TNMG 160412 T5115 — TNMG160412 T5115 indexable insert for Turning by Tungaloy

The TNMG160412 T5115 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for cast-iron machining with a balanced mix of wear resistance and edge stability.

• Triangle insert with 60° geometry
• CVD-coated cemented carbide grade T5115
• Double-sided chipbreaker, with cylindrical hole
• Optimised for cast-iron turning

Increased process efficiency through edge stability and coating

The combination of a CVD-coated cemented carbide and the T5115 grade delivers a durable cutting edge that withstands fluctuating loads during roughing and finishing passes. This results in lower tool consumption and longer edge life, translating into fewer interruptions for tool changes and a higher overall spindle utilisation. The coating improves thermal stability and reduces adhesive wear when machining abrasive cast-iron alloys, enabling consistent dimensional accuracy over extended cycles. The design supports predictable tool life, which helps to plan batch runs and reduce unexpected downtime.

More consistent chip control for cleaner surfaces and fewer reworks

A double-sided chipbreaker combined with the insert's triangular form and a cylindrical hole improves chip formation and evacuation, particularly in interrupted cuts common with cast-iron components. Better chip control reduces the risk of re-cutting, protects the cutting edge and contributes to superior surface quality without aggressive feeds. Stable chip flow also lowers the risk of built-up edge and avoids unplanned machine stops, supporting shorter cycle times and fewer manual interventions for chip clearing.

Straightforward integration into ISO tool systems for flexible setups

The ISO designation and standard dimensions make mounting and replacing the insert in compatible holders simple: compatibility is determined by shape, clearance angle, tolerance class, fixing method, size and thickness. The 60° geometry and 1.2 mm corner radius suit a range of turning tasks from light finishing to robust roughing when paired with the appropriate holder and machining parameters. Using ISO-standard inserts helps maintain stock rationalisation and speeds up tooling changes on multiple machines, supporting a lean shopfloor strategy and predictable process planning.

FAQ

What materials is this insert intended for?
The TNMG160412 T5115 insert is optimised for machining cast iron; the CVD-coated cemented carbide and T5115 grade balance wear resistance and edge stability for this material group.

Which toolholders fit this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness; the ISO TNMG160412 designation allows selection of matching external holders or boring bars complying with the standard.

How does the chipbreaker design affect performance?
The double-sided chipbreaker ensures controlled chip formation and evacuation, improving surface finish and minimising the risk of re-cutting in interrupted cuts typical of cast-iron turning.

Is the insert indexable and reversible?
Yes, the triangular shape provides multiple cutting edges per insert; the double-sided design supports reuse after indexing, improving economy in series production.

What information is needed to replace an existing insert?
Provide the ISO designation (TNMG160412), grade (T5115), corner radius and plate thickness to ensure the replacement insert matches the holder and machining task.
