TNMA 220412 T5115 triangular indexable insert — 60° geometry, CVD-coated carbide (Tungaloy)

The TNMA220412 T5115 is an ISO triangular indexable insert for turning, optimised as a universal grade for cast iron machining.

• Triangular ISO insert, 60° cutting angle
• CVD-coated carbide grade T5115
• Optimised for cast iron machining
• 1.2 mm nose radius, cylindrical hole

Consistent machining performance for cast iron components

The combination of CVD-coated carbide and the T5115 grade delivers a balance between wear resistance and edge stability, which translates into predictable tool life and repeatable part quality when machining cast iron. The coating reduces flank wear and improves resistance to built-up edge; this means fewer interruptions for insert changes and steadier cycle times. For production environments, the result is enhanced process security and reduced scrap rates without sacrificing cutting performance.

Secure fit and ISO compatibility for flexible tool planning

The insert’s ISO TNMA form and defined dimensions ensure compatibility with standard turning toolholders; compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness. The triangular shape and cylindrical hole provide positive location and secure clamping, while the 4.76 mm plate thickness supports robust seating under heavier cuts. These characteristics help to maintain repeatable positioning and reduce the risk of vibration or movement during high-stability operations.

Edge geometry tuned for surface finish and strength

A 1.2 mm nose radius offers a pragmatic compromise between achievable surface finish and edge strength: larger radii improve surface quality at higher feeds, while still providing the mechanical strength required for interrupted cuts typical in cast iron work. The 60° cutting angle influences chip flow and cutting forces; combined with the insert geometry, it supports controlled material removal and consistent dimensional accuracy on both external and internal turning tasks.

Practical application notes and process benefits

Designed for general turning, these inserts are suited to both roughing and finishing when matched with the appropriate chipbreaker and cutting data. The item is supplied without a chipbreaker, so selection of a matching chip control geometry should be based on workpiece stability and the chosen machining strategy. Using the ISO-standard form simplifies tool inventory and allows faster changeovers, contributing to overall shop-floor productivity and lower setup times.

FAQ

What materials is this insert primarily intended for?
The insert grade T5115 is a universal choice optimised for cast iron machining, delivering a balance of wear resistance and edge robustness for typical turning operations.

Is the TNMA220412 compatible with standard ISO toolholders?
Yes. The ISO TNMA form and specified dimensions allow compatibility with matching ISO toolholders; correct fit depends on form, relief angle, tolerance class, clamping method, size and thickness.

Does this insert come with a chipbreaker?
This particular item is supplied without a chipbreaker, so chip control should be achieved by selecting the appropriate insert geometry or machining parameters for the workpiece and operation.

How does the 1.2 mm nose radius affect machining results?
A 1.2 mm radius improves surface finish potential at moderate to higher feeds while maintaining sufficient edge strength for interrupted cuts common in cast iron turning.

What is the plate thickness and why does it matter?
The 4.76 mm plate thickness contributes to insert stability in the pocket, supporting heavier cuts and more consistent seating under load.
