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 After the hole opener drills through the workpiece, the workpiece should be withdrawn while the hole opener is rotating.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. Hex shank is made of solid hardened steel, with high hardness. Can be used in drill press, bench drill, vertical drilling machine, CNC carving machine. Two spurs and centering point can offer repeated, clean and accurate cutting holes. The sharp center spur accurately locates the center of your hole. Small incision resistance to improve the opening speed. The head adopts arc curve design for easy chip-removal and no tremor. The perforation is neat, smooth, no broken edge. Processing hardwood or other hard materials should be injected with water to improve the quality and accuracy of drilling, and extend the life of the hole opener. The tool edge and tip should be sharpened in time if they are worn or damaged, or the tool will be damaged quickly. Can not drill metal and non-ferrous metal, otherwise the hole opener will be damaged quickly. The cutting material must be fixed, and the drill bit should be perpendicular to the material. It will damage the tool or the material if the cutting material moves during the drilling process.
