Package list:
1 * Punch Disc How to Use Instructions for use: When using, please lay the puncher first. The metal sheet to be punched is first quenched and annealed, and then placed in water to cool suddenly. Then take out the punch of the puncher, and put the metal sheet in the middle gap. If necessary You can add two drops of glue to hold the metal piece in place and scrape it off after you’re done. Then align the desired hole diameter, the plane of the punch is down, and the chamfer is up, and the metal sheet can be pressed against the metal sheet with a large hammer and beaten vigorously to form a sheet.[Note: If you use a manual hammer, the hammer head should be large and the force should be large. Try to do it with one hammer, otherwise it will easily cause spy images or uneven edges. You can also use a hydraulic press to save more effort. The cross section of manual punching will have some traces, which can be polished and trimmed again]
