HSS 13/16-18 UN Tap and Die Set, High Speed Steel Right Hand Thread Tap and Round Threading Die, 13/16-18 Unified Fine Thread (UN) Metal Threading Tool for Repairing and Re-Threading, 2-Piece Kit

Professional 13/16-18 UN Threading Tool Set Whether you are working on a custom mechanical restoration or routine industrial maintenance, the 13/16-18 UN Tap and Die Set provides the precision required for metalworking tasks. This 2-piece kit is manufactured from industrial-grade High-Speed Steel, offering the necessary toughness to handle both ferrous and non-ferrous metals. The 13/16" diameter and 18 Thread Per Inch configuration follow the Unified Thread Standard, making it essential for specific North American mechanical applications. The tap is designed for hand-threading through-holes or blind holes, while the solid round die allows for consistent external threading on bolts or rods. By using these tools together, you ensure a perfect pitch match and a professional-grade fit for every fastener.

• Precision Threading Specifications: This set includes one 13/16-18 UN right-hand thread tap and one matching round die. Both tools feature a 13/16 inch diameter with 18 Thread Per Inch, ensuring precise compatibility for specialized mechanical projects.
• Industrial Grade HSS Material: Crafted from High-Speed Steel (HSS), these threading tools provide excellent wear resistance and hardness. The HSS construction allows for clean, sharp threads in various materials including carbon steel, alloy steel, and cast iron.
• Versatile Metalworking Applications: Designed for both creating new internal/external threads and repairing damaged existing threads. This set is a reliable choice for automotive maintenance, machinery repair, and custom metal fabrication.
• Efficient Chip Clearance: The tap features straight flutes for downward chip removal, while the round die is engineered with specialized clearance holes to prevent clogging. This design ensures a smooth threading process and prevents tool breakage during operation.
• Standard Fit for Tool Holders: The round die has a standard outside diameter compatible with common die stocks, and the tap features a square shank end for secure fitment in tap wrenches, providing stability and torque during manual threading.
