Norton® Neon® 66623399219 R766 Arbor Thread High Density Coated Abrasive Flap Disc, 6 in Dia, P40 Grit, Extra Coarse Grade, Aluminum Oxide/Zirconia 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.

• Alternating zirconia alumina (blue) and aluminum oxide (black) flaps provides higher performance than aluminum oxide while retaining an economical price
• 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 and operator comfort
• Polyester cotton backing combination for good cut rate and finishing
• High density jumbo flaps discs are the choice when working on uneven or curved surfaces, as well as finer grit blending
• Type 27 flat flap disc with alternating zirconia alumina and aluminum oxide flaps provides higher performance than aluminum oxide while retaining an economical price
• Smooth running, high density/jumbo semi-open flaps improve life, minimize loading on soft metals and make these act like finer grits
• Good choice for coarse grit blending, deburring and stock removal
