Graphite is commonly used as an abrasive, but diamond is not used. The number of neutrons in carbon atoms present in both graphite and diamond are the same. It only depends upon the nature of the element, and both are allotropes of the same element carbon.These covalent bonds are present throughout the surface giving it a very rigid 3-D structure. It is very difficult to break this extended covalent bonding and for this reason diamond is the hardest substance known. Thus it is used as an abrasive and for cutting tools.Cutting Tools for Graphite Machining
As previously mentioned, graphite is a notorious cutting tool-killer due to its extremely abrasive nature. Even the highest quality carbide end mills, if left uncoated, will wear quickly on most jobs.

What are the two uses of diamond and graphite?
The atoms in graphite and diamond are strongly bonded with covalent bonds, forming different arrangements with each other. Diamonds are used in Jewelry making, construction, minor industrial applications, and surgeries. Graphites are used in stationery, lubricants, industries, or nuclear reactors.
What is common between diamond and graphite?
The common thing in graphite and diamond is their crystalline crystal structure. This is because the carbon atom in both diamond and graphite are regularly arranged to make a crystal.

What is graphite used for?
Graphite is also used in pencils, steel manufacturing and in electronics such as smart phones. Perhaps its most important application is the lithium-ion battery, where graphite ranks above even lithium as the key ingredient. There is actually 10 to 30 times more graphite than lithium in a lithium-ion battery.
Why are graphite and diamond not similar?
Graphite and Diamond are different because they have different structures. Both have Giant Covalent Structures, resulting in very high melting temperatures. However each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard.
Which is used in pencils?
Pencils contain a form of solid carbon known as graphite. According to the book The Pencil by Henry Petroski, the graphite pencil was first developed and popularized in the 1600’s.
What are the two types of abrasives?
There are two types of abrasives: NATURAL and MANUFACTURED. Important natural abrasives, such as emery, corundum, and diamond, are used only in special types of grinding wheels and honing stones. Manufactured or Synthetic Abrasives are now considered superior if not as effective as natural abrasives.
Which one is not an example of abrasives?
Files are not abrasives; they remove material not by scratching or rubbing, but by the cutting action of sharp teeth which have been cut into the surface of the file, very much like those of a saw.
Which of the following is abrasive material?
Which of the following is regarded as a modern abrasive? Explanation: Boron carbide and tungsten carbide are generally regarded as modern abrasives. They are close to the hardness of a diamond, which is a natural abrasive. Boron carbide is used for polishing pastes.
What is the nature of graphite?
Graphite is a big covalent structure with each carbon atom joined with three other carbon atoms with covalent bonds. Each carbon atom is sp2 hybridized. These carbon atoms form a layer like structure with a hexagonal arrangement of carbon atoms. These layers have weak forces between them.
