Type 29 Alumina Zirconia Abrasive
3M 566A Flap Discs are used on rotary angle grinders for stock removal and finishing applications on mild steel, non-ferrous metals, and stainless steel. They provide a versatile, one-disc system for metal fabrication applications where more durability is needed for medium-weight grinding, small weld removal, finishing, and surface preparation.
Run on a right angle grinder, flap discs are a one-step alternative to bonded wheels and fiber discs.
A lighter backing than the 577F discs allows these discs to "break down" faster - exposing new abrasive material for less waste - letting you use up the entire disc.
The alumina zirconia abrasive on these discs is a step up from aluminum oxide flap discs, and is an inexpensive alternative to 3M's better performing 700 series Cubitron and premium performance 900 series Cubitron II flap discs.
Durable YF weight polyester backing for long life under heavy-duty grinding use
Note Flap discs typically provide a finish that is one grade finer than their actual rating
