Dormer's spiral flute tap is a high precision and durable tool designed to create tapped holes effortlessly. Its construction with powdered metal increases its hardness and resistance against wear while providing accurate threads in materials such as steel, aluminum or brass. With a UNC size of 5/8-11, it ensures compatibility with standard equipment while the four flutes provide efficient chip removal, preventing clogs or damages to components during operation. Moreover, the semi-bottoming design creates uniform threads while reducing chattermarks on the hole walls ensuring quality results even when tapping into hardened materials.
