■ Characteristics Standard Type ① The fitting sections (S) can be long up to V × 10. ② Precision wire cutting is used to make the S dimension longer. ③ A softened layer in the bore made by wire cutting is removed by polishing. (Tolerance of dimension V is the value after polishing.)

Head thickness 4mm type A straight core sleeve 4mm thick head type is a standard type that matches a core pin standard counterbore dimension of 4mm. It is possible to unify the counterbore of the plate to 4 mm. For core pins that are set inside the core sleeve and used, use alteration "Head thickness change (TC2)," or use a head thickness of 2mm.
