Norton 63642503527 4-1/2x5/8 - 11 in. Charger Coated Flap Discs, P40 Grit, 5 pack

• Zirconia alumina abrasive for aggressive cut and long life with 2X-3X total performance over aluminum oxide products; excellent choice for mild carbon steel and welds
• 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
• Cotton back cloth for good finish and fast initial rate of cut
• 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 5
