Milwaukee SDS Plus 4-Cutter MX4 1/4″ x 4″ x 6″ Drill Bit 100 Pack 48-20-7994

REBAR-READY PRECISION FOR HIGH-VOLUME ANCHORING

The Milwaukee MX4 4-Cutter SDS Plus drill bits are engineered for the professional who demands maximum uptime when drilling into hard aggregate and rebar-reinforced concrete. Featuring a solid head carbide construction, these bits deliver up to 5X longer life compared to standard masonry bits. The 4-cutter geometry is a critical mechanical advantage, preventing the bit from locking up or binding when encountering rebar, which significantly reduces the risk of tool kickback and bit breakage. Designed with variable flute geometry, the MX4 efficiently clears dust to minimize heat buildup, allowing for up to 20% more holes per charge on M18 FUEL rotary hammers.

• / Solid Head Carbide delivers up to 5X longer life in concrete with rebar for maximum professional ROI.
• / 4-Cutter design prevents lock-up in rebar, ensuring smooth drilling and reduced downtime in structural applications.
• / Sharp centering tip provides exact spot drilling, preventing bit walk on concrete and metal decking.
• / Integrated wear mark indicator provides a visual cue for ANSI B212.15 compliance, ensuring anchors are set to spec.
• / Optimized variable flutes clear debris faster, reducing thermal stress and extending battery runtime.
