Mount drill chucks directly into high-speed CNC machine tool spindles with industrial-grade Steep Taper Arbors (steep taper drill chuck arbors). Manufactured for seamless compatibility with standard steep taper spindle interfaces (such as SK, BT, and CAT standards according to DIN 69871 and MAS 403 BT), these precision adapters feature a steep taper body on one end and a standard drill chuck taper (B-taper / Jacobs taper) on the front. Case-hardened and precision-ground to ultra-tight runout tolerances, they ensure maximum rigidity, excellent dynamic balance, and vibration-free torque transmission during heavy drilling and reaming operations on CNC milling centers.
