TPMT 16T308 T5115 triangular indexable insert for turning — Tungaloy

TPMT16T308-CM T5115 is an ISO-standard triangular turning insert designed for external and internal turning, optimised for cast iron machining with a CM chipbreaker.

• CVD-coated carbide grade T5115
• ISO triangular insert, 60° included angle
• 0.8 mm corner radius for edge strength
• 11° relief angle for improved cutting clearance

Consistent performance where cast iron productivity matters

The combination of a CVD-coated carbide substrate and the T5115 grade provides a balanced mix of wear resistance and edge stability, making this insert well suited to cast iron machining. The coating reduces abrasive wear at elevated temperatures, while the substrate maintains edge integrity under interrupted cuts. As a result, the indexable cutting tip delivers longer tool life and fewer tool changes, which translates into lower cycle times and more predictable process windows in series production.

ISO conformity and holder compatibility for predictable integration

Being an ISO-standard indexable insert, compatibility with tool holders is governed by geometric parameters — form, relief angle, tolerance class, fastening method, size and thickness. The insert’s geometry and the specified 11° relief ensure that the cutting edge sits correctly in a matching external holder or boring bar. System reliability depends on correct pairing with the appropriate clamping set and replacement screws, which are part of the recommended system components for safe, repeatable clamping.

Geometry and chip control explained for process optimisation

The triangular shape with a 60° included angle and a 0.8 mm corner radius gives a favourable compromise between edge strength and profile accuracy. The CM chipbreaker is designed to control chip formation in cast iron, promoting short, easily evacuated chips under a range of cutting parameters. The insert thickness of 3.97 mm and the central hole with a cylindrical bore plus a single-sided countersink (40°–60°) support secure fastening and consistent seat location, reducing micro‑movement and improving surface finish.

Practical benefits for workshop efficiency and decision support

Using an indexable insert from a recognised model series simplifies stock management: the ISO-series designation allows straightforward substitution within compatible holders, and the modest corner radius helps to broaden application scope without frequent tool changes.

FAQ

What materials is this insert designed for?
The TPMT16T308-CM T5115 insert is formulated as a universal grade for cast iron machining, with the T5115 CVD-coated carbide combination offering balanced wear resistance and edge stability for grey and nodular cast irons.

Is the insert suitable for both external and internal turning?
Yes, the ISO triangular geometry and central hole design make this indexable insert suitable for both external turning and internal boring operations when paired with the appropriate holder and clamping set.

How does the CM chipbreaker influence machining?
The CM chipbreaker is engineered to produce short, controlled chips in cast iron, improving chip evacuation and surface finish while reducing the risk of entanglement in both automated and manual operations.

Which parameters determine holder compatibility?
Compatibility depends on geometric and dimensional matches: form, relief angle (11°), tolerance class, fastening method, size (16 mm) and thickness (3.97 mm). Use a matching ISO‑compliant holder for correct seating.

What is the benefit of the 0.8 mm corner radius?
A 0.8 mm radius increases edge robustness, improving resistance to chipping under interrupted cuts and offering a balance between durability and the ability to achieve moderate profile accuracy.
