Milwaukee SDS Plus 4-Cutter MX4 7/8" x 8" x 10" Drill Bit 48-20-7228

REINFORCED CONCRETE DOMINANCE: THE MX4™ 4-CUTTER ADVANTAGE

When drilling into high-PSI concrete reinforced with rebar, mechanical failure is usually a matter of 'when,' not 'if.' The Milwaukee MX4™ 4-Cutter series redefines professional ROI by utilizing a solid head carbide design that delivers up to 5X longer life compared to standard bits. Engineered to withstand the extreme thermal stress of hard aggregate, these bits feature integrated rebar guards that prevent the 4-cutter head from locking up or snapping upon impact with steel. For the high-volume professional, the variable flute geometry is a critical efficiency upgrade, evacuating dust rapidly to reduce heat friction and providing up to 20% more holes per battery charge on cordless SDS Plus platforms.

• / Solid head carbide construction provides maximum durability and 5X life in rebar-embedded concrete.
• / Advanced 4-cutter geometry prevents binding and lock-up, ensuring smoother drilling through structural steel.
• / Variable flute design optimizes debris removal to deliver 20% more holes per charge on M18 FUEL™ systems.
• / Integrated wear mark indicator provides a visual gauge to ensure holes meet ANSI B212.15 anchor requirements.
