Cleveland C54731 Tap Set 1/2-13 Unc Hss 3 Piece

Product Description

The CLEVELAND C54731 is a three-piece tap set designed to cut 1/2-13 UNC internal threads in metalworking applications. The set includes bottoming, plug, and taper chamfer taps, allowing a technician to start, advance, and finish threads in a single workflow without switching tool brands. All three taps are manufactured from high speed steel with a bright finish and feature a 4-flute geometry that provides clean chip evacuation. Overall length is 3.375 inches, thread length is 0.94 inches, and the thread limit is H3, indicating a tolerance suited for standard-fit threaded fasteners in ferrous and non-ferrous materials.

This tap set is used in machine shops, maintenance facilities, and fabrication environments wherever 1/2-13 UNC threads must be tapped by hand or machine. The three-chamfer combination makes it practical for through holes, blind holes, and starting in hard-to-reach locations. It is commonly used by millwrights, machinists, HVAC equipment fabricators, and industrial maintenance technicians who need a complete threading solution for a single thread size. Right-hand thread direction matches standard UNC fastener orientation.
