1. First of all, we need to mark the position where the hole needs to be punched, and usually use a cross line to lock the position we need, so that the punched hole will not appear deviation.
2. Then put the whole piece of stainless steel plate in the radial drill for drilling, pay attention to check the instructions of the machine, and standardize the operation, so as not to accidentally injure yourself.
3. Align the drill bit with the small hole we have made, and rotate it clockwise, as shown in the figure below.
4. When drilling holes, use cold water to dissipate heat from the drill, as shown in the figure below.
5. After punching the hole, rotate the drill counterclockwise and take out the drill, as shown in the figure below.
