Small diameter Type High precision High retentivity SRE SRS Slim Type High precision Shrinker chuck for cutting tool with a shank diameter of φ3-8. To be heated by induction heating device IH1500. Collet Holder Shrinker chuck High retentivity Slim design SRD High precision High retentivity High rigidity Advantages of Shrinker Chuck High retentivity The chucking torque is 2 - 4 times higher than that of Collet Holders. Cutting tools with short shanks can be used. Superior Rigidity Increased rigidity, feed rates, speed, and longer tool life is acheved.
