Our 3M™ Cloth 577F products feature alumina zirconia abrasive grain for increased cutting efficiency over aluminum oxide, and is backed with a heavy, water-resistant polyester backing that stands up to high-pressure applications and edge work. The durable backing ensures long life and supports both wet and dry operations.
Alumina zirconia mineral cuts faster than aluminum oxide across all metal types
3M™ Cloth 577F abrasives are recommended for use on aluminum, mild steel, and stainless steel or other exotic metal alloys for dimensioning parts, deburring, blending, and finishing castings and forgings. To protect heat sensitive alloys such as stainless steel, nickel alloys and cobalt alloys, we incorporated a grinding aid to reduce running temperatures. Additionally, the abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure.
