TPMR 160308 T5115 — ISO turning insert for robust turning, CVD-coated carbide, triangular form (Tungaloy)

TPMR160308 T5115 is an ISO indexable insert engineered for external and internal turning of cast iron, offering a balanced mix of wear resistance and edge stability in a compact triangular format.

• ISO triangular insert for robust turning
• CVD-coated carbide for cast iron
• 0.8 mm corner radius for fine finishes
• 11° relief angle; compatible with ISO holders

Consistent machining performance on cast iron components

The CVD-coated carbide grade T5115 is formulated as a universal solution for cast iron, delivering a balance between wear resistance and cutting-edge stability. As a result, cycle times are maintained while tool life is extended, which supports predictable production runs. The integrated one-sided chipbreaker improves chip control during both roughing and semi-finishing operations, reducing the risk of built-up edge and aiding coolant access. Explained plainly, the coating increases resistance to abrasive wear and oxidation at typical turning temperatures, while the substrate provides the toughness required when interrupted cuts or variable feed rates occur.

Geometry engineered for repeatable surface quality and strength

The triangular plate geometry with a 0.8 mm corner radius provides a dependable compromise between strength and surface finish; the radius reduces edge chipping risk while enabling consistent workpiece appearance. The 11° relief angle minimises flank contact and heat generation, supporting dimensional stability across longer batches. The insert’s included angle of 60° contributes to radial strength, making the geometry suited to both external turning and internal operations when paired with the correct holder. These features combine to reduce scrap rates and rework, improving overall process efficiency in precision turning applications.

System compatibility and straightforward integration into existing toolsets

Compatibility with toolholders is determined by form, relief angle, tolerance class, fastening method, size and thickness; the ISO designation simplifies selection for standard external holders and boring bars. The plate’s 3.18 mm thickness, triangular 16 mm size and hole-free design suit many common clamping systems, enabling fast changeovers and minimal setup time. Used as part of an indexed tooling system — plate, holder, clamp and replacement screws — the configuration supports lean workflows and predictable inventory management. Selecting the appropriate chipbreaker and grade according to workpiece material and machining stability ensures optimal performance from the tool system.

Economical operation and predictable process behaviour

By combining a robust substrate with a protective CVD coating, the insert offers a reliable life span under typical cast iron conditions, which contributes to lower tooling cost per component. The standardised ISO format reduces the number of distinct holders required and simplifies spare-part logistics. For production environments where repeatability and uptime matter, the plate’s balanced properties assist in achieving consistent part quality with reduced intervention. Practical selection notes: match the chipbreaker and grade to the machining strategy, and verify holder compatibility by checking form, free angle, tolerance and clamping specifics.

FAQ

What materials is this insert intended for?
The TPMR160308 T5115 insert from Tungaloy is designed primarily for cast iron applications, offering a balance of wear resistance and cutting-edge stability suited to this material class.

Which holder types are compatible with the TPMR160308 geometry?
Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the ISO designation ensures broad compatibility with standard external holders and boring bars when these parameters match.

How does the CVD coating affect tool life?
The CVD-coated carbide substrate enhances resistance to abrasive wear and oxidation at elevated temperatures, which typically extends tool life and helps maintain consistent cutting performance over longer production runs.

What surface finish can be expected with a 0.8 mm corner radius?
A 0.8 mm corner radius provides a reliable compromise between edge strength and finish quality, enabling fine surface appearances while reducing the likelihood of corner chipping during interrupted cuts.

Is the insert suitable for both roughing and finishing operations?
With the correct chipbreaker selection and machining parameters, the insert’s balanced properties allow effective use across roughing and semi-finishing tasks in cast iron turning.
