The shape precision standards for block bunches were modified in 2007 in order to meet the needs of higher precision dies.In addition, several types of shape tolerance standards are available to suit different customer applications. (These are selected by alterations.)

1)Shape precision standards

Item		Standard
Perpendicularity		a≤0.005
Parallelism		b≤0.005
Warpage		c≤0.005
Bending of tip		d≤0.01
Perpendicularity of top face		e≤0.005

2)Variations of shape tolerances(alterations)

Code	None	VKC	VKM	VHM	VHZ
Shape tolerance	V·H	V·H	V·H	V·H	V·H±0.005

Spring reinforced jector punches have been added to the block punch product lineup.
The spring constant is twice that of a conventional jector punch, providing improved scrap removal effects.

Applicable products: All jector punches
Can be used with L≥60.
Cannot be used for H6(With a jector straight punch, cannot be used for W≤6.00.)

How to order
The tip position can be set freely within the range of shank V and H.

Key groove position and flange position can be set freely.(For types with flange thickness of 10mm, the positions are fixed.)

With key groove	Single flange·flange stopper	Double flanges

• By default, the key groove, head, and flange are located at the standard positions(0). The positions can be changed at no charge.

  

• By default, the corners are rounded to 0.2 or less. If R0 is needed, specify R=0.
  R=0 cannot be selected with WPC treatment or HW coating types.

  

Material Hardness	Catalog No.
	Type	Tip shape	B Tip length
(H3~5) M2 61~64HRC (H6~30) D2 Equivalent 60~63HRC	HP		S L Tip length(B) L>S
M2 61~64HRC	HSP (H6~30)
Powdered high-speed steel 64~67HRC	PHP
Even when P=V and W=H, the tip tolerance is determined by the P and W tolerances.
