Grinding work of brass metal parts

I use it by wearing it to the dresser's ruther. It is delightful as it is cheaply arranged from coarse to fine ones.
When polishing welding traces of steel, stainless steel, etc.

Due to outstanding cost performance, I purchased quite a number of themselves and used it, but from the latter part of the purchase it surely increased the variation of quality,
Depending on the location, the polishing power of the metal decreases markedly, and the phenomenon that the metal itself burns as it is pressing the rubber has occurred.
However, considering cost performance, I think that it will be so.

I can polish the mold beautifully and it is useful. Cost performance is also reasonable.
For polishing of tool iron parts

It is convenient when you want to polish, but you want to keep the surface in place. We also purchase high cost performance.
Port polishing, parts processing

Although the core shake is few, it was used for aluminum port machining, but even a slight difference in level or the like can easily be torn off and it can not be used.
A typical, cheap and bad one.
I used it to polish aluminum details

I polished a place with fine steps and bumps of aluminum parts.
It is good to polish, but as expected I was wearing quickly and the core appeared halfway through the work.
It seems not to have durability.
