Home Miter Cutting Miter Cutting Miter cutting involves the cutting of metal parts at a certain angle. Metal Supermarkets offers miter cutting on different angles for metal shapes such as angle, tube and channel. The most common kind of miter cut is a 45° angle that is generally used to form a corner, just like a picture frame – although it can comprise any angle greater than 0°. Metal Supermarkets can provide miter cutting services at many stores through our network.
