This carbide hole saw is an excellent addition to any industrial and scientific cutting tool collection .As my tests showed, it easily cuts through a wide range of materials with precision and efficiency. The teeth are sharp and durable, and the overall construction is robust. The only downside is that it`s a BIT on the pricier end compared to some other hole saws on the market. However, the quality more than justifies the cost. Overall i highly recommend this tool for any professional cutting needs..
