Improved Durability for Long Life
The nonwoven fiber material runs cool, resists loading, and holds up to edge work, while aluminum oxide abrasives provide effective cutting action that produces consistent finishing performance on stainless steel, aluminum and carbon steel over the life of the belt. All of our Scotch-Brite Durable Flex Belts can be distinguished by their purple backing.
Tough Aluminum Oxide Abrasive
This belt uses aluminum oxide abrasive. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is embedded in the nonwoven web, which wears away evenly to continually expose fresh mineral. 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.
Works on Multiple Tools and Machines
Scotch-Brite Durable Flex Belts work great on a variety of tools and machines, including file belt tools, inline sanders and backstands.
