After trying this product I am blown away by the quality and effectiveness of this abrasive brush .It easily tackled rough surfaces and left them smooth and clean. The durable construction ensures a long lifespan, making it a great investment for any industrial and scientific application. The only downside was that it can be a bit too aggressive on softer materials, but that's just part of its strength. Overall, a must-have for any professional working with abrasive brushes in the Abrasive & Finishing Products category..
