Mx4 Sds-plus 3/8 In X 12 In 4-cutter Rotary Hammer Drill Bit

Presenting Milwaukee MX4 SDS-Plus 3/8 in x 12 in Four-Cutter Rotary Hammer Drill Bit, a high-performance bit engineered for reinforced concrete and masonry. The solid-carbide head delivers exceptional wear resistance, while built-in rebar guards help withstand tough aggregates and embedded steel. Its four-cutter design minimizes lock-ups, reducing downtime on demanding jobs. A sharp centering tip ensures accurate starting holes in concrete and metal decking. The bit's variable flute geometry speeds dust clearance, lowers heat, and yields more holes per battery charge. A wear-mark indicator shows when the bit has reached end-of-life and still meets ANSI performance standards. The MX4 family is ideal for concrete with rebar and masonry tasks.

Boosts productivity and reliability: With reinforced durability and proactive dust management, this bit helps you drill more efficiently through tough concrete with rebar, reducing tool changes and improving job-site efficiency.

• Carbide head: Durable solid-carbide tip provides long-wearing performance in reinforced concrete and masonry, lowering replacement frequency.
• Rebar guards: Protective shields guard the tip from rebar and harsh aggregates, extending bit life on demanding projects.
• Four-cutter design: Optimized cutters prevent jamming and deliver smoother drilling through tough concrete and rebar-rich substrates.
• Centering tip: Sharp starting point ensures precise hole placement in concrete and metal decking for accurate installations.
• Dust removal & wear indicator: Variable flutes evacuate debris quickly, keeping temperatures down and boosting holes per charge while signaling end-of-life and ANSI compliance.

Why choose this Milwaukee MX4 bit for your SDS-Plus drill: Built to excel in professional construction settings, this bit delivers reliable performance when drilling through reinforced concrete and masonry. The combination of carbide durability, rebar protection, and a smart four-cutter design translates into longer service life and fewer interruptions. Whether you're installing anchors or running conduit, this bit helps you complete tough jobs faster with cleaner holes and consistent results.
