A grinding wheel is a wheel used for grinding. Grinding wheels are composed of abrasive compounds and are used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines. The wheels are generally made with composite material .
Drills are cutting tools used to remove material to create holes, almost always of circular cross-section. Drills come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.
In addition, there are many ways to distinguish, for example, according to the type of grinding tools used in grinding: the grinding method of fixed abrasive abrasives and the grinding method of free abrasives.
