  • Extreme Durability and Value Made of hard zirconia alumina material, which lasts longer than standard aluminum oxide abrasive material, built for a more robust and economical grinding wheel
  • T29 Flap Discs with Fiberglass Backing Plate - T29 flap disc features angled flaps, which can be used for edge-working or contoured applications. These discs are also designed with a greater surface area than flat type for stock removal on horizontal surfaces. Fiberglass creates a strong bond with adhesives and does not contaminate the working surface. Fiberglass backing plate can effectively absorb vibration and bring more stable & efficient grinding
  • Great Performance - Each 4.5" x 7/8-Inch arbor size flap disc is compatible with angle grinders operatable of up to 13,000 RPM. Our flap disc set makes it ideal for high-performance blending and stock removal on metals, non-ferrous materials, fiberglass, plastics, wood, and other uneven surfaces

Style: 40 Grit Unit Count: 10.0
Given how inexpensive that 10 of these cost and comparing them for what Lowes wants $6 a piece for, and me being tired of over inflated products. I gave these a try. I admit, I thought they would burn up fast, maybe fall apart on me, or not work as good…NOPE. Threw this on my 4.5-6” Dewalt and made old wood with weathered lines on my deck look new. Posted a pic when I started, that was only about 15 minutes in. To do this whole deck, would have easily took me 1 week to do with an orbital sander. I did the whole deck in 4 hours. Seriously underestimated these. The pads lasted. I only used 3 out of the 10. I only changed the pad because I assumed it took enough abuse.
