Milwaukee 12" Wet Core Bit Extension 48-17-4030
EXTENDED DEPTH PRECISION FOR CRITICAL STRUCTURAL PENETRATIONS
When structural specifications demand deep-hole coring through reinforced footings or thick bridge decks, the Milwaukee 48-17-4030 provides the critical 12-inch reach necessary to clear the slab without resetting your rig. Engineered for the high-torque environments of heavy civil jobsites, this extension maintains concentricity and power transfer during continuous wet drilling operations. It is designed to withstand the rigorous rotational stresses of MX FUEL and high-output corded core rigs, ensuring your diamond bits track straight even at extended depths.
- / 12-Inch Extended Reach: Adds critical depth to your drilling tube for thick-wall penetrations and deep structural sampling.
- / Industry-Standard Threading: Features a 1-1/4"-7 thread pattern for seamless compatibility with Milwaukee Premium wet core bits and professional-grade rigs.
- / Wet-Use Optimized: Specifically designed for wet coring applications to facilitate consistent water flow and slurry removal at depth.
- / High-Torque Durability: Built to handle the extreme mechanical loads required for drilling through heavily reinforced concrete and aggregate.
