DUSS Diamond Core Drill Bit Extension:300mm x 1 1/4"UNC Female

This diamond core drilling accessory is a 300mm extension designed to connect a 300mm diameter core bit to drilling equipment. It features a 1 1/4 inch UNC female thread, which is a standard imperial thread type for heavy-duty industrial drilling applications. The primary function of this component is to extend the reach of the drilling setup, allowing operators to core through thicker materials or access deeper bore holes without modifying the main bit. Buyers select this specific extension when their existing rig or stand requires a longer connection length to accommodate their drilling depth requirements. The nominal length designation in the supplied data appears to indicate a specific unit or configuration rather than a physical measurement in standard linear units, so purchasers must verify the exact physical length against their rig specifications to ensure proper fitment and operational clearance.
