Description

Product description Product Description INSTALLATION Make sure that HXIN VB diamond drill bit is firmly screwed into the M14 thread and that the flange cannot move. If there is over-filling wax inside, please use a wrench to screw it into, even if the over-filling wax is squeezed and come out! FIRST AND SECOND STEPS First Step: Make a guider at the location At the beginning, please tilt about 10° - 45° to start drilling. It will help to drill a shallow groove which can be used as a guider. Second Step: Drill the hole vertically After making the shallow groove, you can drill the hole vertically. The shallow groove can help you to prevent the sliding of the drills during drilling and make the location. We suggest you sway the machine slightly, so that the powder of stone can be got out easily. It can prevent the powder stucking in the hole and making high heat. In this way, it will extend the working life of HXIN VB diamond drill bit. THIRD STEP Third step: Drilling and Swing While drilling holes, always sway the machine slightly. In order to make HXIN VB diamond drill bits last longer, please follow the correct instructions of the method of use. 1. Do not use the hammer mode of the machine. 2. Before drilling again, we must make sure that the drill bit is properly installed on the machine, firmly without vibration. 3. The bit must be clean and free of any obstructions. 4. While drilling, you only need to apply light pressure.(The pressure of the weight of the machine will be enough in the vertical direction). Review: Great tool - I use these all the time to drill in tile, stone, etc. using this model that fits a grinder is way better than using a drill. Try one and you’ll never go back. Review: Not worth it - After using it on one job to cut porcelain it’s completely useless, al of the diamonds are gone
