Milwaukee 3/4" x 30" x 36" MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3936

MAXIMIZING DRILLING EFFICIENCY IN REINFORCED CONCRETE

When your job requires deep-hole penetration through high-strength aggregate and rebar, the Milwaukee MX4 4-Cutter SDS Max bit is the mechanical solution for high-volume productivity. Engineered with a solid head carbide, this bit is designed to withstand the extreme thermal stress of continuous drilling, delivering up to 5x longer life compared to standard tipped bits. The 4-cutter geometry is specifically designed to eliminate the common failure point of bit lock-up when encountering rebar, ensuring a smoother drilling experience and protecting the operator from high-torque kickback. For professionals managing anchor installations, the integrated wear mark indicators provide a clear visual reference to ensure every hole remains within the strict ANSI B212.15 tolerances required for structural compliance.

• / Solid Head Carbide construction provides superior durability and maintains cutting speed in the toughest concrete with rebar.
• / Integrated Rebar Guards protect the carbide head from impact damage, significantly extending the service life of the bit.
• / Optimized Flute Design accelerates dust removal to reduce heat buildup, delivering up to 15% more holes per battery charge on cordless SDS Max hammers.
• / Sharp Centering Tip ensures exact spot drilling, preventing bit walk on smooth or uneven concrete surfaces.
• / Wear Mark Indicators allow for rapid inspection to confirm the bit still meets ANSI requirements for anchor setting.
