Abrasives and high speed drills are often made of carbide alloys of carbon and various metals.
There are a couple of elements that are mainly used in high-speed drills and abrasives. These elements are tungsten and diamond, or carbon.
Carbon, in the form of diamonds. Ground-up garnets are also used, in the form of a coating stuck to abrasive materials such as disks for angle-grinders and the best kinds of "sand-paper".

Abrasives are typically used in something that is being roughed up for a variety of reasons. Vitrified bonded abrasives are an abrasive that are made of either clay or ceramic.
Some common drills used to drill into the earth include rotary drills, percussion drills, and auger drills. Each type of drill is designed for specific geological conditions and depths, with rotary drills being the most versatile and commonly used for deep drilling.
Silicon is the second most abundant element in Earth's crust and is the principal component of sand and quartz. It is widely used in various applications including solar cells, computer chips, caulking materials, and abrasives due to its semiconductor properties and abundance.
Abrasives are materials that are used to abrade or "sand" surfaces. A wide variety of materials are used as abrasives. Some are hazardous, like sand which contains crystalline silica, while others are not hazardous, like ground walnut shells.
As gemstones, abrasives, and in lasers.
Most likely, you mean silicon. It is certainly used in computer chips, glass, and abrasives.
High Speed Steel is mostly used for manufacturing various cutting tools such as drills, milling cutters, saw blades, knives etc.
Exercises that may be used for soccer drills are speed ladders, hurdles, cones, lateral side steppers, resistance sleds, resistance harnesses, wobble boards and reaction balls.
Diamond is used for gemstones, abrasives, and saw blades.
