Review on Efficient Concrete Masonry Cutters: Connecting Center Cutting Tools for Precise Cuts by Tom Gourgues

Based on my experience, these hole saws were a complete letdown. Despite being labeled as "Industrial and Scientific," the quality was far from satisfactory. The pros were that they were compatible with a variety of cutting tools. However, the cons were numerous. They dulled quickly, struggled to make clean cuts, and were prone to breaking. Overall, if you're looking for reliable cutting tools, steer clear of this brand.
