Ordinary iron plate: 1.8mm, stainless steel plate: 1.2mm, copper, aluminum plate: 2mm, and plastic plywood cart: 2mm.
Adjustable cutting heads: There are two of them. The cutter head can be moved in any direction. It’s possible to use an 8mm electric or pneumatic drill, which can run at speeds of between 1500 and 3000 rpm. The minimum cutting radius is 12mm.
High quality stainless steel is used to make it strong and hard to break. It will last for a very long time.
With a wrench, you can change the tightness.
To make sure the arc cut surface is smooth and beautiful, a plate hole opener should be used. A 3 mm positioning eye should be drilled first, and then a 12 mm hole should be made to extend the cutter head into the hole. Cut the inside and outside circles.
If you’re cutting aluminum plates, you should add a lot of oil to the edge of your knife. Start by turning on the electric drill. When you start cutting, exit first and turn off the electric drill when you’re done. Perpendicular to the piece of wood or other material that will be cut, the cutting edge of the cutter bar must be. This will keep the cutter head from breaking.
To use an electric drill and a thin plate hole opener, insert the front end of the drill and the cutter into the round hole of the hole opener. Then, connect the cutter to the drill and lock it. Tighten the three branches on the shelf and the stud screw to keep the hole-opener shelf from sliding. Insert the ruler rod from the left to the right to put the needle up into the small square hole of the rack. Finally, the top screw can be adjusted and tightened to match the size of the arc cut, and the ruler rod is held in place. This is the last part of the process. To make sure that round holes are cut correctly.
Drill broke before I even used it on sheet metal.
