  • 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

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

  • extremely powerful and does not fall apart
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. But I inspected each one after I swapped it out for a new one, and it for sure had way more life, so I saved those for whatever. But yes, they are worth the money 100%. Do not waste your money at Lowes or Depot. T ... show more

  • Great flap disc for wood carving...
Style: Multi Grit Unit Count: 10.0
Great flap discs. Excellent quality. I use then to debark walking stiks and create unique patterns in the walking stick shaft. Easy to control. The 40 grit disc removes wood quickly, while higher grit discs help with the finishing touch.
