Diamond drills can be used in a rotary tool such as a Dremel or in a drill press for making small holes through stones. Using a drill press is easier to keep the bit straight and avoid breakage.
You will need to drill a hole to hang a stone by a cord, leather or jewellery finding. Always use a coolant (usually water) when working with these drill bits. This will help increase the life of the drill bit and give you better value. We also recommend that you wear eye protection such as safety glasses.
Do not force the drill bit, let the diamond do the cutting and drill at a slow to moderate speed. Drilling too fast will just wear off the diamond plating prematurely. Take the drill bit out of the hole you are drilling frequnetly and flush with water to remove debris. Resharpen occasionally using an old carborundum wheel.
