CNMG120404 T9215 — CNMG turning indexable insert by Tungaloy, CVD-coated carbide for medium steel

CNMG120404 T9215 indexable insert for productive external and internal turning in medium steel, combining wear resistance and toughness in an ISO-standard form

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• Double-sided insert with cylindrical hole
• 0.4 mm corner radius for consistent finish

Maximise output with a wear-resistant turning grade

The T9215 grade is a CVD coating on a tough carbide substrate engineered for high productivity in medium steel applications. This combination raises tool life under continuous to light interrupted cuts by resisting abrasive wear while retaining edge strength to prevent chipping. For production environments where cycle times matter, the grade provides a favourable cost-per-component balance and supports longer intervals between indexings, reducing downtime and setup frequency.

Dependable fit and stable clamping for consistent machining

Manufactured to ISO-standard dimensions, the rhombic insert form ensures predictable engagement with matching holders. The rhombic shape, double-sided configuration and cylindrical hole provide secure location and straightforward indexing, while the 4.76 mm thickness supports rigid clamping. A 0° clearance angle and standard tolerance classes contribute to a repeatable fit across compatible toolholders, reducing vibration and improving dimensional consistency on turned parts.

Geometry tuned for surface quality and chip control

A 0.4 mm corner radius and an 80° included angle balance strength and surface finish: the radius smooths cutting action to deliver improved workpiece appearance without compromising edge life, and the geometry promotes reliable chip control when paired with the appropriate chipbreaker. The insert is designed as part of a system — the ISO insert, a matching external holder or boring bar, plus the correct shim and clamping set — ensuring safe clamping and quick replacement when wear occurs. For applications with light interruptions, choose a chipbreaker and machining parameters that match the workpiece material and stability for best results.

FAQ

Which materials is this grade best suited for?
The T9215 grade is optimised for medium steel machining; CNMG120404 with its CVD-coated carbide substrate offers a balance of wear resistance and toughness ideal for such steels.

Is the insert reversible and how often can it be indexed?
Yes, the insert is double-sided and reversible; indexing frequency depends on cutting conditions, but the robust grade extends usable life between indexes compared with standard uncoated grades.

How is compatibility with holders determined?
Compatibility is determined by insert form, clearance angle, tolerance class, attachment method, size and thickness; matching an ISO-standard holder to the CNMG geometry ensures correct seating and clamping.

What cutting conditions suit this insert best?
The insert excels under continuous to light interrupted cuts at moderate to high feed rates; selecting the correct chipbreaker and cutting parameters will optimise surface finish and tool life.
