WNMG 080408 T9215 — ISO turning insert, trigon geometry, 0° relief — Tungaloy

A WNMG 080408 T9215 is an ISO-standard trigon indexable insert for external and internal turning, optimised for medium-steel machining and suited to continuous or lightly interrupted cuts.

• CVD-coated carbide grade T9215
• Positive trigon geometry
• 0° relief for robust cutting
• 0.8 mm corner radius for finish

Productive performance for medium-steel turning

The T9215 grade is a CVD-coated cemented carbide developed for the middle range of steel applications, balancing wear resistance with fracture toughness to sustain higher material removal rates. In practical terms, this means longer effective tool life under steady production conditions and fewer indexings, which reduces downtime and tooling cost per component. The DM chipbreaker is designed to promote predictable chip form during continuous and lightly interrupted cuts, helping to preserve surface integrity and reduce the need for secondary finishing.

Geometry and compatibility for reliable setup

The trigon insert geometry with an included angle of 80° and a 0° relief gives a positive cutting profile that is forgiving in many holder types while maintaining cutting strength. Compatibility with toolholders depends on the insert’s form, relief angle, tolerance class, attachment method, size and thickness; matching those parameters ensures correct clamping and repeatable positioning. The nominal thickness of 4.76 mm and the cylindrical hole are standard for many ISO turning systems, simplifying integration into existing tool assemblies.

Durability explained: coating, edge and radius choices

A CVD coating combined with a robust carbide substrate provides thermal and abrasive protection across typical turning speeds for medium steels. The 0.8 mm corner radius contributes to improved surface finish and distributes cutting forces to reduce edge chipping in interrupted cuts. For applications requiring higher edge strength, the geometry and the chipbreaker are well suited to maintain stability; for fine finishing passes, the radius helps achieve consistent Ra values without excessive cutting forces.

Practical selection and operational guidance

When choosing the insert for a production cell, consider the workpiece stiffness, cutting parameters and fixture stability: the T9215 insert performs best under stable setups with continuous or slightly interrupted cuts. For mixed-production environments, its balance of wear resistance and toughness offers a good compromise between longevity and reliability. Where holder compatibility or specific cycle requirements are uncertain, match the insert’s size and relief to the holder specification and consider running a verification pass under representative conditions.

FAQ

Which materials is this insert best suited for?
The WNMG080408-DM T9215 insert from Tungaloy is optimised for medium steels, offering a balance of wear resistance and toughness suitable for continuous to lightly interrupted turning operations.

What is the corner radius and how does it affect finish?
This insert has a 0.8 mm corner radius; the radius helps distribute cutting forces and improves surface finish, particularly on finishing passes.

Which chipbreaker and grade are used on this insert?
The insert employs the DM chipbreaker and the T9215 CVD-coated cemented carbide grade, designed to promote stable chip control and extended tool life in steel turning.

How to ensure compatible clamping and repeatability?
Compatibility is achieved by matching the insert’s form, relief angle (0°), tolerance class, attachment method, size (08) and thickness (4.76 mm) to an appropriate toolholder; proper seating and torque on the clamping screw ensure repeatable positioning.
