Milwaukee 2″ x 12″ Diamond Premium Wet Core Bit Extension

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.
