Norton Part # 66623399033
• Alternating zirconia alumina (blue) and aluminum oxide (black) flaps provides higher performance than aluminum oxide while retaining an economical price
• Type 29 have an angled face providing greater surface contact and are the best choice fast stock removal
• 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
• Coarse/40 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. Package of 10
