1. Before perforating, prepare yourself for safety. Please wear loose clothing, a hat, and protective gloves. Always put security at the forefront. Make sure the stainless steel is in a safe place. The stainless steel clip should hold securely. Without the clamp tightening, it can move, rotate, and lift while perforating, and in severe cases, it can be secured safely.

2. Mark X points to the machined material to make it easier to find where to perforate. If you are worried that the stainless steel surface will be scratched when the electric drill rotates, you can cover it and mark it with tape.

3. When using a hole punch, use the center punch to quickly make the stainless steel indentation and hold the bit firmly to the mark, or use a hammer and drill to hit the mark once or twice. Create a small depression. This also prevents the bit from slipping on the stainless steel while perforating.

4. If the diameter of the hole to be drilled exceeds 8mm, it needs to be drilled back and forth. When drilling, install a drill bit half the diameter of the desired hole. If an 8mm hole is required, drill a 4mm hole, then install the 8mm drill and start over. For thin metals such as those less than 3mm thick, a single drill can get the job done, but when drilling holes in the material with the drill you need to make sure the holes don’t bend and spiral.

5. Drizzle lube into the grooves of the punch and start drilling with the drill bit perpendicular to the bracket. This prevents noise. When using a drill, pull the trigger slowly until the drill starts to spin. Drilling is done without additional lubricant noise while preventing the drill tip from heating up.

6. During the drilling process of stainless steel processing, if excessive pressure is applied, the friction will cause the drill bit to become hot and red, thus damaging the drill bit or the stainless steel material. If the rotation speed is slow enough and there is enough lubricant, this will not happen, and the pressure will increase the cooling time of the drill bit.
