Cle-line C65901 Round Die M20x2.5 Hss Adjustable

Product Description

The CLE-LINE C65901 is a round threading die designed to cut external metric coarse threads on bolts, studs, and round stock. Made from high-speed steel, it handles the heat and wear demands of production and repair threading work. The M20x2.5 designation means it cuts a 20 mm nominal diameter thread with a 2.5 mm pitch. At 0.5 inches thick, it seats securely in a standard die stock. The adjustable design allows the user to fine-tune thread fit by slightly opening or closing the die split. Right-hand thread direction is the standard for most metric fastener applications. Machinists, maintenance technicians, and tool and die workers are the primary users.

This die is suited for threading mild steel, stainless, aluminum, brass, and similar machinable materials in shop, field, or maintenance environments. It belongs to the CLE-LINE Series 0710M family of metric round dies. Typical applications include chasing damaged threads, threading new rod stock, and fabricating custom fasteners. It fits die stocks sized for the standard round die outer diameter used with M20 tooling. The adjustable split allows fine control over thread class of fit.

Key Features

• M20x2.5 metric coarse thread profile for standard metric fastener sizes
• High-speed steel construction resists heat buildup and wear during threading
• Adjustable split design allows thread fit fine-tuning without replacing the die
• Right-hand thread direction matches the vast majority of metric fastener applications
• 0.5 inch thickness fits standard round die stocks sized for M20 tooling
• Series 0710M designation for straightforward replacement and reorder

Compatibility

Designed as an OEM-style replacement or direct-use round die for standard die stocks that accept M20 metric coarse round dies; consult your die stock specifications to confirm outer diameter fitment before use.

Installation Notes

Installation is performed by a machinist or qualified maintenance technician using a properly sized die stock handle. Secure the die in the stock using the set screws before beginning any threading operation, and apply cutting fluid to reduce heat and extend die life. Inspect the workpiece diameter before threading to ensure it matches the M20 nominal size. Adjustments to thread fit should be made in small increments using the die stock adjustment screws against the die split.
