Other than flap and power tools used in metal finishing, another option that is readily available on the market is a nylon scotch brite wheel. It is effective in making metals shiny and deburring the surface to keep them as smooth as possible.
Like most other products, though, the wide variety of options can be overwhelming, especially considering the numerous materials used in polishing wheels. But what you need to know is this: the most important aspect of a reliable scotch brite wheel is having a user-friendly assembly and being made with premium quality material.
Take this scotch brite wheel attachment for example. It features thick layers of scouring pads with sandpaper inserted between wedges, both effectively working together to polish metal, remove bumps, and give metals a shiny finish.
This scotch brite wheel is specifically made for drilling tools, meaning you can attach the wheel to your portable drill to easily use it for your metalworking projects. It has good heat dissipation, operates with little to no noise, and has a long service life.
The striking red color also allows you to check the material easily, especially if you think it is starting to show signs of wear. This is better than using scouring pads in darker colors where you have a hard time looking for problems on the material. The bright color contrasts with the color of common small debris that may stick onto the pad and potentially damage the surface you are trying to polish.
To get the best results, we recommend applying a polishing compound to the wheel as it revolves. Make sure to gradually increase the amount of the compound applied on the scouring pads instead of pouring everything in one go. Once you have applied enough polishing compound on the buffing pads, use slight pressure in the revolving polisher to smoothen the surface.
