Milwaukee MX4 4-Cutter SDS MAX Rotary Hammer Drill Bit 1-1/4" x 18" x 23" 48-20-8972

REINFORCED CONCRETE DOMINANCE WITH SOLID HEAD CARBIDE PRECISION

When you're punching 1-1/4" holes through high-PSI concrete, the biggest productivity killer isn't the material—it's the rebar. The Milwaukee MX4™ SDS MAX bits are engineered to solve the binding problem that plagues standard 2-cutter bits. By utilizing a solid head carbide and a 4-cutter geometry, these bits maintain a consistent drilling speed even when encountering heavy reinforcement. The integrated rebar guards act as a shield, preventing the bit from locking up or shattering upon impact with steel. For the professional contractor, this means less downtime, fewer broken bits, and a significantly lower cost-per-hole over the life of the accessory.

• / Solid Head Carbide construction delivers up to 5x longer life in heavy-duty concrete and rebar applications.
• / Advanced 4-Cutter geometry prevents bit lock-up and binding when striking rebar, ensuring operator safety and tool longevity.
• / Precision-engineered centering tip allows for exact spot drilling, preventing bit walk on smooth or uneven surfaces.
• / Optimized flute design accelerates dust removal to reduce friction and heat, maximizing holes per battery charge on cordless SDS MAX hammers.
• / Integrated Wear Mark Indicators provide a clear visual reference for ANSI B212.15 compliance, ensuring anchors set correctly every time.
