CNMG 090404 T6215 — ISO turning insert (80°), CVD-coated carbide — Tungaloy

A CNMG090404 T6215 indexable turning insert engineered for stable to lightly interrupted stainless-steel machining and versatile external and internal turning applications

• CVD-coated carbide for high wear resistance
• Optimised for stainless-steel turning operations
• CNMG 09 profile, 80° rhombic geometry

Consistent tool life through targeted grade and coating

The combination of the T6215 grade and a CVD-coated carbide substrate provides enhanced wear resistance when machining stainless steel, reducing flank and crater wear under steady cutting conditions. This tailored coating increases resistance to abrasive and adhesive wear mechanisms common with stainless alloys, which helps to extend the period between indexings and lowers tooling consumption. As a result, process stability and component repeatability are improved while maintenance intervals are lengthened

Clear ISO geometry for straightforward holder compatibility

The insert adopts the ISO CNMG shape with a rhombic bevel and an included angle of 80°, a thickness of 4.76 mm and a corner radius of 0.4 mm, making mechanical compatibility with standard external holders and boring bars predictable. The insert features a cylindrical hole and a 0° relief angle; compatibility with a holder is defined by form, free angle, tolerance class, fastening method, size and thickness. This standardisation simplifies tool inventory and reduces the need for bespoke clamping solutions

Improved chip control and operational efficiency

Equipped with a double-sided chipbreaker, the insert supports controlled chip formation for many turning tasks, enabling efficient evacuation and stable cutting forces. In practice, the indexable design permits rapid rotation to a fresh edge, which minimises machine downtime and sustains dimensional accuracy. For finishing and medium-turning operations on stainless alloys, this combination delivers good surface quality and repeatable results under consistent machining setups

Practical guidance for process integration

The grade is intended for stable to lightly interrupted cuts; selection of feed and speed should match workpiece material, machine power and rigidity. Choose a chipbreaker and grade aligned with the component material and the intended machining task to exploit the T6215 advantages fully.

FAQ

What materials is this insert best suited for?
The CNMG090404 T6215 insert is formulated for machining stainless steel under stable to lightly interrupted cutting conditions, delivering improved wear resistance and surface finish

How does the T6215 grade affect tool life?
The T6215 grade, with its CVD coating, reduces abrasive and adhesive wear on the cutting edge, which typically leads to longer edge life and fewer indexings compared with uncoated grades

What geometry details determine holder compatibility?
Compatibility depends on the CNMG rhombic form, the 80° included angle, thickness (4.76 mm), hole style (cylindrical) and the 0° relief angle; matching these dimensions to the clamping system ensures secure mounting

Is the chipbreaker suitable for finishing operations?
The double-sided chipbreaker supports controlled chip formation and can be used for finishing and medium-turning tasks to promote consistent surface quality

Can this insert be used for interrupted cuts?
The insert is designed for stable to lightly interrupted cuts; for heavy or heavily interrupted machining, evaluation of machining parameters and machine stability is recommended
