CNMG 120404 T9215 ISO turning insert for turning applications — Tungaloy

The CNMG120404 T9215 is an ISO-standard turning insert for external and internal turning, engineered for medium-steel machining with a CVD-coated carbide grade that balances wear resistance and fracture toughness.

• CVD-coated carbide grade T9215 for durability
• ISO rhombic CNMG 80° geometry
• 0.4 mm nose radius for fine turning
• Double-sided chipbreaker with cylindrical hole

Consistent productivity through a wear-resistant grade

The Tungaloy CVD-coated T9215 grade offers a reliable blend of wear resistance and fracture toughness, designed as a first choice for medium-steel machining where continuous or lightly interrupted cuts are common. The chemical vapour deposition layer increases surface hardness and thermal stability, which directly reduces flank wear and extends edge life under higher cutting speeds. For production environments aiming for repeatable cycle times, the combination of grade and substrate reduces tool changes and contributes to a smoother machining flow, translating into measurable savings on setup time and downtime.

Controlled geometry for repeatable surface quality

The rhombic CNMG form with an 80° included angle and a 0.4 mm nose radius delivers a balanced contact zone that supports dimensional control and surface finish in turning operations. The insert is double-sided, enabling economical indexability, and its 0° clearance specification suits standard ISO holders where the contact geometry and tolerance class determine fit and stability. The presence of a cylindrical hole and standard thickness means straightforward integration into common external holders or boring bars; compatibility depends on form, angle, tolerance class, fixing method, size and thickness, so choosing the right holder and clamp set is essential for best results.

Shop-floor advantages and practical integration

As part of an ISO-turning system, this insert is intended to work together with a matched external holder, shim or clamp set and replacement screws; this systematic approach ensures clamping stability and repeatable seating. The double-sided chipbreaker design supports chip control across a range of feeds, helping to avoid entanglement and facilitate automatic chip evacuation—particularly useful in lights-out or high-throughput cells. By selecting the appropriate chipbreaker and cutting parameters for the workpiece and operation, workshops can increase tool life and reduce scrap rates, delivering both process reliability and economic benefit.

FAQ

What materials is this insert best suited for?
The CNMG120404 T9215 insert is optimised for medium-steel machining; the Tungaloy T9215 grade combines wear resistance and toughness for productive cutting in continuous and slightly interrupted operations.

Is the insert indexable and reversible?
Yes, the insert is double-sided and indexable, allowing rotation to a fresh cutting edge which improves economy and reduces tool-change frequency.

How does the CVD coating benefit cutting performance?
The CVD-coated carbide of the T9215 grade improves surface hardness and thermal stability, which lowers flank wear and supports longer edge life under elevated cutting speeds.

Which holder features are critical for optimal performance?
Compatibility depends on holder form, free angle, tolerance class, fixing method, size and thickness; the rhombic CNMG form with a cylindrical hole requires a matching seat and clamp for stable clamping and repeatable results.
