Milwaukee SDS Plus 4-Cutter MX4 5/32″ X 4″ X 6″ Drill Bit 48-20-7308

MAXIMUM DURABILITY FOR HIGH-STAKES CONCRETE PENETRATION

In high-PSI concrete applications, hitting rebar is the primary cause of bit failure and jobsite downtime. The Milwaukee MX4 series is engineered to solve this mechanical bottleneck. By utilizing a solid head carbide and a 4-cutter geometry, this bit doesn’t just survive rebar strikesit maintains its structural integrity where standard 2-cutter bits would bind or snap. The variable flute design is a critical advantage for professional crews, as it clears spoils faster to reduce friction and heat, directly translating to more holes per charge on your cordless rotary hammer. This bit is designed for the professional who demands long-term ROI and precision in hard aggregate environments.

• / Solid head carbide construction provides up to 5X longer life when encountering rebar in reinforced concrete.
• / Integrated rebar guards protect the bit from catastrophic failure and prevent lock-up during hard aggregate impacts.
• / Sharp centering tip ensures precision placement on smooth surfaces and metal decking without bit walk.
• / Variable flute geometry optimizes dust extraction, keeping the bit cool and extending battery runtime by up to 20%.
• / Wear mark indicator provides a visual gauge for ANSI B212.15 compliance, ensuring anchor seating integrity.
