Square Pads, also called square cartridges, are an aggressive product used for weld removal applications on inside corners where resin fiber discs and flap discs cannot reach. Square Pads are an excellent product choice to be used in ID (inner diameter) tube polishing. Similar to cartridge roll, the cotton backing cloth of the abrasive is designed to break down during use revealing the next layer of abrasive. As the breakdown process occurs, it exposes new sharp grains to continue the even finishing process.
