Review on 💎 Z LION Diamond Granite Grinding and Sanding Tools by Allan Segal

The Z LION diamond router bit for granite did not live up to its claims. As a result of my tests, I determined that this product is not suitable for industrial and scientific use. The bit struggled to maintain a steady cut and left jagged edges on the granite. The only pro is that it arrived quickly. However, the cons outweigh this as the bit is not worth investing in for serious jobs.
