Scotch-Brite SE Surface Conditioning TN Quick Change Disc combines a coarse, nonwoven disc to perform heavy-duty deburring and finishing with the efficiency of a TN quick-change attachment. The heavy-duty nonwoven fiber construction conforms well to help preserve irregular or contoured surfaces and the TN attachment enables quick and easy disc changes.Ideal for Heavy Duty Deburring and Finishing The open-web fiber runs cool and resists loading while the aluminum oxide abrasives provide a high cut-rate for consistent finishing. The TN attachment gives you quick and easy disc change-out, making the Scotch-Brite SE Surface Conditioning TN Quick Change Disc ideal for heavy duty deburring and finishing. Versatile Aluminum Oxide Mineral Suitable for a Wide Variety of Substrates SE surface conditioning discs use aluminum oxide abrasive. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut-rate, hardness, strength and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys. The Many Benefits of Open Web Abrasives Scotch-Brite surface conditioning products were developed with abrasives incorporated into nonwoven nylon or synthetic fibers. Combining abrasives with the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material runs cool, reducing the risk of part discoloration and warping. The fibers are load resistant and keep the abrasive minerals cutting at high performance by limiting clogging of the fibers, which also extends the life of the disc.
