Value Collection 314-1955 Round Die M40x1.5 3 Inch Od

Product Description

The VALUE COLLECTION 314-1955 is a round threading die designed to cut external metric fine threads on cylindrical workpieces. Sized at M40x1.5, it produces a 40 mm nominal diameter thread with a 1.5 mm pitch. The die body measures 3 inches in outside diameter and is machined from high-speed steel for durability under repeated use. It is adjustable, allowing minor diameter compensation to fine-tune thread fit. Right-hand thread direction is standard. Machinists, toolmakers, and maintenance technicians use this die in die stocks or threading fixtures for shop and field threading operations.

This die is suited for metric fine threading applications in manufacturing, repair, and maintenance environments. The M40x1.5 thread form is commonly required on hydraulic fittings, spindles, precision shafts, and mechanical assemblies where a finer pitch than standard metric is specified. The 3-inch OD fits corresponding die stocks designed for that body size. The adjustable design allows the cutting diameter to be opened or closed slightly, giving the operator control over thread class and fit without changing tooling.

Key Features

• M40x1.5 metric fine thread form for precise pitch control on larger-diameter workpieces
• 3-inch outside diameter body fits standard die stocks sized for 3-inch dies
• High-speed steel construction resists heat and wear through repeated threading cycles
• Adjustable design allows fine-tuning of thread diameter for fit class control
• Right-hand thread direction — standard for the vast majority of threading applications

Compatibility

Designed for use in die stocks or threading frames that accept a 3-inch outside diameter round die. Suitable for cutting M40x1.5 metric fine external threads on steel, aluminum, brass, and similar machinable materials.

Installation Notes

This die is installed and secured in a matching die stock using the stock's set screws before use. Secure the workpiece in a vise or fixture to prevent rotation during threading. Apply appropriate cutting fluid to the workpiece and die to reduce heat and extend tool life. Inspect the die for chips or wear before each use, as a damaged cutting edge will produce out-of-tolerance threads.
