Milwaukee SDS Plus 4-Cutter MX4™ 1/2" x 16" x 18" Drill Bit 48-20-7377

MAXIMUM REBAR ENDURANCE FOR HIGH-VOLUME ANCHORING

When your crew is drilling deep into reinforced concrete, the mechanical failure of a standard bit hitting rebar is a major drain on productivity. The Milwaukee MX4™ 4-Cutter SDS Plus bit is engineered to solve this through a solid head carbide construction that maintains structural integrity even under high-heat friction. By utilizing a symmetric 4-cutter geometry, this bit eliminates the common lock-up and binding issues found in 2-cutter designs, ensuring smoother penetration through hard aggregate. The variable flute design is a critical mechanical advantage for cordless users, as it optimizes dust evacuation to reduce drag, effectively delivering up to 20% more holes per charge on your M18 FUEL platform.

• / Solid Head Carbide construction provides up to 5X longer life in concrete with rebar compared to standard bits.
• / 4-Cutter geometry prevents binding and lock-up when encountering rebar, reducing downtime and tool kickback.
• / Sharp centering tip allows for exact spot drilling in concrete and metal decking without bit walking.
• / Wear mark indicator provides a visual reference for ANSI B212.15 compliance, ensuring anchors set correctly every time.
