TNMA 160412 T505 — Indexable turning insert for turning, CVD‑coated carbide (Tungaloy)

A TNMA160412 T505 indexable insert for economical external and internal turning, designed for cast‑iron applications where stable cutting and reliable edge life are required.

• CVD‑coated carbide grade T505
• Economical machining of cast iron
• Triangle shape with 60° cutting angle
• 1.2 mm corner radius, cylindrical hole

Maximise productivity in cast‑iron turning with a CVD coating that endures

The CVD‑coated carbide composition of this insert provides a balance between wear resistance and toughness, making it particularly suited to cast iron. The T505 grade is selected for its economic performance: it extends tool life under steady cutting conditions while keeping machining costs down. Thanks to the CVD‑coated surface, heat and abrasive wear are better resisted compared with uncoated grades, which supports consistent surface quality and reduced rework. These properties translate into measurable gains in productivity for serial turning tasks and medium‑batch production.

Clear guidance on compatibility and clamping for secure, repeatable results

Compatibility with the toolholder is governed by form, clearance angle, tolerance class, fastening method, size and thickness; the insert conforms to ISO dimensions for easy replacement within standard systems. The triangular plate, with a nominal size of 16 mm and a thickness of 4.76 mm, is supplied with a cylindrical hole and a 0° clearance geometry, which favours stable seating and repeatable location when mounted with the appropriate clamping set. The absence of a dedicated chipbreaker means the part is best applied where cutting is continuous and stable; for interrupted cuts or heavy chip control requirements, inserts with dedicated chipbreaking geometries are recommended.

Robust edge geometry and simple selection for predictable tool life

A corner radius of 1.2 mm and the 60° wedge angle deliver a compromise between edge strength and the ability to take moderate depths of cut, reducing the risk of edge chipping under common turning conditions. The combination of the triangular form and the T505 grade affords multiple indexing positions before tool change, supporting uptime and lowering tool‑handling frequency. Technical characteristics such as the CVD‑coated surface and carbide substrate mean wear progresses in a gradual, measurable manner, allowing process parameters to be optimised for cost efficiency and consistent part quality.

FAQ

What materials is this insert intended for?
The TNMA160412 T505 insert from Tungaloy is intended primarily for machining cast iron, with the T505 grade designed for economical cutting performance on such materials.

Does the insert come with a chipbreaker?
This indexable plate is supplied without a chipbreaker, so it is recommended for steady, continuous turning operations; inserts with chipbreaking geometries should be selected for interrupted cuts.

How is the insert mounted in the holder?
The insert is ISO‑dimensioned and located via its cylindrical hole and triangular form; compatibility depends on the holder's form, tolerance class and clamping arrangement.

What benefits does the CVD coating provide?
The CVD‑coated layer on the carbide substrate improves resistance to abrasive wear and high cutting temperatures, contributing to consistent surface finish and predictable tool life.

Can this insert be indexed multiple times?
Yes, the triangular geometry provides multiple usable cutting edges for indexing, supporting longer intervals between tool changes.
