As someone who is new to the Abrasive & Finishing Products category, I was hesitant to purchase a grinding tool with coarse grit .However, after using this product, our team found that it was extremely effective in providing a smooth and polished finish on our material. The tool is durable and can be used for various tasks. The only downside is that it can be a bit difficult to handle for beginners. Overall, I highly recommend this product for anyone in need of a reliable and efficient finishing tool for industrial and scientific use..
