Note
- When drilling, make the drill bit perpendicular to the object. Ensure that the drill bit and the workpiece are stable, and pay attention to the inclined position that is easy to break.
- When using drill bits with electric drills, it is recommended to use them at low speed and low weight on bit. The thicker the drill, the slower the recommended speed and pressure. To avoid breaking, it is recommended to use 1/16 inch and smaller drill bits for flat-nose pliers.
- Manual measurement, please allow slight errors.
