Milwaukee 1" x 12" Diamond Premium Wet Core Bit Extension Core Drilling 48-17-4010

DEEP-REACH STRUCTURAL PENETRATION FOR HEAVY-DUTY CORING

When you're punching through thick bridge abutments or deep foundation footings, a standard core bit often stops short of the required depth. This 12-inch extension is engineered for the high-torque, high-pressure environments of heavy civil jobsites, allowing you to reach deeper without sacrificing the stability of your bore. Designed specifically for wet-coring applications, it maintains structural integrity under constant water cooling and slurry exposure. Ensuring a clean, vertical path through reinforced concrete requires precision, and this extension delivers the rigidity needed to prevent bit walking or excessive vibration when paired with MX FUEL or high-output corded rigs.

• / 12-Inch Extended Reach: Provides the necessary depth for deep-bore penetration in thick structural slabs and utility vaults.
• / 5/8"-11 Thread Connection: Precision-machined to ensure a secure, high-torque link to Milwaukee Diamond Premium Wet Core Bits.
• / Wet-Application Optimized: Engineered to withstand constant water flow and slurry management in heavy-duty coring environments.
• / High-Strength Steel Construction: Built to handle the rigorous output of MX FUEL equipment without deflection or thread galling.
