4.5" x 7/8" Select Resin Fiber Discs, 040 Grit, Aluminum Oxide | LVARF45AO040SEL

Aluminum Oxide Resin Fiber Disc - Select Grade

These Lehigh Valley Abrasives branded Select Grade Aluminum Oxide Resin Fiber discs feature aluminum oxide grain bonded to a 0.8mm/0.6mm vulcanised fiber backing with a semi-open coat construction. The semi-open coat is engineered to resist loading when a single disc is run across mixed substrates, such as wood furniture components and soft metal, extending disc life across varied production runs. Jumbo coating ensures consistent grain coverage across the full face of the disc for uniform performance from edge to edge.

Primary Advantages of Semi-Open Coat Construction

• Semi-open coat actively resists loading on wood resins and soft alloys, addressing the dominant failure mode when one disc runs across both wood and metal substrates in a single shift.
• Reduces disc changes on mixed sheet metal and furniture production lines, improving throughput.
• Closed coat construction is not recommended for this application; semi-open coat is specifically engineered to prevent the loading issues closed coat discs experience in mixed-substrate use.

Primary Advantages of Vulcanised Fiber Backing

• 0.8mm/0.6mm vulcanised fiber backing provides the rigidity required for edge deburring on sheet metal without flex-induced chatter.
• Stiff backing construction supports consistent contact with the workpiece for predictable stock removal.

Primary Advantages of Jumbo Coating

• Consistent grain distribution across the disc face delivers uniform scratch patterns on furniture components ahead of finishing.
• Jumbo coated construction ensures even grain coverage disc to disc, reducing performance variability across a production run.
