The Groz Drill Chuck Arbors are essential tools for efficient and precise drilling operations. These arbors are designed to securely mount drill chucks and other tools with a female taper shank onto a machine equipped with a female taper socket in its work head. Made from high-quality Hi-Tensile Steel, each arbour undergoes a rigorous case hardening process that results in a hardness range of 54-58 HRC, ensuring resistance to wear and tear. 

Our Drill Chuck Arbors are also precision ground to close tolerances, with concentricity controlled to within 0.0004 inches and self-locking tapers that guarantee an accurate fit. With these features, our Drill Chuck Arbors are reliable and precise tools
