Threading Insert FANAR 16ER2.5ISOBMA for External Threading ISO 2.5, Right-hand

FANAR 16ER2.5ISOBMA is a turning threading insert engineered for external ISO metric threads with a 2.5 mm pitch. Designed for use in carbide holders on lathes, the insert creates accurate ISO thread profiles on shafts and cylindrical components. Its indexable design allows fast replacement in production and repair environments while supporting right-hand threading operations.

Advantages

The insert delivers consistent thread geometry and repeatable results when machining external ISO metric threads at a 2.5 mm pitch. Its indexable format reduces downtime by allowing quick swaps without regrinding, and compatibility with standard carbide holders ensures secure clamping and dimensional stability. The design supports efficient chip flow and helps maintain surface finish and dimensional accuracy during turning operations.

Suitable for

• External ISO metric thread turning on lathes
• Production runs and repair work on shafts and cylindrical parts
• Right-hand threading applications
• Use in carbide indexable tool holders for quick replacement

Key specifications

• Thread standard: ISO metric external thread
• Thread pitch: 2.5 mm
• Hand: right-hand threading
• Insert type: indexable turning/threading insert
• Intended mounting: carbide holder for external threading

How to use

Install the insert into a compatible carbide threading holder and secure according to the holder manufacturer's torque specifications. Set the lathe to the correct spindle speed and feed corresponding to the 2.5 mm pitch and material being machined. Use appropriate cutting speeds, feeds, and coolant for the workpiece material to achieve the desired surface finish and dimensional accuracy. Index the insert when wear is detected to restore cutting geometry.

Usage recommendations

Match cutting parameters (speed, feed, depth of cut) to the workpiece material and tooling system; use coolant or flood lubrication for improved chip evacuation and tool life when machining steels and alloys. Verify holder compatibility before use and perform regular inspections to replace the insert at the first signs of wear or chipping to maintain thread quality.
