Rohm Keyless Drill Chucks from the Spiro and Supra series are precision toolholding solutions designed for fast, secure, and highly accurate drilling in professional workshop and industrial machining environments. Featuring advanced self‑tightening mechanisms, these chucks automatically increase gripping force as drilling torque rises, ensuring dependable bit retention without the need for a chuck key.
Renowned for their concentric accuracy and build quality, Rohm keyless chucks are widely used on drill presses, milling machines, and machine tools where repeatability and reliability are critical. With both taper‑mount and threaded options, these chucks support a wide range of machine configurations while delivering smooth operation, reduced runout, and consistent drilling performance. The Spiro and Supra ranges are particularly valued in production and toolroom applications requiring quick tool changes and high precision.
