摘要

The present invention relates to a tough side punch that is used to improve air exchange and water flow through mechanical work on the soil of a golf course green made of turf, which has been condensed by pressing, and by improving the manufacturing process. It relates to a tough side punch that can be reused for a long time by increasing production efficiency and excellent abrasion resistance. In addition, the present invention manufactures a tough side punch in the form of a pipe by cutting (blanking) and bending (bending) an iron plate, and welding the close contact line part while covering a reinforcing tube or reinforcing piece to complete the tough side punch, characterized in that do.
