Tough & Sturdy Construction
Three-dimensional grinding discs with overlapping layers of abrasive-coated, fiber-reinforced flaps that fan out from a central hub. As the overlapping layers of the flaps wear away, they continuously expose fresh abrasive mineral for a fast, consistent cut, while the cushioning of the flaps creates a smooth finish.
Under normal conditions, flap discs will generate a finish that is one grade finer than the finish of a fiber disc of the same grade. And, because their overlapping construction allows more abrasive material to be loaded onto the cutting surface, they far outlast typical discs.
By reducing steps and lasting longer, flap discs can greatly improve productivity in grinding operations.

About Flap Disc
Flap discs do double-duty. They can replace bonded wheels and fiber discs because they grind and finish in a single step, making them a time and cost-saving solution in a wide range of applications, particularly where final finish and gouge-resistance are important.Use them for weld grinding, deburring, rust removal, edge grinding, and weld seam blendin.

They complement the use of depressed center grinding wheels, and are the preferred option on light gauge sheet metal or stainless steel where finish is important.
They are manufactured using a high performance Aluminum Oxide making it uselful for all your grinding and polishing needs.
Ideal for: weld grinding, deburring, rust and paint removal, edge grinding, and weld seam blending.

A great deal for great sanding wheels.

I am happy with these grinding/sanding wheels. I needed one for a project I needed and am really pleased with the quality of them. I gave my son some and he was really pleased with them too.

Best Ever

These flap disks are really tough and work great. I am still on the first disk and have sanded down about 50 welds and polished a farm implement for paint. This disk still has a lot of miles on it yet. I would have went through more grinding disks than this. I highly recommend this product.

Long Life

Nice flap discs, especially for the price! So far in my experience, they last as long as the more expensive, better known brands. These actually have aged better than other brands, as they simply wear down toward the middle rather than gradually flying to pieces during use.

Great value

Rebuilding a junkyard axle and these discs make short work of finishing the surface for new paint. Would buy again.

Works well.

Bought this to remove rust from several feet of angle iron that I was repurposing. It was a tight fit in my angle grinder but it worked much better and faster than the original rotary wire brush I first tried and did a much better job. Very pleased.
