Why is diamond used as a cutting tool?
The rigid network of carbon atoms, held together by strong covalent bonds, makes diamond very hard. This makes it useful for cutting tools, such as diamond-tipped glass cutters and oil rig drills. Like silica, diamond has a very high melting point and it does not conduct electricity.
What are diamonds used for cutting?
Diamond excels in “hardness” and “heat diffusibility” as a cutting tool material. CBN, with hardness akin to that of diamond diamond is mainly used for cutting ferrous metal thanks to its lower reactivity than diamond with ferrous metal. Both materials can be polished to form “sharp cutting edge.”
Is diamond good for cutting tools?
Diamond is extremely hard and has a high melting point. For this reason, it is very useful in cutting tools.
What is diamond used for?
They are known particularly for their use in jewelry, such as rings or necklaces, because of their durability and their luster. However, most diamonds are used industrially. Because of their hardness, diamonds are extremely useful when used to cut, grind, or drill other materials.
Can diamond cut diamond?
Using these imperfect stones as cutting grit belies the main theory: only a diamond can truly cut another diamond. Diamonds are cut with specialized tools that make use of diamond tipped phosphor bronze or diamond dusted steel blades.
Is diamond used to cut steel?
Diamond, if you don’t know already, is the hardest naturally occurring substance known to man, which is why it’s used to cut hard materials like tile, steel, and concrete. On the mineral hardness scale, diamond comes out on top, have a rating of 10 on the Mohs Hardness scale.
Can diamond cut glass?
Yes, diamonds (diamond is a 10 on the Mohs scale of hardness) can cut glass (glass is a 6 – 7 on the Mohs scale).
Why diamond is used in cutting and drilling tools Class 10?
As diamond is extremely hard, it can be used to cut and grind other hard materials or metals. Hence, it is used in rock-drilling equipment to drill holes in the rocky layers of the Earth. Graphite being soft cannot be used to cut or grind.
