Using these tools, our team found that they are incredibly effective at cutting through various materials such as granite and concrete.They are built to last and don`t wear down easily making them ideal for industrial and scientific projects. The diamond-coated blades make for quick, precision cuts that greatly reduce the time spent on a project. The only con we found is that they can be quite loud during use, so hearing protection is a must. Overall, we highly recommend these cutting tools for anyone needing reliable and efficient tools for their industrial and scientific projects..
