Milwaukee 12" SDS-Plus Extension for Thin Wall Core Bits 48-03-3561

EXTENDED REACH FOR PRECISION MASONRY CORING

When your standard bit length falls short of the breakthrough, the Milwaukee 48-03-3561 extension provides the necessary reach without compromising the mechanical integrity of your SDS-Plus system. Designed specifically for thin wall core bits ranging from 1-3/4” to 4”, this extension maintains strict concentricity to prevent bit walking and excessive vibration during high-speed rotation. The forged steel construction ensures that the impact energy from the rotary hammer is efficiently transferred to the cutting face, maximizing your drilling speed and extending the life of your core bits. For professionals managing deep-wall penetrations or tight-access MEP installations, this extension is a critical component for maintaining jobsite productivity and achieving clean, precise holes in masonry and concrete.
