●Applicable range
1.Hole diameter:φ1.0~φ16
2.Workpiece material: Can be used for materials up to a maximum tensile strength to 1,177N/mm² (120kgf/mm²).
3.Thickness of workpiece material: Minimum thickness 0.15mm
4.Scrap retention effects cannot be expected when the clearance(C) is larger than the workpiece material thickness(MT) by more than 20%. Therefore, keep the difference to 20% or less.
Clearance on one side (C)<Workpiece material thickness(MT)×20%

Because scrap retention block dies prevent scrap lifting by forming small projections on punching scrap, they are not suitable in cases such as punching of precision holes, or when the punched-out item becomes the product.
