According to my experience this hole saw is a game changer. It was everything I was looking for in a cutting TOOL... The quality and performance of this saw are top-notch. The carbide material made this saw durable and ideal for its industrial and scientific purposes. The precision and speed it offers made my work less laborious and tedious. The only downside is that it is expensive compared to other hole saws. But the cost is worth the investment, especially in the long run because of its durability..
