Cle-line C65761 Round Die 1/4-28 Unf Hss Adjustable

Product Description

The CLE-LINE C65761 is a round threading die designed to cut external threads on bolts, studs, and round stock. It cuts a 1/4-28 UNF right-hand thread profile in a single pass and is adjustable to fine-tune thread fit and extend service life. Manufactured from high-speed steel, the die maintains cutting edge hardness through the heat generated in production threading work. At 1/4 inch thick, it seats in standard round die stocks of the appropriate size. This die is a standard tool for machinists, maintenance technicians, and trade professionals who need to chase damaged threads or cut new external threads on fastener stock.

The C65761 is suited for threading mild steel, aluminum, brass, and similar machinable materials commonly encountered in mechanical maintenance, plumbing rough-in work, and general fabrication. The 1/4-28 UNF specification makes it appropriate for precision fastener applications where a fine thread pitch is required, such as instrument fittings, hydraulic adapters, and small mechanical assemblies. The adjustable design allows the operator to open or close the die slightly to achieve a snug or free-running fit on the finished thread.

Key Features

• 1/4-28 UNF right-hand thread profile for precision fine-thread applications
• High-speed steel construction resists heat buildup during cutting for extended die life
• Adjustable design allows thread fit calibration without changing tooling
• 1/4 inch thickness fits standard round die stocks sized for this series
• Series 0710 designation for straightforward replacement and reorder identification

Compatibility

Designed as an OEM-style replacement round die for use in standard round die stocks sized to accept Series 0710 round dies of the appropriate outside diameter.

Installation Notes

Round dies are installed and secured in a matching die stock using the stock's set screws before use. Ensure the die is seated squarely in the stock before beginning a threading pass. Apply cutting oil to the workpiece and die during threading to reduce heat and improve thread finish. Inspect the die and workpiece for proper alignment before applying torque to avoid cross-threading or die damage.
