12" Core Drill Bit Extension Rod – Standard 1-1/4" Male & Female Threads, Heat-Treated High-Strength Steel, Perfect for Handheld Core Drills & Core Drill Rig with Stand, Extend Reach for Deeper Holes

Core Drill Bit Extension Rod: Precise Adaptation for Expanded Working Range： It adopts a standard 1-1/4"-7 interface, with both ends accurately connectable to core drilling rigs and drill bits. It easily achieves a 12-inch extension, allowing you to expand the construction range without additional tools in deep-hole operation scenarios such as ceilings and high walls, and efficiently complete various drilling tasks.

Wide Compatibility, Multiple Machine Adaptation： Specifically designed for diamond core drilling machines, it is compatible with the vast majority of core drills of the same specification on the market. No need to worry about equipment compatibility—one purchase fits your existing drilling tools, reducing equipment investment costs. Suitable for handheld core drills (limited to bits under 3") and core drilling rigs with stands.

Core Drill Bit Extension Rod： Made of high-strength steel, it features excellent torsion resistance and wear resistance, capable of withstanding the strong torque generated by core drilling rigs during high-speed operation. Even when used for long-term drilling in hard materials such as concrete and stone, it is not easy to deform or wear, and its service life is far longer than that of ordinary extension rods

Easy Installation, Time and Effort Saving： It adopts a quick-install design, allowing connection and disconnection between core drilling rigs and drill bits without complex tools. Even novice operators can master it quickly, which greatly saves installation and debugging time and improves work efficiency

Excellent Craftsmanship, Strong Stability： The rod body undergoes precision machining, featuring high straightness and maintaining stable concentricity during high-speed rotation. It effectively avoids problems such as drilling deviation and drill bit damage caused by vibration, ensuring each drill hole is precise and smooth, and meets the strict precision requirements of professional construction.
