HSS 1 1/8-16 UN Tap and Die Set, 1-1/8 Inch - 16 Thread Per Inch Unified Constant Pitch Thread, Right Hand High Speed Steel Machine Plug Tap and Round Die for Metalworking, 2-Piece Kit

This 2-piece threading kit provides the essential tools for professional-grade threading tasks involving the 1 1/8-16 UN (Unified Constant Pitch) size. The set consists of a high-speed steel (HSS) machine plug tap and a matching solid round die, both featuring a precision-ground 16 Thread Per Inch pitch. Because these tools are manufactured from industrial-grade HSS, they maintain a sharp cutting edge when working with various metals. The plug tap is optimized for efficient chip removal in through-holes and blind holes, while the round die allows for precise external threading on rods or bolts. This set is a reliable choice for heavy machinery repair, custom engineering projects, and any workshop application requiring specific UN thread standards.

• Precision 1 1/8-16 UN Specifications: Includes one 1 1/8-16 UN machine plug tap and one matching 1 1/8-16 UN round threading die. Engineered for creating or restoring internal and external threads with a consistent 16 Thread Per Inch pitch.
• Industrial High Speed Steel: Manufactured from HSS (High Speed Steel) for balanced hardness and toughness. This material provides the wear resistance necessary for threading carbon steel, alloy steel, cast iron, and aluminum.
• Standard Right Hand Cutting: Both tools feature a right-hand (RH) cutting direction. The plug tap is designed with a lead taper to assist in starting the thread easily, while the round die ensures a smooth, clean finish on cylindrical workpieces.
• Unified Constant Pitch Application: Ideal for specialized machinery repair, automotive maintenance, and industrial fabrication where the 1 1/8" - 16 UN unified thread standard is required for mechanical assembly.
• Clear Technical Markings: Each piece is laser-etched with the 1 1/8-16 UN designation and Thread Per Inch details, allowing for rapid identification and organized storage in a professional machine shop.
