Value Collection 82236161 Round Die M39x3 3 Inch Hss

Product Description

The VALUE COLLECTION 82236161 is a round threading die designed to cut external M39x3 metric fine threads on rod, bolt stock, and cylindrical workpieces. Manufactured from high-speed steel (HSS), it delivers the hardness and heat resistance required for threading mild steel, stainless, aluminum, and similar materials in production or repair environments. The die measures 3 inches in outside diameter and is adjustable, allowing the operator to set cutting depth and compensate for wear. It cuts right-hand threads and conforms to the metric fine thread standard. Machinists, tool-and-die technicians, and maintenance tradespeople are the primary users.

This die is suited for shop floor and field applications where large-diameter metric fine threads must be cut or re-chased on fasteners, studs, and threaded assemblies. The M39x3 designation is commonly encountered in heavy industrial and structural fastener work. The 3-inch OD fits standard round die stocks and holders sized for that diameter. Adjustability makes it practical for both roughing and finishing passes in a single tool.

Key Features

• M39x3 metric fine thread specification for large-diameter external thread cutting
• High-speed steel construction resists heat buildup during extended cutting operations
• 3-inch outside diameter fits standard round die stocks designed for that size
• Adjustable die allows fine-tuning of thread depth and compensation for tool wear
• Right-hand thread direction for standard fastener applications
• Metric fine thread standard for precision-fit threaded assemblies

Compatibility

Designed as an OEM-style replacement and general-use round die for any die stock or holder that accepts a 3-inch outside diameter round die.

Installation Notes

Round threading dies are installed and operated by machinists and qualified maintenance technicians. Secure the die firmly in a properly sized die stock before use and verify the adjustable screw is set for the desired thread fit before beginning a cut. Apply cutting oil generously throughout the threading operation to extend tool life and improve thread finish. Inspect the workpiece diameter against the nominal M39 major diameter specification before cutting to ensure proper thread form.
