AUTOTOOLHOME 20PCS Abrasive Flap Wheel Sander 80 Grit 1/8" Shank Diameter 32mm 3/8" Thick and 1" Abrasive Sandpaper Flap Sanding Wheel Grinding Head Rotary Tool for Grinding and Polishing

Took on a project to repaint a steel security door with scroll work. The door is at least 20 years old, the wrong color for the house and has some rust. Therefore, I wanted to get as much as possible down to bare metal before applying Rustoluem paint. Had to use a variety of sanding tools to get the job done. Originally started with some sanding bands for my rotary tool (similar to Dremel). As you will find in reviews sanding bands don’t last very long, even shorter life against metal. Therefore, I began my quest to find coarser grit flap wheels with 1/8” shank. With tool spinning at 30K RPM it did a good job of stripping the paint. Yes the paper on the flap wheel will break down. Was able to get 20-30 minutes of use from each wheel. You should make sure to wear safety googles to protect yourself from the debris that flies off.

Like ‘em. They work great.

I have an official Dremel branded 80 grit flap wheel, and it lasted me a really long time. I used it for almost all my small sanding needs, so I got this set to replace it and use it way more often, but I noticed these wear down WAY faster than my original one. Which makes sense due to the much cheaper price. It works similarly to the official one, but expect much more debris flying off at a faster rate, and you'll have to switch these out more often. Other than that, they do the job.

I used these to sand paint of a metal box because the box couldn’t be sandblasted. Sure it took longer but it’s what needed to be done. I only went through about 5 of these and they all worked without falling apart.

I used three bags of these to polish the ports and chambers of some cast iron cylinder heads. The ones that held together were excellent, had a long life, grinding away until there was noting left. They keep cutting all the way down, getting a little smoother cut, but never slicking up and becoming useless like a dremel sanding drum.Unfortunately; a large percentage of them disintegrate within seconds. The quality control is hit or miss, some are great, and work great, some don’t work at all.The shafts were also different sizes and the longer rolls would not fit the standard collet on some of my dremels, too small, couldn’t tighten up on them.I would buy them again, because at least half of them will do a great job, and they are cheap. I wish the quality was consistently good.Do not use them without proper eye protection; when they disintegrate, you will get hit by some high speed sandpaper fragments.
