Diamond drill bits are a helpful tool when it comes to making holes in hard non-wood surfaces such as ceramic, porcelain, glass, stone, marble and granite. They get their extra cutting power from little pieces of diamond powder embedded in them. These drill bits, whether twisted or cylindrical, are particularly useful in bathroom applications where you have to drill through tiles to mount towel racks and vanities. Some diamond drill bits require water or another coolant to lubricate the bit as it makes its way through tough materials.
Diamond drill bits come in range of sizes, typically up to about 2 inches (5 centimeters). The smallest ones are used by jewelers and watchmakers to make holes in beads and other hard surfaces. However, diamond core drill bits can be much larger. Core drill bits are hollow in the middle and drill by cutting a hole out of the material being drilled. When it comes to choosing the right diamond drill bit, different factors come into play, including the material you plan to drill and what kind of hole you need.
Before you select a drill bit, you will have to decide what material you are going to drill. This type of drill bit is commonly used to drill rock, glass, tile and other hard materials, and even for diamond drilling. The shape of the drill bit you need to use will depend on what it is you will be drilling.
You should also consider buying your drill bit from a whole dealer. Since they do not last too long due to the wearing off of electroplated diamonds from the heat that is generated during the drilling, it may better to purchase one that is not too expensive. If you can get a good deal for one that is of great quality, it is more advisable to go for it as you will need to replace it after a couple of uses.
Lastly, refrain from buying the first diamond drill bit that you see. There are labels that can help you to decide which one is best for you as the purpose of that drill will be clearly stated.
