Cle-line C65805 Round Die 1/4-28 Unf 1 in Od Hss Adjustable

Product Description

The CLE-LINE C65805 is a round threading die designed to cut external threads on bolts, studs, and rod stock. It produces a 1/4-28 UNF right-hand thread profile and is manufactured from high-speed steel for durability under continuous cutting loads. The 1 inch outside diameter fits standard die stocks and holders sized for that OD. At 3/8 inch thickness, the die provides adequate thread engagement depth for clean, accurate cuts. An adjustable design lets the technician fine-tune cutting tolerance to achieve the desired thread fit. This die is used by machinists, pipefitters, maintenance mechanics, and industrial tradespeople who need to chase, repair, or create new external threads in the field or shop.

The C65805 suits applications requiring fine-pitch external threading on 1/4 inch diameter fasteners and threaded rod. The 1/4-28 UNF specification is common in precision assemblies, automotive components, instrumentation, and light mechanical hardware where a finer thread pitch is preferred over standard UNC for added holding strength in thinner materials. The adjustable feature is particularly useful when cutting threads in harder alloys where a progressive pass approach reduces tool stress and improves thread quality.

Key Features

• 1/4-28 UNF thread standard for fine-pitch external threading
• High-speed steel construction provides resistance to heat and wear during cutting
• 1 inch outside diameter fits standard die stocks rated for that OD
• 3/8 inch thickness delivers solid thread engagement depth
• Adjustable design allows fine-tuning of thread fit and cutting tolerance
• Right-hand thread direction matches the most common fastener orientation

Compatibility

Designed as an OEM-style replacement or shop-standard round die for use in 1 inch OD die stocks and threading sets that accept Series 0710 round dies.

Installation Notes

Round dies are installed and operated by machinists or mechanical tradespeople using a matching die stock or die holder. Secure the die firmly in the holder before use and apply cutting oil generously to the workpiece to reduce friction and extend die life. Advance the die in short increments, reversing periodically to clear chips and prevent thread tearing. Inspect the die for cracks or dull cutting edges before each use and replace if damaged.
