Milwaukee 1-1/2" x 12" Diamond Premium Wet Core Bit Extension 48-17-4015

EXTENDED REACH FOR DEEP-SLAB STRUCTURAL BORING

When your core rig hits the limit on thick bridge decks or reinforced structural foundations, the Milwaukee 48-17-4015 provides the critical 12-inch depth expansion required to finish the bore. Engineered for the high-torque demands of heavy civil infrastructure projects, this extension maintains strict concentricity to minimize run-out and vibration during deep-hole applications. Designed specifically for wet-coring environments, it ensures a reliable connection between your rig and Diamond Premium bits, allowing for continuous water flow and debris evacuation in the toughest aggregate.

• / 12-Inch Depth Expansion allows for deep penetration in thick concrete slabs and structural footings.
• / 5/8"-11 Thread Pattern provides a secure, industrial-grade interface for 1-1/2" diameter core bits.
• / Wet-Rated Performance optimized for constant water cooling during heavy-duty masonry and concrete drilling.
• / Heavy-Duty Steel Construction prevents flexing under load to ensure straight, accurate holes at extended depths.
