Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 5/8" x 7" x 13" 48-20-3916

PRECISION ANCHORING THROUGH REBAR-REINFORCED CONCRETE

When drilling deep into structural concrete, the mechanical failure of a bit isn't just an inconvenience—it's a direct hit to your project's ROI. The Milwaukee MX4 SDS Max bit is engineered with a solid carbide head that maintains structural integrity even when encountering heavy rebar. The 4-cutter geometry is specifically designed to eliminate the lock-up common with standard 2-cutter bits, ensuring smooth power transfer from the rotary hammer to the substrate. Furthermore, the optimized variable flute design works in tandem with high-output batteries, clearing dust faster to reduce thermal load and maximize the number of holes drilled per charge.

• / Solid head carbide construction provides up to 5x more life in concrete with rebar compared to standard percussion bits.
• / Integrated rebar guards protect the carbide head from catastrophic failure during hard aggregate strikes and rebar encounters.
• / Sharp centering tip ensures exact hole placement, which is critical for meeting tight tolerances in professional anchor patterns.
• / Wear mark indicators provide a permanent visual reference to ensure the bit still meets ANSI B212.15 requirements for secure anchor fitment.
• / Variable flute geometry accelerates dust extraction, reducing heat buildup and extending cordless battery runtime by up to 15%.
