For making small holes a revolver punch rod is often used, for larger holes a hollow pipe is used.
With this hollow pipe set, holes can be punched out of materials such as leather, rubber, cardboard, plastics and other thin, soft materials using a hammer. The hollow pipe has a short cylindrical space at the bottom of which the edge is sharpened, above that is the stem or shaft. To make a hole, the hollow pipe is placed upright on the material, and then a hammer is used to hammer it onto the shaft.
Made of high quality carbon steel.
The set contains hollow pipes with lengths from 80 to 115 mm and the following diameters: 2.5, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 11.0, 12.0, 14.0 and 16.0 mm.
