Milwaukee 1-1/4" x 12" Diamond Premium Wet Core Bit Extension 48-17-4012

DEEP-REACH STRUCTURAL CORING FOR HEAVY CIVIL APPLICATIONS

When you're pulling cores through reinforced bridge decks or thick structural footings, standard bit lengths often hit their limit before the job is done. This 12-inch extension is engineered to maintain structural rigidity under the high-torque demands of MX FUEL and large-frame core rigs. By extending your reach without sacrificing concentricity, you ensure clean, straight bores through the heaviest concrete and rebar configurations. Designed specifically for wet-drilling environments, this extension allows for consistent cooling and slurry removal during deep-hole operations where precision is non-negotiable.

• / 12-Inch Extended Depth: Penetrate deeper into thick slabs and structural footings where standard core bits cannot reach.
• / High-Torque Threaded Connection: Built to handle the immense rotational force of industrial core motors without stripping or binding under load.
• / Wet-Application Optimized: Specifically engineered for continuous wet-drilling to ensure maximum bit life and efficient debris flushing.
• / Professional Maintenance Design: Requires anti-seize lubricant application to prevent heat-fusing, ensuring easy breakdown after heavy-duty use.
