It is a known fact that diamond is one of the strongest materials in the world and is almost indestructible. Hence, it comes as no surprise that cutting tools often have diamonds in them. As a matter of fact, Diamond Dressing tools are considered just as valuable as the machines that are fabricated using.
When we say diamond tools, it does not mean that big diamonds are used to create these tools. People who use diamonds to create jewellery will actually cut the big translucent rocks to small sizes and then carve them into the appropriate shape. The residue would include smaller stones and grit, and it is this that is used to create such cutting tools. The tiny pieces of diamonds will be fitted into the tips of these cutting tools, and given their strength and hardness, they will be able to cut through the strongest of metals and materials.
Similarly, Diamond Grit also finds industrial uses, especially when it is ground into a fine powder and then converted into a paste. This paste, when diluted with some water, makes for a great way to return the shine to surfaces such as glass.
