I'm selling this, which I purchased but haven't been able to use up. Below is the product description from that time: This is a hand press machine compatible with tools up to 13mm in diameter. It can be used for things like diamond chisels, hole punches, rivet setting, and snap fasteners. If you want to use tools larger than 13mm in diameter, you can insert a bolt and nut into the hole and use the head to press the tool. The height is adjustable up to 20cm, and the stroke can be adjusted up to 3cm, making it a versatile item. It uses wing bolts, so you don't need a spanner or wrench; you can tighten and loosen the bolts by hand. When setting rivets or snap buttons, using a hammer can be noisy, and you have to be mindful of your surroundings and the time of day. However, this machine makes no noise, so you can work anytime without worry. Also, even when you can't set rivets properly no matter how much you hammer, this machine can set them in one go, making the process easier. Although it's an industrial product, it has various adjustments, so it's very useful for handmade crafts. For leathercraft diamond chisels, you can punch the diamond shapes at the same height, resulting in evenly sized holes and a beautiful finish.
