Your drill is a versatile tool — but only when you’re properly equipped with the right kind of drill bits for the job at hand. If you need to drill particularly hard non-wood surfaces, then you’re going to need a tougher drill bit. A diamond drill bit is the best choice for these materials. Diamond drill bits have small pieces of diamond powder embedded, and they can tackle drilling on ceramic, porcelain, glass, and even stones like marble and granite. They’ll work with water or other lubricating coolants, and they’ll make drilling through tough items easy work. But there are a lot of choices when it comes to diamond drill bits.
