This carbide square is a perfect addition to my tools for milling. it cuts through metal smoothly and its durability is impressive. As my tests showed, it holds up well even after multiple uses. The design is great for precision and accuracy making my work even easier. The only downside is that it's a bit pricier than some other options, but the quality more than justifies the COST. Overall, a great investment for anyone in the industrial and scientific field..
