Norton® Blaze® 66261097678 R980P Center Mount High Density Coated Abrasive Flap Disc, 4-1/2 in dia, 7/8 in Center Hole, 36 Grit, Extra Coarse Grade, Ceramic Alumina Abrasive, Type 27 Flat Disc

Flap discs are versatile grinding and finishing tools with three main components - backing plate, adhesive, and abrasive flaps. The flaps wear during use continually exposing new abrasive grain. The different variations of the components provide a variety of applications, ranging from heavy stock removal to blending to finishing. Flap discs are designed for portable grinder applications and can combine the 2-step stock removal and finishing operations of depressed center wheels and fiber discs into one operation.

• Latest generation ceramic alumina grain with a unique grinding aid that provides 2 to 3 times performance over zirconia alumina on stainless, alloys and other hard to grind materials
• Type 27 flat discs are designed to be used at a 0 to 15 deg angle on flat surfaces for blending and smooth finishing
• Fiberglass resin backing plates are the most popular due to high strength, lightweight and ability to absorb vibration
• Y-weight polyester flaps significantly improve life, grain retention and fray-resistance
• High density jumbo flaps discs are the choice when working on uneven or curved surfaces, as well as finer grit blending
