To the left is an image of a straight wheel. These are by far the most common style of wheel and are commonly found on bench grinder. They are used on the periphery only and therefore produce a slightly concave surface, this can be used to advantage on many tools such a chisels

Diamond wheel

At right is a diamond wheel, these have industrial diamonds bonded to the periphery, they are used for grinding extremely hard materials such as carbide tips, gemstones or concrete. The saw pictured is a slitting saw and is designed for slicing hard materials, typically gemstones.

Cut off or parting wheels are self sharpening, they are thin in width and often have radial fibres reinforcing them. Often used in the construction industry for cutting reinforcement steel (rebar), protruding bolts or anything that needs quick removal or trimming.
