Value Collection 84027803 Round Die 8-80 High Speed Steel

Product Description

The VALUE COLLECTION 84027803 is a round threading die designed to cut external threads on rod, bolt stock, and fasteners. Sized for the 8-80 thread specification, this die cuts a right-hand thread and features an adjustable design that allows the machinist to fine-tune thread fit and compensate for wear. The body is manufactured from high-speed steel, which retains hardness at elevated cutting temperatures and extends service life compared to carbon steel tooling. Machinists, toolmakers, and maintenance mechanics use this die for threading operations on bench lathes, drill presses with die holders, or standard die stocks.

This die is suited for threading applications requiring the 8-80 Unified National Extra Fine thread form. The 8-80 designation indicates a No. 8 screw diameter with 80 threads per inch, a fine-pitch specification common in precision instruments, optical equipment, and small mechanical assemblies. The adjustable feature accommodates both roughing and finishing passes in a single tool, making it practical for low-volume threading in machine shops, maintenance environments, and tool rooms.

Key Features

• 8-80 thread size for No. 8 diameter, 80 threads per inch cutting
• High-speed steel construction retains cutting hardness under heat
• Adjustable design allows thread fit tuning and compensates for tool wear
• Right-hand thread cutting for standard fastener applications
• Round die form compatible with standard die stocks and holders

Compatibility

Designed as an OEM-style replacement and standard-production round die for use in conventional die stocks and die holders accepting round dies in the appropriate outer diameter for 8-80 thread cutting.

Installation Notes

Round dies are installed and secured in a matching die stock using the set screws provided on the stock. Ensure the die is seated squarely in the holder before beginning the threading operation. Use appropriate cutting fluid for the workpiece material to extend die life and improve thread finish. Inspect the workpiece diameter against published thread data for the 8-80 specification before cutting to avoid overloading the die.
