Benchmark Abrasives uses only the highest quality grains and backing material for our flap discs.

The #1 choice for welders and metal fabricators.
Made in accordance with ANSI safety requirements.
For use on an Angle Grinder
Flap discs are used in heavy stock removal, often weld removal. They outperform Resin Fiber Discs due to their increased lifetime and last twice as long as Aluminum Oxide discs. To achieve a finish equivalent to a Resin Fiber Disc, always use a flap disc one grit coarser. e.g. If the operator is running a 60 grit Resin Fiber Disc, try a 40 grit flap disc. This 40 grit flap disc is made with Zirconia Alumina grain, which is ideal for stainless steel and metal applications while still working well with non-ferrous applications. We use a high quality backing plate to help absorb vibration. Specific suited applications include: weld blending, removing weld slag, deburring, edge blending, surface conditioning and general metal fabrication.

Lower Price Flap Disks that work great. I am building a motorcycle trailer and bought many of these flap disks in a variety of grits. They last as long or longer than disks costing much more. Very Good quality, well balanced.
A good quality product , I am well satisfied with this purchase
These are very aggressive. Left neat swirl marks in a wood table top i was prepping for stain. Take the blade guard off your grinder before mounting the disc. Be careful since you can gouge whatever you are sanding. Long lasting too. Good product at a good price
