Using the Makita SC05340110 round punch is easy. First, make sure you have the 1/2 inch (13 mm) Makita Round Die (sold separately). Place the metal plate you want to punch holes in on a stable surface. Align the punch and die correctly with the spot where you want the hole. Then, use the Makita Cordless Metal Hole Punch model XPP01 to apply pressure and create the hole. When it comes to maintenance, after each use, wipe the punch clean to remove any metal shavings or debris. You can use a soft cloth and a little bit of oil to prevent rust. Store it in a dry place. Also, be careful when handling the punch as the edges can be sharp. Always wear appropriate safety gear like gloves and goggles when using this tool.
