Cle-line C65751 Round Die 12-24 Unc High Speed Steel

Product Description

The CLE-LINE C65751 is a round threading die designed to cut 12-24 UNC external threads on bolts, studs, and cylindrical stock. Made from high-speed steel, it holds cutting edge hardness at elevated temperatures, making it suitable for production and repair threading work. The die features an adjustable design that allows minor diameter tuning to achieve a closer or looser thread fit. At 0.25 inches thick, it fits standard round die stocks sized for this die series. Licensed machinists, tool-and-die workers, and maintenance mechanics are the primary users of this type of tooling.

This die is suited for threading mild steel, aluminum, brass, and similar machinable materials in both shop and field applications. The 12-24 UNC thread form is common in machine screws, chassis fasteners, and light structural assemblies across HVAC, electrical enclosure, and general mechanical fabrication work. It is used in both manual die stocks and benchtop threading setups. The right-hand thread direction follows standard fastener convention for the majority of threading tasks.

Key Features

• High-speed steel construction retains hardness under heat generated during threading
• Adjustable die allows fine-tuning of thread fit from standard to slightly loose or tight
• Right-hand thread direction matches standard UNC fastener convention
• 12-24 UNC thread size suits common machine screw and light-assembly applications
• 0.25 inch thickness fits standard round die stocks for Series 0710

Compatibility

Designed for use in round die stocks that accept Series 0710 dies. Cuts 12-24 UNC external threads on compatible cylindrical workpieces.

Installation Notes

This die is installed and operated by machinists or mechanics using a matching round die stock. Secure the workpiece firmly before threading and apply cutting oil to extend die life and improve thread quality. Inspect the die for chipping or wear before each use. Follow standard shop safety practices when operating threading tooling.
