60° ISO Metric Threading Inserts are precision carbide threading inserts designed for machining standard ISO metric threads with a 60° thread angle. They are available for both external and internal thread turning and can be supplied in partial-profile and full-profile geometries for different threading applications.
Manufactured from high-quality tungsten carbide substrates and available with PVD coatings, these CNC threading inserts provide stable cutting performance, good wear resistance, and consistent thread profile accuracy. Common insert configurations include 16ER, 16IR, 22ER and 22IR, with different metric pitches available according to machining requirements.

60° ISO Metric Threading Inserts are commonly used for producing standard metric threads on shafts, tubes, fittings, fasteners and other precision-machined components.
Typical applications include:
Metric threading inserts are available for a wide range of ISO metric pitches, including fine and coarse threads. Typical options include:
0.5 mm, 0.75 mm, 1.0 mm, 1.25 mm, 1.5 mm, 1.75 mm, 2.0 mm, 2.5 mm, 3.0 mm and larger pitches.
The correct insert should be selected according to the required thread pitch, external/internal application, insert geometry and workpiece material. Commercial ISO metric threading systems commonly distinguish ER inserts for external threading and IR inserts for internal threading.
| Type | Main Advantage | Typical Application |
|---|---|---|
| Partial Profile | One insert can cover a range of pitches | General-purpose metric threading |
| Full Profile | Forms the complete crest and root profile | High-accuracy thread production |
| External ER | Designed for external threads | Shafts, studs, external diameters |
| Internal IR | Designed for internal threads | Holes, bores and internal threads |
Full-profile inserts are designed around a specific pitch and can generate the complete thread profile, while partial-profile inserts are more flexible when machining different pitches.
Typical designations include:
The actual available sizes, pitches, grades and geometries can be customized according to your tooling system and application.
Depending on the carbide grade and coating, 60° ISO Metric Threading Inserts can be used for machining:
Steel | Stainless Steel | Cast Iron | Alloy Steel | Non-Ferrous Metals | Hardened Materials
Different carbide grades and PVD coatings can be selected to balance wear resistance, edge toughness and cutting performance for specific workpiece materials.
We provide OEM and customized carbide threading inserts for distributors, tooling companies and CNC machining manufacturers. Insert grades, coatings, chipbreakers, thread profiles and dimensions can be customized according to your machining requirements.
Whether you need standard 60° ISO metric threading inserts or application-specific CNC threading solutions, we can provide suitable carbide grades and geometries for stable and repeatable thread machining.
