A ring saw is a special type of saw that uses a stiff circular blade that is formed in the shape of a ring. These saws are designed to work in much the same way as a bandsaw. In essence, the blade of the saw is rotated around by a pair of wheels. As the blade rotates, it uses abrasion to cut through whatever materials it comes in contact with.
Ring sawing is beneficial for applications that require precision. The blade itself is quite narrow. As a result, the amount of material that is removed when using it to make a cut is negligible – especially when compared to the amount of material that is removed when using other types of cutting blades.
