Grit Impregnated Nylon Wheels
Grit impregnated nylon wheels are 22mm diameter on a 2.35mm spindle.
Available in either Aluminium Oxide (whitish) or Silicon Carbide (blue).
Silicon carbide is a sharper grit, making it more aggressive than aluminium oxide.
These wheels are firmer than radial wheels, as a result they work really well for threads and detail areas. The legs are good at reaching down into areas any other abrasive would miss.
Very popular with precision engineers working on aluminium and steel, they will suitably deburr these metals without too much problem.

If you are looking for something bigger, these nylon filament wheels on a 6mm spindle.
These wheels are excellent for fiddly precision engineered parts. The flexible legs are hard wearing but flexible enough to get into quite tricky spots to smooth and deburr. Particularly good on threads and slots.
Impregnated nylon wheels are the right scale for jewellery work. They are pretty aggressive and compared to a lot of jewellery tools they are very firm too. Well suited to more unusual jewellery metals rather than perhaps gold and silver. They are good for pushing into detailed areas, unlike radial discs though they will smooth edges off if used for too long. May be a good option for castings, for getting through the casting skin in tough areas.
