Drilled punches

This type is popular.It is possible to wedge foam, rubber etc. into the drilled punches. The cutting lines are better than if using the Feed Through Punches and Side Ejector Punches. The knife is about 0.7mm thick (fromφ30 or more, the knife is 1.0mm thick).The one-sided knife is the same thickness.(The spacing rule of standard dimensionsis 0.5mm)
 

These are the punches with springs inside.Spring punches are favorable as rubber wedging is not necessary. They are more expensive than the common drilled punches.The diameter is from φ1 to φ15. The odd φ can be created.
 

The cutting line is very nice due to the rounded head design. It can be used in the same way as the Drilled Punches. The welding joints can be opened. It is suitable for foam or thin rubber materials.
 

The punch has straight and thick pipes. They are suitable for hard and thick materials. The waste material iscollected inside the pipe, this makes it convenient. They are more expensive than the common drilled punches. The common drilled punches have better cutting lines. The diameter is from φ1 to φ40. (From φ13 or more, the spacing rule of standard dimensions is 1.0mm).
 

This type is a modification of the Feed Through Punches. As the waste material is collected from the side of drilled punches, the punches are made much more than Feed Through Punches. The feed box must be put on the base of the side ejector punches. This type is a lot more expensive. The diameter is from φ1 to φ10. The type of φ11/ φ12 should be ordered separately. For larger punches, we cannot make the feed box of 23.6 in height.
