TPMT110204 T9215 – ISO turning insert, CVD-coated carbide, 60° triangle (Tungaloy)

A TPMT110204 T9215 ISO turning insert engineered for external and internal turning of medium steels, offering high wear resistance and robustness for continuous to slightly interrupted cuts.

• CVD-coated carbide for high wear resistance
• Triangular 60° geometry, 0.4 mm corner radius
• 11° clearance angle with cylindrical hole + countersink
• One-sided chipbreaker for continuous and light cuts

Greater productivity from stable cutting geometry

The triangular 60° geometry combined with a 0.4 mm cutting edge radius and a plate thickness of 2.38 mm provides a stable contact area that reduces vibration and improves edge life. For ISO-standard tool systems, this geometry supports repeatable seating and clamping, which translates into reduced set-up time and fewer rejected parts. The controlled geometry is especially beneficial in production environments where consistent surface finish and dimensional accuracy are required. The positive effect on cycle time and tool life contributes directly to improved process efficiency.

Extended tool life through advanced coating and grade

The T9215 grade, a CVD-coated carbide, balances wear resistance and fracture toughness to perform well in the middle range of steel machining. This combination allows productive cutting at higher material removal rates while maintaining tool life under continuous and slightly interrupted conditions. For operations prioritising longer intervals between tool changes, the coated grade reduces unexpected downtime and lowers overall tooling costs per component, supporting a measurable cost‑benefit over long production runs.

Secure mounting and ISO compatibility for reliable operation

As an ISO turning insert, compatibility with a holder is determined by shape, relief angle, tolerance class, fixation, size and thickness. The insert features a cylindrical hole with a one-sided countersink (40°–60°) to ensure positive clamping and stable seating in dedicated external holders or boring bars. A complete system typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamping set and spare screws, enabling dependable repeatability across tool changes and minimising set-up variations.

Practical chip control and application advice

The one-sided chipbreaker is designed for efficient chip formation and evacuation when machining medium steel, reducing re-cutting of chips and helping maintain surface quality. For best results, match the chipbreaker and grade to the workpiece material, cutting parameters and machine stability; the insert is suited to both external and internal turning operations. For those unfamiliar with technical terms: the clearance angle (11°) prevents rubbing behind the cutting edge, while the included angle (60°) affects approach to the workpiece and strength of the cutting edge.

FAQ

What materials is this insert best suited for?
The TPMT110204 T9215 insert from Tungaloy is optimised for medium steel machining thanks to its CVD-coated carbide grade, offering a balance of wear resistance and toughness.

How does the chipbreaker influence cutting performance?
The one-sided chipbreaker on this insert promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of chip re-cutting during turning operations.

Is the insert compatible with standard ISO holders?
Compatibility is ensured by matching the insert’s form, clearance angle, tolerance, fixation, size and thickness to an ISO-standard holder; the TPMT110204’s hole and countersink support secure clamping.

Why is the 11° clearance angle important?
An 11° clearance angle prevents rubbing behind the cutting edge, reducing friction and heat generation, which contributes to longer edge life for the T9215 grade.

Can this insert handle interrupted cuts?
The T9215 grade and robust geometry are suitable for continuous to light interrupted cuts; heavier interruptions may require a different grade or edge preparation.
