These green fibre grinding discs have been an industry staple for many years.
They are all-purpose grinding discs for any kind of metal or fiberglass grinding.
These long-lasting, fast-cutting, grinding discs use a premium aluminum oxide abrasive, putting them at the high end of 3M's general purpose disc spectrum.
• Used for grinding door skins, paint, rust, and weld removal and metal work
• A premium, general-purpose grinding disc
• Tough, but flexible, fibre backing
• Priced by the box
User Tip — Especially with coarser 36 and 24 grits, we recommend the use of an extra hard red ribbed backing plate for cooler running and prolonged disc life; see Related Products, below.
