•Most general model : This chuck, with both KS and JIS Standard, is most widely used for general purpose lathes. A separate adapter is used when attached to a lathe. •High quality, long durability : Internal stress and deformation have been precluded by using high quality cast body. The major parts are made of heat-treated alloy steel. Good durability has been achieved due to extended abrasion resistance and improved quality. •Compatibility : Compatibility of major parts such as a jaw has been enabled thank to quality standardization and precise dimension mangement. •Parts : External jaws are attached to the chuck and internal jawss, fastening handles and mounting screws are included as standard parts.
