The Dormer Straight Flute Taper Lead Hand Tap is a UNC-threaded tool manufactured to ISO standards, designed for versatile use in hand or machine tapping of medium-strength, medium carbon, and alloy steels. It features a taper lead chamfer that produces thin chips, enabling a gradual and smooth cutting action. This tap is considered the best choice for producing short through holes up to 1.5 times the diameter (1.5xD).
