You can make holes. The hand-made steps of jewelry can be divided into five categories, namely, preforming, scratching, cutting, polishing and drilling. Mark the position before you start drilling. Punch a small mark with the center hole with a spring, or draw a point to be drilled with a scriber. When using the scriber, hold the scriber firmly on the metal by hand, and quickly stroke down, left and right. If a center punch is used, the drilled workpiece needs to be placed on a flat piece of metal, and then the center punch is placed on the workpiece and pushed down smoothly.
