Keyless integral drill chuck, clamping capacity from 1 to

【Self-Locking Jaws】The self-locking jaw mechanism automatically tightens the clamping force as the rotational torque increases, preventing drill bit slippage during intensive milling operations, without the need for manual adjustment with a wrench.
【Integrated Cylindrical Shank】The integrated cylindrical shank construction forms a single solid block with high concentricity, eliminating imbalance and ensuring stable and accurate drilling on lathes and milling machines.
【Hardened 40Cr Steel】The key components of the jaws and body are made of 40Cr steel, hardened by a specific heat treatment, achieving a hardness of 40HB, resisting deformation under high fatigue stress and extending tool life.
【Precise Clamping Range】The precise clamping range securely holds cylindrical shank drill bits from 1 to 13 millimeters, providing a versatile holding solution for a wide range of tooling diameters in a single tool. chuck.
【Direct machine mounting】The APU13-MTA4 shank taper allows for direct and rigid mounting on compatible milling machine spindles, reducing tool overhang and increasing machining rigidity.
