3M Standard Abrasives Quick Change A/O Extra 3 Ply Disc 526555 3 in60 TSM 50 per inner 100 per case

For heat-sensitive metals and difficult-to-grind metals, our Standard Abrasives(TM) Quick Change Aluminum Oxide Extra 3-Ply Disc incorporates a grinding aid to swiftly grind, deburr, and blend. For applications requiring a stiffer backing than our 2-ply disc, the 3-ply disc is heavier and offers longer disc life while still yielding to accommodate both flat and contoured surfaces. Grinding Aid Increases Versatility and Reduces Disc Wear The grinding aid on our Standard Abrasives(TM) Quick Change Aluminum Oxide Extra 3-Ply Disc enhances cut on heat-sensitive metals and exotic alloys, reduces disc wear and helps prevent part discoloration. Quick Change Convenience Offered in a range of sizes and grits for medium-pressure applications, the disc comes with either a TR or TS attachment. These quick change discs allow tool-free disc swap outs, maintain secure attachment at high speeds, and save operators time when switching between grades or applications. Choose the disc compatible with your TR or TS holder pad. TR discs have a nylon threaded hub that easily mounts to TR or 3M(TM) Roloc(TM) type holder pads with a turn of the wrist, and the TS system has a metal hub that securely attaches to its holder pad with a simple twist. Aluminum Oxide Suits Many Substrates Aluminum Oxide (AO) discs are a good match for operators who desire all-purpose versatility and economy. AO is a tough mineral that self-fractures to produce a fast cut while grinding, blending and deburring. It can be used on a wide variety of materials including ferrous metals and composites. For applications not requiring a grinding aid, try our standard 2-Ply and 3-Ply AO Discs, and when a more flexible edge is needed for steeper contours, choose our Standard Abrasives(TM) Flexible Edge Coated Disc (both sold separately). The versatile portfolio of Standard Abrasives(TM) Aluminum Oxide Discs helps to ensure that operators will find a disc that is well-suited to their project needs and applications.
