Milwaukee 3/4" x 16" x 21" MX4 4-Cutter SDS-MAX Rotary Hammer Drill Bit 48-20-3965

REINFORCED CONCRETE DOMINANCE

Engineered for the most grueling demolition and structural anchoring applications, the Milwaukee MX4™ 4-Cutter SDS-MAX bit represents a massive leap in accessory longevity for fleet managers and site foremen. Utilizing German-made solid head carbide, this bit eliminates the common failure point of traditional brazed-head designs when encountering heavy rebar. By integrating a specialized rebar guard, the 48-20-3965 manages thermal energy and mechanical stress more effectively than standard 2-cutter alternatives, ensuring your cordless SDS-MAX hammers maintain peak holes-per-charge metrics in hard aggregate and metal decking environments.

• / Solid Head Carbide construction provides up to 5x more life in high-stress rebar hits compared to standard bits.
• / Integrated Rebar Guards deflect impact and prevent the bit from seizing, significantly reducing downtime and user fatigue.
• / Precision Centering Tip ensures exact hole placement and prevents walking on smooth surfaces or metal decking.
• / High-Efficiency Flute Geometry accelerates dust extraction to reduce heat and deliver up to 15% more holes per battery charge.
• / Built-in Wear Mark Indicators provide a clear visual cue for ANSI B212.15 compliance, ensuring every anchor set meets code.
