Review on High Performance SEL1212H16 SER1212H16 Carbide Threading Tool for Superior Turning Results by Steve Hauck

This tool set for cutting left and right-hand threads with a 12 mm shank is absolutely clean! The surface underneath and around the insert is just very smooth. The earbuds are tight and I cannot describe how HAPPY I am! Holding them in your hands will give you pleasure. It's worth every penny!
