• Quality zirconia alumina abrasive for good cut rate and life - at low initial price point • Type 27 Flat discs are designed to be used at a 0 to 15 degree angle on flat surfaces for blending and smooth finishing • Fiberglass/resin backing plates are the most popular due to high strength, light weight and ability to absorb vibration • Polyester/cotton backing combination for good cut rate and finishing • Extra coarse 36 grit for stock removal, beveling and edge chamfering
Flap discs are versatile grinding and finishing tools having four main components: abrasive flaps, flap density (how the flaps are stacked), backing plate shape (flat or conical), backing plate material (fiberglass/resin, plastic, aluminum). All flap discs have flaps that are overlapped and glued to the backing plate. The flaps wear during use, exposing new abrasive grain. The different variations of the components above provide a variety of choices ranging from heavy stock removal to blending to finishing. Flap discs are designed for portable grinder applications and can be the preferred choice over depressed center wheels or fiber discs.
