Milwaukee 2" x 12" Diamond Premium Wet Core Bit Extension 48-17-4020

MAXIMUM DEPTH REACH FOR STRUCTURAL CONCRETE CORING

When the job requires penetrating thick structural slabs or deep footings that exceed standard bit lengths, the 48-17-4020 is the essential link in your coring rig. Engineered to handle the high-torque output of MX FUEL and corded core drills, this extension maintains concentricity and power transfer through the toughest reinforced concrete. Proper maintenance is key in these high-friction environments; always apply anti-seize to the 1-1/4"-7 threads to ensure easy breakdown after a long day of wet-cutting and slurry management.

• / Extends core bit drilling depth by a full 12 inches for deep-bore structural applications.
• / Precision-machined 1-1/4"-7 threads provide a secure, high-torque connection compatible with Milwaukee Premium Wet Core Bits.
• / Heavy-duty steel construction ensures minimal runout and maximum durability under extreme jobsite loads.
• / Optimized for wet-use environments, facilitating consistent water flow and slurry removal during deep-hole drilling.
