Benchmark Abrasives 4.5" x 7/8" Premium High Density Jumbo Zirconia Type 27 Flap Discs 4 1/2 for Angle Grinder, Sanding Discs, Finishing - Grinding Wheels 4 1/2 inch - (10 Pack) - 40 Grit

These are better than any brand I’ve bought at a store. I’ve probably used every brand available locally to me. Not leaps and bounds better than the best I’ve used but the price makes these supreme.

These are the absolute best flap wheels on the market, tried some lower priced ones and they lasted approximately a 1/4 of the time these do.

I've been using these for years for various steel projects. They're quality flap discs that last quite a while. Given their price, they are substantially better than the name-brand discs you can buy at the big box stores. This is my product of choice.

We have been using this in our shop for several years now. I'm a fabricator and welder for 30 plus years. Needles to say I have used a grinding wheel or two and these are some of the best. We use these in multiple grit and they all perform excellent. Stop wasting your money on expensive welding shop brands.

I use many of the benchmark abrasive products and they never fail..

Good Product. Came in a timely fasion.

these grinding wheels makes my cleanup of slag , weld splatter and and welds job easier thanks.

I’ve been in fabrication for a long time and finding the best consumables for the cheapest price is a constant dance. These are great flap discs and they last a long time compared to others at this price point. I definitely recommend them
