I often use it for chamfering the end face of stainless steel, brass, iron material.

I think that it is good because it can be used up until the end when the eyes or less usability is good and the abrasive disappears. Also, it is still better if the price is a little cheaper. I do not use it every day at work, I use it occasionally, so I think that it can not be helped even if the price is high.
