CNMG120416 T9215 indexable turning insert — CVD-coated carbide, 80° rhombic, Tungaloy

The CNMG120416 T9215 is a rhombic ISO indexable insert designed for general turning applications, offering a CVD-coated carbide grade tailored to medium steel machining and reliable performance in continuous to slightly interrupted cuts.

• CVD-coated carbide for wear resistance
• ISO CNMG form for standard toolholders
• Double-sided chipbreaker for versatile cuts
• 1.6 mm corner radius for secure engagement

High productivity through a wear-resistant grade

The selection of a CVD-coated carbide grade, designated T9215, translates into consistently high wear resistance combined with fracture toughness, making it a sensible choice for medium steel turning where productivity matters. This coating technology forms a hard, adherent layer that reduces flank wear and improves edge life under continuous cutting conditions. As a result, the insert supports longer tool intervals and steadier surface finish outcomes, contributing to reduced downtime and a more predictable production rhythm.

Geometry engineered for compatibility and stability

The rhombic CNMG geometry with an included angle of 80° and a clearance angle of 0° is a widely accepted standard, ensuring compatibility with many ISO-compliant holders and boring bars. Key dimensional data such as the inscribed circle size of 12 mm, a plate thickness of 4.76 mm and a corner radius of 1.6 mm combine to provide a stable contact area and dependable edge strength. The presence of a cylindrical central hole facilitates secure clamping and precise seating in the pocket, which reduces vibration and promotes repeatable cutting performance across batches.

Process reliability and efficient chip control

The insert’s double-sided chipbreaker provides two active cutting edges per side, doubling the usable life compared with single-sided designs and enabling economical indexing. The chip geometry has been optimised for medium steel, supporting effective chip segmentation and evacuation under typical cutting parameters. In practical terms, this reduces the likelihood of built-up edge and improves surface quality. The Tungaloy grade balances chip control and edge stability, delivering consistent removal rates while maintaining surface integrity and tool life.

Guidance for selection and safe use

The insert forms part of an ISO-standard system that includes the insert, a suitable external holder or boring bar, a clamping wedge and replacement fasteners; compatibility is determined by form, clearance, tolerance class, fastening method, size and thickness. For turning applications in medium-strength steels select the T9215 grade and the double-sided chipbreaker for routine finishing and semi-finishing operations. Ensure holders are correctly torqued and indexed at the first sign of wear; appropriate speeds and feeds for the grade will depend on machine stability and workpiece condition. Storage in a clean, dry environment and regular inspection of seating surfaces will aid consistent performance.

FAQ

What materials is this insert intended for?
The CNMG120416 T9215 insert from Tungaloy is primarily intended for medium steel machining; the CVD-coated carbide grade T9215 combines wear resistance and toughness suited to continuous and slightly interrupted turning.

How does the double-sided chipbreaker affect tool life?
A double-sided chipbreaker increases usable cutting edges per insert and supports controlled chip formation, which enhances overall tool life and reduces the frequency of indexing for the CNMG120416 T9215.

Is the insert compatible with standard CNMG holders?
Yes, the CNMG120416 designation and dimensions such as 12 inscribed circle and 4.76 mm thickness make the insert compatible with ISO CNMG holders that match the form, tolerance and clamping specifications.

What benefits does the T9215 grade provide in production?
The T9215 CVD-coated carbide grade delivers a balance of high wear resistance and fracture toughness, improving process reliability and enabling higher uninterrupted cutting times in routine turning operations.

Which features ensure stable seating and reduced vibration?
The combination of the rhombic plate form, cylindrical central hole and standard thickness contributes to secure clamping and repeatable seating, which helps to reduce vibration and improve surface finish when using the CNMG120416 insert.
