Milwaukee SDS Plus MX4 4-Cutter 1-1/4" x 16" x 18" Drill Bit 48-20-7266

INDUSTRIAL GRADE MASONRY DOMINANCE

For the jobsite supervisor managing high-volume drilling operations, the Milwaukee MX4™ 4-cutter series is the definitive solution to the high cost of bit failure and onsite downtime. Designed to outperform standard two-cutter bits in the most aggressive aggregate, this 1-1/4" solid-head carbide bit maintains its integrity even when striking heavy-duty rebar. The precision-engineered rebar guards act as a mechanical buffer, preventing the bit from seizing and protecting your crew from the violent kickback often associated with inferior masonry accessories. By optimizing the variable flute architecture, Milwaukee has ensured that dust extraction is near-instantaneous, keeping the head cool and extending the life of your rotary hammer fleet.

• / SOLID HEAD CARBIDE: Engineered to deliver up to 5X more life in rebar-heavy concrete compared to standard bits.
• / 4-CUTTER GEOMETRY: Minimizes vibration and prevents binding when encountering steel reinforcement for smoother drilling.
• / WEAR MARK INDICATOR: Provides a clear visual reference to ensure the bit still meets ANSI hole-diameter specifications for critical anchoring.
• / CENTERING TIP: Enables pinpoint accuracy during the initial plunge, eliminating bit walk on smooth or slick concrete surfaces.
• / VARIABLE FLUTE DESIGN: Dramatically reduces friction and heat buildup, resulting in 20% more holes per battery charge.
