The spring constant of RX-SJV□□-C is as twice that of RX-SJ□□-C
：P＞D-0.03ℓ＝0	If P > D-0.03 for tip shape, D -0.01/-0.03 (press-in lead) is not included.
：P・K＞D-0.05ℓ＝0	If P ⋅ K > D-0.05 for tip shape, D -0.01/-0.03 (press-in lead) is not included.
L（60）B＝13 If full length is (60), tip length is 13 mm in all cases.

■Uses of punches with locating dowel holes
This type of punch is mainly used with dies for parts such as automobile bodies, in combination with a retainer that holds the punch. Rather than indirect positioning using the retainer dowel hole, these punches can be positioned directly using the dowel hole machined on the punch axis, improving die accuracy. These punches are particularly effective when used for die machining with NC machines. This type of punch can be also used with dies for the external panels of electrical appliances, either in combination with a retainer, or attached to the punch plate of an ordinary progressive die.
