We used aluminum oxide abrasive, which is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
Heat-resistant resin is a sturdy binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions of high heat or pressure. Cloth-backed discs are known for their durability and flexibility. They’re a good first choice when working with metal or for heavy wood stock removal.
