Milwaukee SDS Plus 4CT MX4™ 3/8" X 10" X 12"

REINFORCED CONCRETE DOMINANCE WITH MX4 CARBIDE TECHNOLOGY

The Milwaukee MX4 series represents a significant leap in masonry drilling efficiency, specifically engineered to solve the primary failure point of standard bits: rebar strikes. By utilizing a solid head carbide design rather than a simple inlay, this bit maintains structural integrity under extreme heat and mechanical stress. The 4-cutter geometry is critical for professional productivity, as it prevents the bit from binding or locking up when encountering steel reinforcement, a common issue that leads to snapped bits and user fatigue. Furthermore, the variable flute geometry is optimized for high-speed dust evacuation, which directly translates to a 20% increase in holes per charge when paired with M18 FUEL rotary hammers, maximizing the ROI of your cordless platform.

• / Solid Head Carbide Construction: Delivers up to 5X longer life in heavy-duty concrete and rebar applications compared to standard bits.
• / Advanced Rebar Guards: Engineered to withstand hard aggregate impacts and prevent catastrophic failure during steel encounters.
• / Precision Centering Tip: Ensures exact spot drilling and prevents bit walking on smooth surfaces or metal decking.
• / ANSI Wear Mark Indicator: Provides a clear visual reference for bit replacement to ensure every hole meets strict anchor installation tolerances.
