What is the Difference Between Type 1 & Type 27 Abrasives?

Type 1 and Type 27 grinding wheels are two different types of abrasive wheels used for grinding and cutting metal and other materials. The main difference between these two types of wheels is their shape and the tasks for which they are best suited.

Type 1 grinding wheels, also known as straight wheels, are flat and have a uniform thickness across the entire wheel. They are designed to be used on a variety of surfaces, including flat surfaces, edges, and angles. Type 1 wheels are commonly used for surface grinding, sharpening, and cleaning, as well as for cutting off small pieces of metal.

Type 27 grinding wheels, also known as depressed center wheels, are shaped like a saucer with a depressed center in the middle. They have a thicker cross-section at the center and thinner edges. This shape allows the wheel to be used at a slight angle, making it ideal for grinding and cutting on contoured surfaces and hard-to-reach areas. Type 27 wheels are commonly used for grinding welds, removing burrs, and shaping metal.

In summary, Type 1 grinding wheels are flat and used for a variety of grinding and cutting tasks on flat surfaces, edges, and angles. Type 27 grinding wheels have a saucer shape with a depressed center, making them ideal for grinding and cutting on contoured surfaces and hard-to-reach areas. The choice between these two types of wheels depends on the specific application and the type of material being worked on.
