TPMR 160304 T5115 — TPMR turning insert, CVD-coated carbide, Tungaloy

The TPMR160304 T5115 is an ISO-standard triangular indexable insert for external and internal turning, optimised for cast iron with a balanced mix of wear resistance and edge stability.

• CVD-coated carbide for cast iron machining
• ISO-standard triangular insert, 16 mm size
• 11° clearance angle and 0.4 mm nose radius

Consistent cutting performance for cast iron components

The triangular indexable insert is supplied in an ISO format that simplifies tool selection and replacement. The CVD-coated carbide grade T5115 is formulated to offer a stable cutting edge and improved wear resistance when machining cast iron, resulting in fewer change-overs and longer uninterrupted run times. The 0.4 mm nose radius provides a dependable compromise between edge strength and surface finish; a larger radius increases edge life, whereas a smaller radius favours finer detail. Compatibility with holders is determined by form, clearance angle, tolerance class, attachment method, size and thickness, so standard ISO dimensions ensure interchangeability across common turning tool systems.

Improved chip control and process reliability

Equipped with a single-sided chipbreaker, the insert promotes controlled chip formation during both external and internal turning operations. Stable chip behaviour reduces the likelihood of rework and downtime, which contributes directly to higher throughput and consistent surface quality. Explaining the technical term: a chipbreaker guides and segments chips to avoid long, entangling swarf and to maintain cutting stability. Selecting the correct chipbreaker and grade for the workpiece and machining conditions helps to achieve predictable tool life and repeatable results, supporting process optimisation in production environments.

Practical geometry and mounting benefits for workshop use

The insert’s 16 mm triangular form with a thickness of 3.18 mm and an 11° clearance angle fits ISO-compatible holders and boring bars without modification, simplifying inventory and fixture planning. The absence of a mounting hole and the standard 60° included angle are relevant for clamping and corner strength; the triangular geometry provides three usable cutting corners, which improves cost efficiency per edge. For workshops focusing on cast iron components, the combination of ISO conformity, straightforward mounting and the T5115 grade supports predictable cycle times and reduced tooling management overhead.

FAQ

What types of turning operations is this insert suited for?
The TPMR160304 T5115 triangular insert is intended for both external and internal turning operations; its geometry and chipbreaker make it particularly suitable for machining cast iron components.

How does the T5115 grade affect tool life and edge stability?
The CVD-coated T5115 grade on the TPMR160304 insert balances wear resistance and edge stability, extending effective cutting life when machining cast iron while maintaining consistent surface integrity.

Which holder dimensions and features must be matched for correct fitting?
Compatibility is driven by insert form, clearance angle, tolerance class, attachment method, size and thickness; use an ISO-compatible triangular holder sized for 16 mm inserts with a 3.18 mm thickness to fit the TPMR160304.

Can the insert be used on materials other than cast iron?
The TPMR160304 is optimised for cast iron; selection for other materials should be based on the workpiece, machining strategy and stability, and may require a different grade or chipbreaker.
