This disc that I use on a wheel from the same company offers satisfactory performance, especially considering its price. It is definitely sufficient for simple tasks and general use, although it does not provide exceptional results and durability for continuous use. For anyone looking for something more professional and demanding, they will need to invest in something more expensive. However, for basic needs and everyday jobs, I believe it is an ideal choice that meets expectations for its price.

It can't even cut nails, let alone iron. Overall, a terrible product, which is why it has a corresponding price.

I bought 4-cornered 0.5mm 70-pack, at first it cut quite well but then it left the nail intact, it didn't progress at all... I won't buy it again

No problem, they are excellent and of course they don't break like others. Just be careful because they are 1.2mm and not 1mm, but for their price they are the best

The product in the photo, as shown, states: "max 13,300 RPM," while in reality, the one you will receive has: "max 4,400 RPM." Therefore, the information provided is false. The coating is of poor quality, and the edges break as soon as you touch it. That's all for now. Once I use it, I will provide more information.
