From each end of the markings made, make small indentations with a drill, then between them you will need to make a notch with the help of a grinder. To prevent the drill from “running” on metal, you can first make light dents with a core and a hammer. For drilling, it is important to choose a drill of the appropriate diameter, it should be taken 2 mm larger than the thickness of the lock.
  • Cut a hole for the lock. Connect the drilled edges with lines. Now you have to work with a grinder, it is better to use a small tool. If the door is made of a profile, then you will need to cut a hole on both sides. For such work, a small grinder is the best fit.

After the slot is made, remove the metal, insert the lock (try it on), if necessary, then bore the hole to the required dimensions. This can be done with a drill equipped with a small abrasive wheel. The cylinder should fit well into the lock.
  • Make holes for fixing the handles. It’s simple: just drill the holes of the required diameter.
