Instructions for Woodworking Hole Opener 1. Put the hole opener into the electric drill before use and confirm that it is firmly clamped before it can work. 2. Keep the vertical angle with the workpiece when working. After the hole opener drills through the workpiece, the workpiece should be withdrawn while the hole opener is rotating. Please clean the sawdust in time to avoid opening failures during continuous work. 3. Workers should wear corresponding protective equipment when working to protect them from working safely, and apply rust oil after use to extend the service life.
