Threading Die FANAR M28×1.5 — external die for metric threads, M28 x 1.5

FANAR threading die M28×1.5 is an external die designed to cut, form or restore M28 × 1.5 metric threads on rods, shafts and tubular parts. Manufactured for use in repair, maintenance and fabrication, this die provides the correct 1.5 mm pitch and profile for mechanical assemblies and pipe fittings that require M28 × 1.5 external threads. It is suitable for both manual and machine use and is intended for tasks that demand accurate, repeatable thread geometry.

Advantages

The FANAR M28×1.5 die delivers consistent thread profile and pitch accuracy for reliable assembly fit. Its construction allows use in hand die stocks or appropriate threading machines, enabling flexibility between on-site repairs and shop production. The die is compatible with common ferrous and non‑ferrous materials when proper cutting lubricant and technique are applied, helping to extend tool life and maintain thread quality.

Suitable for

• Cutting or restoring M28 × 1.5 external threads on shafts and rods
• Threading tubular parts for pipe fittings and connectors
• Maintenance and repair work in mechanical assemblies
• Small‑batch fabrication requiring metric external threads

Key specifications

• Thread form: metric external thread
• Nominal size: M28
• Pitch: 1.5 mm
• Application: manual and machine threading
• Intended materials: suitable for common ferrous and non‑ferrous metals when using appropriate lubricant

How to use

Secure the workpiece in a vise or appropriate fixture to prevent rotation. Select a proper die holder compatible with the die and ensure correct orientation for right‑hand threads. Apply an appropriate cutting lubricant to the blank and the die teeth. Start threading with the die square to the workpiece, apply steady pressure and rotate the die with intermittent reverse turns to clear chips. For deep threads, advance gradually and periodically back off to remove chips and reduce binding. After threading, clean the thread of swarf and inspect the profile and pitch with gauges or mating parts.

Usage recommendations

Use appropriate cutting oil for the workpiece material, maintain correct alignment and back off periodically to prevent chip buildup. For hardened or abrasive materials, consider pre‑drilling to correct core diameter and use specialized dies or machining methods to avoid premature tool wear.
