HSS 1-28 UNS Tap and Die Set, 1 Inch - 28 Thread Per Inch Unified Special Fine Thread, Right Hand High Speed Steel Plug Tap and Round Threading Die for Metalworking and Repair, 2-Piece Kit

This 2-piece threading kit provides the essential tools for professional-grade threading tasks involving the 1-28 UNS (Unified Special) size. The set consists of a high-speed steel (HSS) plug tap and a matching round die, both featuring a precision-ground 28 Thread Per Inch pitch. Whether you are restoring damaged threads on an existing part or cutting new threads from scratch, the HSS construction ensures the tools remain sharp and provide accurate dimensions. The tap is designed for efficient chip removal in through-holes or blind holes, while the die allows for precise external threading on cylindrical stocks. This set is a reliable choice for automotive repair, mechanical engineering, and general workshop applications requiring specific UNS thread standards.

• Precision 1"-28 UNS Threading: Includes one 1-28 UNS machine plug tap and one matching 1-28 UNS round die. Engineered for creating or repairing internal and external threads with a consistent 28 Thread Per Inch pitch.
