After I put this hole saw to the test, I am thoroughly impressed with its cutting power and efficiency .The bi-metal construction makes for a durable and long-lasting tool able to handle tough materials with ease. The saw creates clean and precise cuts, leaving minimal debris and reducing the need for additional cleanup. The only downside is its slightly higher price point compared to other hole saws on the market. Overall, an excellent choice for those in need of a reliable and efficient cutting tool..
