Milwaukee SDS Max 4CT MX4™ 1-3/4" X 18" X 23"

MAXIMUM AGGREGATE ENDURANCE

When your crew is staring down high-PSI concrete laced with heavy rebar, the efficiency of your consumables determines the profit margin of the pour. The Milwaukee 48-20-3992 MX4 SDS Max bit is engineered to eliminate the catastrophic lock-up failure points common in standard 2-cutter designs. By utilizing a precision-engineered solid head carbide geometry, this bit maintains structural integrity through repeated rebar strikes, ensuring your heavy-duty rotary hammers stay out of the repair shop and on the deck for maximum fleet ROI.

• / Solid Head Carbide: Delivers up to 5x longer life in reinforced concrete, drastically lowering your cost-per-hole in demanding environments.
• / Integrated Rebar Guards: Specifically designed to deflect high-impact strikes in hard aggregate, preventing bit shattering and mid-day downtime.
• / Sharp Centering Tip: Provides surgical accuracy for spot drilling into concrete and metal decking, preventing bit walk and ensuring proper anchor placement.
• / Optimized Variable Flutes: Evacuates debris with high efficiency to reduce thermal buildup and increase total holes-per-charge by 15%.
• / Wear Mark Indicators: Visual indicators ensure your holes always meet ANSI B212.15 compliance by identifying bit life status before the anchor fails.
