Review on Efficient Polishing Solutions with the Oudtinx Multifunctional Polishing Accessories Attachment by Ronnie Polk

The size is not mentioned in the business part. They are pretty small. Their largest diameter is 3/8 to 1/2 inch. Most of them are much smaller than this one. You specify the size by looking at the pictures and determining if it's right for you by comparing the size of the 1/8" shank to the end of the fiber. I used a variable speed Dremel tool with them at about the lowest speed. for polishing guitar frets. They are good for that. I think they are more suitable for jewelry or other small pieces. They're really tough, so keep that in mind when using them as intended. I think slower speed is a must for these!S
