Review on 💎 Diamond Ceramic Porcelain Countertop Tools: Enhanced Cutting Efficiency with Hole Saws & Accessories by Scott Horne

According to my experience, these hole saws are not ideal for industrial and scientific use. While they claim to have diamond ceramic porcelain technology, I found that they dulled quickly and did not hold up well over time. The only pro is that they did initially cut through the porcelain countertop. However, for the price, there are other cutting tools on the market that are more reliable and durable.
