CNMG 120412 T6215 Turning insert — Tungaloy (ISO CNMG, CVD-coated carbide)

A CNMG120412 T6215 indexable insert for ISO-standard turning, designed for productive machining of rostfreier Stahl under stable to lightly interrupted cutting conditions

• ISO CNMG 120412 geometry for standard turning
• CVD-coated carbide grade T6215 for rostfreier Stahl
• Double-sided chipbreaker for stable chip control
• Rhombic plate with 80° cutting edge and 1.2 mm radius

Prolonged tool life through wear-resistant grade and geometry

The combination of CVD-coated carbide and the ISO CNMG geometry delivers a measurable improvement in wear resistance and process stability. The T6215 grade is formulated for machining rostfreier Stahl, reducing adhesive wear and delaying flank deterioration so that intervals between indexings are longer. The moderate 1.2 mm corner radius and robust 80° cutting edge help distribute cutting forces and maintain consistent cutting conditions, which supports uninterrupted production and reduces the frequency of insert changes.

Straightforward integration into ISO turning systems

Compatibility is controlled by form, clearance, tolerance, fastening method, size and thickness; the plate’s rhombic shape, 4.76 mm thickness and cylindrical hole ensure secure seating in standard CNMG holders. As an indexable insert with double-sided use, the component reduces tooling inventory per application while offering simple re-indexing. The system build typically comprises the ISO insert, a dedicated external holder or boring bar, an underlay/clamping set and replacement screws for fast changeovers and minimal machine downtime.

Consistent surface finish and reliable chip control

The double-sided chipbreaker geometry combined with the CVD-coated substrate promotes stable chip formation and lowers the risk of built-up edge when cutting rostfreier Stahl. Stable chip control improves surface integrity and dimensional repeatability, particularly in steady cutting conditions. Where occasional interruptions occur, the grade’s toughness supports predictable edge behaviour, contributing to repeatable part quality and fewer downstream grinding or polishing operations.

Application advice and selection for production environments

Select the chipbreaker and insert grade according to workpiece material, machining strategy and machine-tool rigidity; the T6215 grade is optimised for turning rostfreier Stahl under stable to lightly interrupted cuts. The plate is double-sided, enabling multiple indexings; its CNMG120412 form is widely supported by ISO-compatible holders. For precise cutting parameters, holder matching and recommended feeds and speeds, technical consultation is available — Metav Werkzeuge can supply parameter sheets and verify holder compatibility to support efficient implementation.

FAQ

What workpieces is this insert intended for?
The Tungaloy CNMG120412 T6215 insert is designed specifically for turning operations on rostfreier Stahl, offering wear resistance and good chip control under stable to lightly interrupted cuts.

How is the insert indexed and how many useful edges are available?
This CNMG insert is double-sided; each side may be indexed according to the holder design, allowing multiple usable edges before replacement, which extends effective tool life in production.

Which holders and accessories are required for use?
The plate fits ISO CNMG-compatible external holders or boring bars; a matching underlay/clamping set and suitable mounting screws are part of the system for secure fixation and optimal cutting geometry.

Does the T6215 grade reduce built-up edge when machining rostfreier Stahl?
Yes, the CVD-coated T6215 grade improves resistance to adhesive wear and helps control built-up edge, contributing to more consistent surface finish and extended edge life.

Are specific cutting parameters available for this insert?
Recommended feeds and speeds depend on machine rigidity, coolant use and workpiece condition; Metav Werkzeuge can provide application-specific cutting data for the Tungaloy CNMG120412 T6215 insert.
