Milwaukee 12″ Wet Core Bit Extension – Standard Duty (48-17-4040)

Description

MAXIMIZE PENETRATION DEPTH IN REINFORCED CONCRETE

When structural specs require deep-bore penetrations through thick-slab foundations or bridge decks, standard bit lengths often fall short. This 12-inch extension is engineered for heavy civil operators who demand rigid, high-torque performance when coupled with MX FUEL or high-amperage corded core rigs. Designed specifically for wet-use environments, it maintains concentricity under load, ensuring your path remains true even at extended depths. Proper maintenance is critical in high-torque applications; always apply anti-seize lubricant to the threads to prevent thermal locking during high-friction cycles in reinforced concrete.

• / Adds 12 inches of effective drilling depth for thick-wall and deep-slab applications
• / Optimized for wet-drilling to manage slurry and maintain bit cooling during deep bores
• / Precision-machined 1-1/4″-7 threads ensure seamless compatibility with Milwaukee Premium Wet Core Bits
• / Heavy-duty steel construction resists deflection under the high-torque demands of structural coring
