According to my experience, these uncoated cutting tools have significantly improved my industrial milling operations. The overall diameter ensures accuracy and precision in cutting, while the sturdy build ensures longevity. As compared to other coated cutting tools, these are more economical and do not require frequent replacement. However, their uncoated nature may cause them to wear out faster than coated options when used excessively on harder materials .Overall, a great investment for any industrial and scientific milling needs..
