Milwaukee 12" Core Bit Extension 48-17-4050
EXTEND YOUR REACH THROUGH DEEP STRUCTURAL CONCRETE
When punching through thick foundations or reinforced bridge decks, standard core bit lengths often fall short of the required penetration. This 12-inch extension is engineered for heavy civil applications, providing the necessary depth for utility penetrations and structural sampling without sacrificing the rigidity required for high-torque MX FUEL or corded core rigs. Designed specifically for wet-drilling environments, it maintains the structural integrity needed to withstand the constant friction and torque of deep-bore operations. To ensure maximum tool life and prevent thread seizing under extreme heat, always apply anti-seize lubricant before mating the extension to your bit.
- / 12-inch reach expansion allows for deep-bore applications in slab-on-grade or thick structural walls where standard bits cannot reach.
- / Wet-use optimized design ensures consistent performance and durability during high-volume water cooling and slurry management.
- / High-strength steel construction maintains concentricity, minimizing vibration and run-out at high RPMs for cleaner holes.
- / Universal 1-1/4"-7 thread pattern provides seamless compatibility with Milwaukee Premium wet core bits and professional-grade rigs.
