Jaws are made of bearing steel with proper heat-treatment and are finished with grinding. They are strong against wearing and can maintain the precision for a long time of usage.
The sleeve is one-piece structure. The body and the key-holes are hardened.
The 100% runout checking is made and, therefore every YUKIWA chuck is reliable for its precision
