TNMG 160420 T9215 Turning Insert by Tungaloy — CVD‑coated carbide, ISO triangular insert for medium steel

The TNMG160420 T9215 is an ISO‑standard triangular turning insert for external and internal turning, optimised for medium steel machining and continuous to mildly interrupted cuts.

• CVD-coated carbide grade T9215
• Designed for medium steel machining
• Double-sided insert with cylindrical hole
• 2 mm corner radius for robust cutting edge

Consistent tool life and process stability for medium steel

The CVD‑coated carbide grade delivers an excellent balance of wear resistance and fracture toughness, making it a first choice for productive turning of medium‑hard steels. The coating improves thermal stability at cutting edges, which reduces flank wear during sustained cuts and extends time between indexings. As part of an ISO insert system, the geometry and tolerance classes ensure predictable seating and repeatable results in matching external holders or boring bars. The result is a measurable improvement in throughput and fewer unexpected tool changes, supporting efficient machining cycles.

Geometry and design that support higher productivity

A 2 mm corner radius provides a robust cutting edge that resists chipping under variable cutting forces, while the double‑sided configuration doubles the available cutting edges per insert, lowering tooling costs per part. The 0° clearance angle and triangular form give stable support in the pocket and promote consistent chip formation when paired with the appropriate chipbreaker and feed rates. The cylindrical locating hole further secures the insert against rotation and ensures correct clamping force. Together, these features reduce vibrations and aid surface finish, translating directly into shorter cycle times and fewer reworks.

Practical compatibility and handling in workshop setups

Designed to the ISO-Drehwendeschneidplatten series specifications, the insert is compatible with standard ISO external holders, clamping kits and replacement screws when dimensions and form match. The CVD‑coated carbide body suits continuous and slightly interrupted cuts; selecting the correct chipbreaker and feed parameters will unlock both productivity and surface quality. For smaller shops and large production environments alike, the standardised form factor simplifies inventory management and tool changes. The Tungaloy grade supports consistent repeatability across batches, making it easier to plan maintenance intervals and machining strategies.

FAQ

What materials is this insert intended for?
The TNMG160420 T9215 insert is intended primarily for medium steel machining and is formulated to balance wear resistance and toughness for that application.

Is the insert indexable and how many cutting edges are available?
This triangular insert is double-sided, offering multiple indexable cutting edges to extend tool life and reduce tool costs per part.

Does the hole affect clamping and stability?
The cylindrical locating hole ensures secure clamping and correct positioning in compatible holders, improving stability during turning operations.

Can the insert be used for interrupted cuts?
The T9215 grade handles continuous to mildly interrupted cuts; for heavy interruption, adjust cutting parameters or select a grade specified for heavy interruptions.

Which holder types suit this ISO insert?
Standard ISO external holders and boring bars matching the TNMG160420 form, size and tolerance class are suitable for secure mounting and repeatable performance.
