ISO Metric Internal Threading Inserts – Full Profile
These ISO metric internal threading inserts are designed for precision internal thread turning on CNC and conventional lathes.
The current range covers metric pitches from 0.5 mm to 6.0 mm using Z16IR and Z22IR insert platforms.
The full-profile geometry is designed to produce the complete ISO metric thread form when the insert pitch is correctly matched to the required thread.

Insert Size Selection
- Z16IR – metric pitches from 0.5 mm to 3.0 mm
- Z22IR – metric pitches from 3.5 mm to 6.0 mm
Select the insert platform based on the required thread pitch and compatible internal threading bar.
Typical Applications
- Internal ISO metric threading
- CNC lathe threading
- Conventional lathe threading
- General engineering
- Production machining
- Maintenance and repair machining
How to Select the Correct Insert
- Confirm the required ISO metric thread pitch.
- Select the matching full-profile insert.
- Confirm whether a 16IR or 22IR insert platform is required.
- Check compatibility with the internal threading bar.
- Confirm adequate bore diameter and tool clearance before machining.
For full-profile threading inserts, the insert pitch should match the required finished thread pitch.
Compatible Tooling
Use these inserts with compatible internal threading bars designed for the corresponding IR insert platform.
