It was planned to be used in the Shinano air disk grinder, but it hit the disc cover and it could not be used. I wish it had been better if the outer diameter was a little smaller. Compared to Kore, Bevel Black has a small outer diameter, so it can be used normally without the interference of the disc cover. From now on I will make it bevel black.
As a substitute for bevel black, I bought it for testing. Because it is a Japanese manufacturer, it will be okay. According to the person at the scene, when using this product, black marks remain. And, the adhesive has protruded to the middle, it can not be used until the end. It was a strange evaluation. It was that the monotalou made in China is still better. It was an article that I thought would be made in Japan. Because I compare it with bevel black, I think that it is a crime.
