HSS 1 1/4-24 UNS Tap and Die Set, 1.25 Inch - 24 Thread Per Inch Unified Special Fine Thread, Right Hand High Speed Steel Machine Plug Tap and Round Threading Die, 2-Piece Tool Kit

This 2-piece threading kit provides the essential tools for professional-grade threading tasks involving the 1 1/4-24 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 24 Thread Per Inch pitch. Because these tools are made from industrial-grade HSS, they maintain a sharp cutting edge even when used on tougher metals. The plug tap is optimized for efficient chip removal in through-holes and blind holes, while the solid round die allows for precise external threading on rods or bolts. This set is a reliable choice for automotive restoration, machinery repair, and any engineering project requiring specific UNS thread standards with a 1.25-inch outer diameter.

• Precision 1 1/4-24 UNS Specifications: Includes one 1 1/4-24 UNS machine plug tap and one matching 1 1/4-24 UNS round die. Engineered for creating or restoring internal and external threads with a consistent 24 Thread Per Inch pitch.
• Industrial High Speed Steel Construction: Manufactured from HSS (High Speed Steel) to ensure high hardness and heat resistance. This material allows for clean, accurate threading through carbon steel, alloy steel, cast iron, and aluminum workpieces.
• Standard Right-Hand Threading: Both tools feature a right-hand (RH) cutting direction. The plug tap is designed with a lead taper for easy starting in through-holes, while the round die provides a smooth, burr-free finish on cylindrical rods.
• Specialized UNS Thread Application: Ideal for maintenance, mechanical engineering, and custom fabrication where standard coarse or fine threads do not meet specifications. Specifically designed for high-precision metalworking tasks requiring a 1.25-inch diameter.
• Clear Size Identification: Each piece is laser-etched with the 1 1/4-24 UNS designation and Thread Per Inch details for rapid identification in a professional workshop or machine shop environment.
