Roll Lock Sanding Disc features an aluminum oxide abrasive, which is a popular choice among industrial professionals because of its 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.

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.

The greatest advantage of Roll Lock Sanding Disc is the use of Blue Lining Cotton Cloth sticked to the sanding cloth, that is to say there are 2 layers of polyester cloth.

Blue lining cloth used to enhance disc strength and friction between sanding disc and rubber pad holder to resist disc coming loose when operating.

Roll Lock Sanding Disc is a good first choice when working with steels, soft metals and wood.

Sharp Aluminum Oxide Abrasive:  Made from chosen sharp aluminum oxide abrasive which provides increased life, fast cut rate, consistent finish.

Advanced Grain Planting Technic: Dense aluminum oxide grain helps increase working efficiency and deliver better deburring or grinding results.

Heavy Duty X-wt Polyester Cloth Backing: Heavy duty X-weight 100% polyester cloth features flexible, high strength, good elasticity, heat resistant, corrosion resistant, wear-resistant and washable. It helps offering operational comfort and longer disc life.

Unique 2-Ply Polyester Cloth Back: The biggest difference and advantage between roll lock sanding discs of ours and others is the unique 2-layer polyester cloth structure. The other layer of Blue Polyester Lining Cloth is used to further enhance disc strength and reduce friction between sanding disc and rubber pad holder, to resist disc coming loose when operating which helps achieving longer lifespan and ensuring security. It also helps reduce vibration to make a clean cut and control the grinding performance.

Resin Over Resin Bonding: High strength resin bond system provides superior grain support, resist heat and humidity for longer life.

More Resin Adhesive Added to Resist Cloth Coming Loose:  Resin adhesive features heat resistance. More adhesive added to bond the cloth to the disc tightly, to resist cloth coming loose during operations.
