TNMG 160404 T515 Turning insert TNMG160404 T515 for Turning — Tungaloy

TNMG160404 T515 is an ISO-format indexable turning insert designed for economical machining of cast iron with a CVD-coated carbide grade from Tungaloy.

• TNMG 160404 T515 CVD-coated carbide
• 60° triangular insert with 0° rake
• Double-sided chipbreaker for cast iron
• 0.4 mm corner radius, cylindrical hole

Economical cast-iron machining with proven grade benefits

The T515 grade combines a CVD-coated surface with a tough carbide substrate to balance wear resistance and fracture toughness for interrupted or stable turning of cast iron. The coating reduces flank wear at higher cutting speeds while the substrate maintains edge integrity under vibration. For production environments seeking lower unit costs, this geometry-and-grade pairing supports longer life per edge and consistent surface finish, reducing tool-change frequency and unplanned downtime.

Geometry that promotes process stability and repeatable results

The triangular form with a 60° included angle provides three usable cutting edges per insert and a compact cutting profile that helps maintain rigidity in both external and internal turning operations. The 0° rake and 0.4 mm corner radius give a conservative, robust edge that tolerates varying feed rates and interrupted cuts. The 4.76 mm thickness increases clamping stability, so the system resists deflection under moderate cutting forces; this translates into repeatable component tolerances and predictable wear rates.

System compatibility and practical handling for workshop integration

These inserts conform to ISO plate standards, making them interchangeable with compatible holders when form, clearance angle, tolerance class, fastening method, size and thickness match. The insert is double-sided with a cylindrical hole, allowing economical indexing and simple clamping; replacement is performed with the matching shim/clamp set and screws. The recommended system consists of the insert, a suitable external holder or boring bar, a shim/clamp kit and spare fastening screws, enabling quick integration into existing toolholders and reduced set-up time.

Selecting the correct chipbreaker and operating window

The double-sided chipbreaker included on this grade is optimised for stable chip control in grey and nodular cast irons; select the chipbreaker and the T515 grade based on part rigidity, depth of cut and desired cutting speed. The CVD coating supports elevated cutting speeds, but dry or low-coolant conditions should be validated on the specific workpiece and machine to ensure consistent chip formation and surface integrity.

Practical advice for specifiers and buyers

Specification should list the ISO designation, edge radius and hole style to ensure correct holder matching. When encountering interrupted cuts or vibration-sensitive set-ups, consider a smaller corner radius or alternate clamping to increase edge strength. For questions on holder compatibility or process parameters, technical documentation and machining data sheets are recommended to define feeds and speeds for the specific cast-iron grade and machine power.

FAQ

What materials is this insert intended for?
The TNMG160404 T515 insert is intended primarily for machining cast iron; the CVD-coated carbide T515 grade is optimised for stable chip control and economical performance in such materials.

How many usable edges does the insert provide?
The triangular geometry supplies three usable cutting edges per insert; the double-sided design allows indexing for extended service life.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and matching size/thickness; use ISO-compatible external holders or boring bars specified for TNMG160404 dimensions.

What is the corner radius and how does it affect cutting?
The corner radius is 0.4 mm, which provides a balance between edge strength and surface finish—suitable for general turning and interrupted cuts where a modest radius improves robustness.

Is the insert coated and what benefits does the coating provide?
Yes, the insert features a CVD-coated carbide grade (T515), offering improved wear resistance at higher cutting speeds and enhanced edge life in cast-iron applications.

Can this insert be used for internal and external turning?
Yes, the plate is suited for both external and internal turning operations provided the correct holder and setup are used.
