Rocaris 10 Pack Flap Wheel, 120 Grit for Rotary Tools，1/8 inch Shank (32X10X3)

Will quickly remove rust and polish and deburr metal. They also work chucked into a drill, though slower. These are very abrasive, function more like coarse grit than 120. Would not use for fine sanding of wood, they will leave scratches. I cleaned, polished, and sharpened a rusty pair of long handled pruning shears. The flap sander worked great and only took a few minutes for the whole cleanup. Follow the instructions and soak the disc first, otherwise they are too stiff. Be sure to wear safety glasses, the dust and sparks fly everywhere sometimes right at you.

DESCRIPTION: This is a set of ten abrasive flap wheels, intended for use in hand-held motor tools such as a Dremel brand. The dimensions are 32mm (overall diameter) x 10mm (width of individual flaps) x 3mm (shaft diameter). --------------- POTENTIAL USAGE: I used this product as intended, in a hand-held Dremel tool. It worked as expected on wood and metal surfaces. As with any powered abrasive tool, it sheds a lot of specks of abrasive, so proper personal protection is essential for safety. I generally work under a plastic shield, but I removed the shield for the staged photo. The 1/8 (3mm) shaft also fits in a stationary drill press for constant medium-speed use. This worked well for smoothing edges of wood pieces. The shaft also fits in a portable cordless screwdriver for slow or variable-speed use, and would work well for irregular surfaces such as automotive panels, deburring pipes, or in locations without AC power. Since these tools are reversible, it is important to be sure the flap wheel is turning in the correct direction (as if you were tightening a screw). --------------- MY USAGE: I primarily use these for polishing and brightening the wheels of model train locomotives. These wheels must be kept spotless as they provide the electrical connection to the locomotive. While holding the locomotive in a cradle (see photo) I could easily address the wheel surfaces using a light touch. I had previously used a little wire brush wheel for this purpose, but that was a bit too aggressive for this use. --------------- Note the online listing for this product specifies 120 grit in the description, but 80 grit in the illustration; so not sure which is correct.

Using my rotary tool, I gave it a test on some scrap wood (see photo) and it bit right in. I was able to cut a groove in seconds. So, it seems to me to be a bit more aggressive than 120 grit. I took off a star for this apparent inconsistency. Otherwise, these are a great addition to my rotary set. Better yet, Im throwing a few in my drill bag because I see them being helpful when I do something like deck building. There always seems to be a time you need to take off a little of a bad cut or find a way to get around a proud obstruction. These should do well for that purpose. I did not try it on metal. I see no reason that it wouldnt also take off rust as advertised because these have some serious bite to them.

Im using these sander heads with my Dremel tool for 3D print finishing mostly. Theyre decent quality and last longer than I would have initially expected. For the price, Theyre a decent value, too. No complaints at all. Highly recommended.

Nice sanding wheels for guitar making. There are many curves that are easier to manage using these. Perfect for small projects and strong.

Working on a project with live edges and needed flap type disks. Fits perfectly in my rotary tool and allowed me to sand down the live edge without losing its natural beauty. A flat sanding disk wouldn’t have been able to handle the contour surfaces without removing excessive material. Overall excellent product and great addition to my rotary tool set.

The flapwheels are not marked and the grit is more like 60 and not 120. It damaged my work surface.

I use these to knock rust off automotive parts. These will fit the bill.
