This hole saw has exceeded my expectations .Thanks to my knowledge gained in practice, i know A solid performer when I see one. It cuts through wood, plastic, and metal with ease, leaving precise and clean cuts. The hardened steel construction ensures durability and a long lifespan. The only downside is that it can sometimes be difficult to remove the cut-out piece from the saw but a quick tap on the base usually does the trick. Overall, a great addition to any tool collection..
