A diamond drill bit is a helpful tool when it comes to making holes in hard non-wood surfaces such as ceramic, porcelain, glass, stone, marble and granite. Diamond drill bits get their extra cutting power from little pieces of diamond powder embedded in them. However, diamond core drill bits can be much larger.

Diamond is the toughest naturally occurring material. In addition, diamond is hollow, meaning water can be pumped through it effectively. This is also important for drilling as it allows us to perform wet drilling methods using diamond drill bits.

Heavy-duty drill bits – such as those used in the oil exploration industry to drill through rocks – are made with diamonds so that they stay sharp for longer. Diamond is insoluble in water. Every atom in a diamond is bonded to its neighbours by four strong covalent bonds, leaving no free electrons and no ions .

Diamond is a rare, naturally occurring mineral composed of carbon. Each carbon atom in a diamond is surrounded by four other carbon atoms and connected to them by strong covalent bonds – the strongest type of chemical bond.

Diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.

A gem is simply a hard substance, commonly a mineral, which has been cut and polished. Thus, yes, a diamond is a gem!

Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.

Diamonds remain the most scratch-resistant material known to humanity. The structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.
