TNMG160408 T515 — ISO turning insert for economical cast-iron machining (Tungaloy)

A TNMG160408 T515 triangular ISO insert designed for standard turning operations, optimised for efficient machining of cast iron with dependable chip control.

• ISO TNMG 160408 format, triangular 16 mm
• CVD-coated carbide grade T515 for cast iron
• Double-sided chipbreaker, cylindrical hole design

Proven material and coating for efficient chip control

The insert is manufactured from cemented carbide with a CVD-coated surface layer in grade T515, offering a balance between wear resistance and economical use in high-volume turning of cast iron. The coating reduces initial crater wear and helps maintain cutting-edge geometry over extended tool life, which in practical terms means fewer insert changes and predictable replacement intervals. The design supports stable chip formation, reducing downtime for chip clearing and improving process reliability in repetitive production environments.

Geometry and holder compatibility that simplify integration

Featuring a triangular 16 mm form with a 60° included angle and a 0.8 mm corner radius, this ISO-format insert matches common indexable toolholders when the holder selection aligns with the insert’s form, clearance angle, tolerance class, fastening method, size and 4.76 mm thickness. The cylindrical hole and double-sided chipbreaker allow the insert to be indexed for renewed cutting edges, maximising usable life per part. Compatibility depends on a correct match of dimensions and mounting; the insert’s ISO designation enables straightforward comparison and selection of suitable holders and clamping sets.

Practical guidance for process setup and application

Designed for turning (external and internal), the insert performs best when chipbreaker geometry, grade and cutting parameters are chosen to match the workpiece, stability and the presence of interrupted cuts. The double-sided chipbreaker supports controlled chip segmentation and evacuation, which is particularly useful during medium to heavy interrupted cuts in cast iron. Selecting appropriate cutting speeds and feeds will extend edge life; for shorter, high-efficiency cycles the grade’s balance of toughness and wear resistance helps secure consistent surface finish and dimensional stability.

Reliable production benefits and application certainty

Using an ISO-standard insert with the described features contributes to predictable tool behaviour and simplified inventory management. The combination of T515 grade and a CVD-coated surface promotes economic machining through good tool life and repeatable results; the triangular geometry with an indexable design reduces tooling costs per edge. For production planners this translates into stable cycle times, fewer unscheduled tool changes and clearer maintenance intervals, supporting continuous, efficient turning operations.

FAQ

What materials is this insert intended for? The TNMG160408 T515 is designed primarily for economical machining of cast iron, using its T515 carbide grade and CVD-coated surface to balance wear resistance and toughness.

How does the chipbreaker affect performance? The double-sided chipbreaker promotes controlled chip segmentation and evacuation, improving process stability and reducing the risk of chip-related interruptions during turning.

Can the insert be indexed or reversed? Yes, the triangular shape with a cylindrical hole and double-sided design allows indexing to access fresh cutting edges, maximising the number of usable edges per insert.

What determines compatibility with a toolholder? Compatibility is set by the insert’s form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters ensures secure clamping and correct cutting geometry.

Is the insert suitable for interrupted cuts? The T515 grade and chipbreaker design make the insert suitable for interrupted cuts in cast iron, provided the cutting parameters and clamping stability are appropriate.
