Accupro 14065-00T Thread Forming Tap 1/2-13 Unc Plug Tin

Product Description

The ACCUPRO 14065-00T is a thread forming tap designed for producing internal threads in ductile materials without cutting or removing chips. It uses a cold-forming process to displace material, generating a stronger thread form compared to cut threads. Built from powdered metal high-speed steel and coated with titanium nitride (TiN), this tap offers enhanced wear resistance and extended tool life in production and maintenance threading applications. With a plug chamfer and 4-thread lead-in, it is suited for through-hole threading at the 1/2-13 UNC thread size. Machinists, maintenance technicians, and toolroom professionals install this tap in drill presses, CNC machining centers, and hand tapping operations.

This tap is intended for through-hole threading applications in materials such as aluminum, copper, mild steel, and other ductile metals where chip-free thread forming is preferred. The plug chamfer provides a gradual entry over approximately 4 threads, making it appropriate for starting in a pre-drilled hole that passes completely through the workpiece. The right-hand thread direction and Class 3B fit to H5 thread limit make it suitable for precision threading in industrial, manufacturing, and general maintenance environments requiring tight thread tolerances.

Key Features

• Thread forming (chipless) design produces stronger threads by cold-working material rather than cutting
• Titanium nitride (TiN) coating improves surface hardness and reduces friction for longer tool life
• Powdered metal high-speed steel construction provides consistent grain structure and toughness
• Plug chamfer with 4-thread lead-in suits through-hole applications with gradual thread engagement
• H5 thread limit and Class 3B fit meet precision tolerance requirements for close-fitting fastener assemblies
• Single oil groove aids lubrication distribution during the forming process

Compatibility

Designed as an OEM-style replacement or direct-use thread forming tap for through-hole applications requiring a 1/2-13 UNC right-hand thread at Class 3B fit and H5 thread limit.

Installation Notes

Thread forming taps require a specific forming tap drill size — consult a forming tap drill chart for the correct pre-drill diameter, as it differs from standard cut-tap drill sizes. Apply a suitable tapping fluid or cutting oil rated for thread forming before and during the operation. Ensure the workpiece is securely fixtured and the tap is properly aligned to the pre-drilled hole before applying feed pressure. Follow all applicable shop safety practices and machine guarding requirements when operating drill presses or tapping equipment.
