Value Collection 315-1129 Round Die 1/4-80 1 in Od Hss

Product Description

The VALUE COLLECTION 315-1129 is a round threading die used to cut external threads on fasteners, bolts, rods, and other cylindrical workpieces. Sized for a 1/4-80 thread specification with a 1 inch outside diameter, this die fits standard round die stocks and holders commonly found in machine shops, maintenance facilities, and trade toolboxes. Manufactured from high-speed steel (HSS), it maintains cutting edge hardness under the heat generated during threading operations. The adjustable design allows the operator to fine-tune thread fit and take incremental cuts, which is especially useful when threading softer or harder materials. Machinists, pipefitters, and maintenance technicians install and use this die for custom fabrication and repair work.

This die is suited for threading mild steel, aluminum, brass, and similar materials where a 1/4-80 Unified National Special (UNS) right-hand thread form is required. The 1/4-80 designation indicates a 1/4 inch nominal thread diameter with 80 threads per inch, a fine-pitch specification common in instrument work, optical equipment, and precision mechanical assemblies. At 0.5 pounds, the die is compact and easy to handle in bench or field conditions.

Key Features

• 1/4-80 UNS thread form with 80 threads per inch fine-pitch profile
• 1 inch outside diameter fits standard round die stocks and holders
• High-speed steel construction resists heat buildup during cutting
• Adjustable design allows thread fit tuning and incremental depth control
• Right-hand thread direction for standard fastener applications

Compatibility

Designed as an OEM-style replacement or direct-use round die compatible with standard 1 inch round die stocks and holders used in manual threading operations.

Installation Notes

Secure the die firmly in a properly sized round die stock before use. Apply cutting oil liberally to the workpiece and die during threading to extend tool life and improve thread quality. Reverse the die periodically to break chips and prevent binding. This tool should be used by machinists or skilled tradespeople familiar with hand threading procedures and appropriate workholding practices.
