These diamond drills come complete with a drill guide & water cooling system. You can fill the plastic reservoir with water to keep the drill cool whilst drilling. Complete instructions on how to use the water reservoir tool are included on the product packaging. A cordless drill is recommended when using the water reservoir, take extra care when using a drill with water.

For best results the drill requires lubrication. If you choose not to use the water reservoir tool included, pour a small amount of water onto the surface before drilling. Use with a high speed drill, ideally 800 to 2000 rpm and use only light pressure.
