Because they have to get through the minerals and rocks in the earths crust.
the diamonds are the strongest natural material on earth. these drills can drill through anything
Geologists use drill bits with diamonds because diamonds are one of the hardest materials on Earth, making them effective for cutting through hard rock and sediment. The diamond-covered bits can withstand the high pressures and temperatures encountered while drilling into Earth's crust, allowing geologists to access subsurface samples for study and analysis.
diamonds are used for there strength and there ablity to remain sharp
Diamond-tipped drills can cut through any material, including diamonds.
because they are so hard
Diamonds are sold for large amounts of money. they are valued for the durability, shine and popularity. Also in saws and drills, as the durability allows for long lasting sharp drills.
These diamonds are very tiny and are of little use in other trades. They tip many drills and saws to enable them to cut stone and other similar materials.Diamonds are not all from Africa, by the way, many other countries such as Canada and Russia also produce diamonds.Another AnswerAbout 80% of all diamonds mined all over the world are industrial diamonds used to enhance tools.
Diamonds are the hardest substance on earth, making them the perfect drilling tool. Diamonds used in saws and drills are generally ones with imperfections, and would not make it onto a 15,000 dollar necklace.
There are all different types, carbite tips to diamonds
There is no standard for how deep a mine can go when it 'runs out' of diamonds. You can review the material, below, to understand more fully how deep the largest diamond mine drills into the earth. As well, alluvial diamonds -- diamonds pushed along by the flow of water over the tops of diamond-bearing volcanic pipes -- can be picked up in riverbeds in some places.
Diamonds are used in the tips of drills and cutting equipment because diamond is that hardest mineral known. Seventy-five percent of all diamonds mined fit in this category of use. Diamonds are also used in jewellery such as diamond rings and diamond necklaces ,because they are very shiny (due to the way their surfaces are cut) and expensive, because only 25% of diamonds mined are gem-stone quality.
