Milwaukee 7-1/2″ Extension for Small SDS Plus Thin Wall Core Bits

DEEP-REACH DRILLING FOR STRUCTURAL PENETRATIONS

When you’re dealing with thick concrete slabs or masonry walls that exceed standard bit lengths, you cannot afford a stall in production. This extension is engineered for heavy civil applications where deep-hole drilling is non-negotiable. Built from high-grade steel to withstand the constant vibration and torque of SDS Plus rotary hammers, it maintains structural integrity while pushing your thin wall core bits an additional 7-1/2 inches. It is the essential bridge for reaching the other side of a footer or conduit run without swapping to more expensive, oversized equipment, ensuring clean through-holes even in the most demanding jobsite environments.

• / High-Grade Steel Construction for maximum durability under high-torque drilling loads in reinforced concrete.
• / 7-1/2″ Extension Length provides the necessary reach for deep-wall penetrations and structural core work.
• / Seamless SDS Plus Compatibility ensures a secure, wobble-free connection to 8″ and 12″ adapter shanks.
• / Optimized Thin Core Design maintains high drilling speeds while reducing the load on the rotary hammer motor for better efficiency.
