United Abrasives 51354 Fiber Disc is a high-performance grinding solution designed for demanding metal fabrication and finishing tasks. Featuring a 5" diameter and 7/8" arbor hole, this disc is constructed with 9S ceramic grain bonded using a durable resin-over-resin system on a vulcanized fiber backing. Its coarse 50-grit abrasive allows for aggressive stock removal while maintaining consistent performance even under high-pressure applications. With a maximum speed of 12,200 RPM, the disc delivers fast cutting action and long life, making it suitable for use with standard right-angle grinders in industrial environments.
Engineered with a grinding aid, the United Abrasives Fiber Disc minimizes heat build-up and loading, ensuring cooler operation and preventing material discoloration—particularly important when working with stainless steel, titanium, aluminum, and other heat-sensitive alloys. Its ceramic aluminum oxide grain self-sharps during use, extending the disc’s efficiency and reducing downtime for replacements. Packaged in bulk spindles of 100 pieces, this fiber disc is an economical choice for high-volume users such as fabrication shops, welders, and metalworking professionals seeking precision, durability, and productivity in heavy-duty grinding operations.
