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.

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.

The 1/8 handles on the 10pk I got were only 1-1/16 to 1-1/8 in length rather than 1-1/4 if that matters. The heads were 3/8 thick and 1-3/16 in diameter though. They fit on my rotary tools just fine. They were similar quality to flap wheels I have had in the past. They come fairly hard, so do note in the product description under tips where they recommend soaking before use. The bottom of the flap wheels is labeled with the rotational speed but is not labeled as 120 grit so I would label them with a marker before use or storing so you will know for future reference. 120 grit is pretty aggressive, so it would be good to do more final shaping on little intarsia wood pieces as well as working on cleaning up rust off metal pieces and such.

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

Works perfectly for my small projects!

These were just the right size to use on my water pump. I wanted to clean inside the ports. I am used to flap wheels will a larger shank (1/4) but these smaller 1/8 shank worked fine. Will need to get some with a coarser grit for other projects. Would buy these again. Thumbs up.

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

When mounted in my Dremel rotary tool and run at maximum rotational speed, one of these flap wheels did a good job in… | • … removing a patch of rust from a badly rusted piece of steel (photo 1). | • … removing the OD burr from an abrasive-wheel-cut piece of conduit (photos 2A and 2B). The wheel ran smoothly, and I detected no obvious rotational imbalance, neither at the beginning of my tests nor at the end. I can see that these wheels will be a handy addition to my rotary-tool assortment. At this point I find no fault with this product and therefore give it a full five-star rating.
