal to maintain faster drilling performance.

Milwaukee also includes reinforced flutes and rear guards to protect the bit during demanding applications, increasing overall tool life in tough job-site conditions.
