The SWAG knock out punches can effectively eliminate all the problems commonly associated with inexpensive hole saws. The SWAG knock out punches are capable of cutting up to .1875" aluminum and or .125" mild steel, .083" chromoly, & .083" stainless.
Made in the USA out of domestic steel. These knock out punch dies are CNC machined out of 4130 quenched and tempered chromoly steel then heat treated hence their brownish/orange tint. Simply put, these punches are the highest quality dies that we can produce.
These knock out punches are pressed together using a 10 Ton Hydraulic Knockout Punch Driver as shown in the 2nd picture above. Not sure what one is? Check out Ebay or Harbor Freight, they sell for ~$100.00 shipped to your door step and they are a real time saver if you are dimpling a large number of items or hard to reach dimple die locations, it included a manual hand pump to apply hydraulic pressure to the punch set. The knock out punch set is a quality product as we have dimpled thousands of holes for years using this set up.
