Value Collection 82238035 Round Die M3x0.5 1 in Od Lh Hss

Product Description

The VALUE COLLECTION 82238035 is a round threading die used to cut external metric left-hand threads on bolts, studs, and round stock. Manufactured from high-speed steel (HSS), this die holds cutting edge hardness under the heat generated during threading operations. It measures 1 inch in outside diameter and 0.25 inches thick, sized to fit standard 1-inch die stocks. The M3x0.5 designation indicates a 3 mm nominal thread diameter with a 0.5 mm pitch per the metric coarse thread standard. An adjustable split design allows the technician to fine-tune thread fit by opening or closing the die slightly with the die stock set screws.

This die is used in machine shops, maintenance facilities, and field service applications wherever metric left-hand threads must be cut or restored. Left-hand thread cutting dies are typically specified for applications where a standard right-hand thread would loosen under rotational load, such as certain spindles, turnbuckles, and specialty fastener assemblies. Machinists, tool-and-die workers, and maintenance technicians use this die when chasing damaged M3 left-hand threads or cutting new ones in mild steel, aluminum, brass, and similar machinable materials.

Key Features

• M3x0.5 metric coarse thread profile for 3 mm nominal diameter applications
• Left-hand thread direction for counter-rotation fastener requirements
• High-speed steel construction maintains hardness and edge retention through repeated use
• Adjustable split design allows thread fit fine-tuning via die stock set screws
• 1 inch OD fits standard 1-inch round die stocks and holders
• 0.25 inch thickness suits shallow die stock recesses common on compact holders

Compatibility

Designed to seat in any standard 1-inch round die stock or die holder that accepts a 1 inch OD by 0.25 inch thick round adjustable die.

Installation Notes

Secure the die in a properly sized die stock before use and confirm the set screws engage the die adjustment slots. Apply cutting oil liberally to the workpiece and die before and during threading to reduce heat and improve thread finish. Advance the die in short increments, backing off periodically to break chips, especially in blind or deep threading applications. Inspect the die cutting edges before each use and replace if chipping or dulling is observed.
