TNMG 160404 T515 TNMG indexable insert for Turning by Tungaloy — CVD-coated carbide, R0.4

The TNMG160404 Tungaloy insert is an ISO-conform triangular indexable insert designed for turning, optimised for economical machining of cast iron with controlled chip formation and reliable cutting edge performance.

• CVD-coated carbide grade T515
• For economical cast iron machining
• Triangular TNMG 160404, 0.4 mm radius
• Double-sided chipbreaker, with cylindrical hole

High productivity through targeted chip control and coating benefits

The CVD-coated carbide grade T515 provides a balanced combination of wear resistance and toughness, enabling longer tool life under interrupted cuts and variable stability. With a double-sided chipbreaker and a cylindrical hole for secure clamping, the insert supports consistent chip formation and evacuation, reducing downtime for chip clearing. For production environments dealing primarily with cast iron, this configuration reduces tool changes and improves throughput while maintaining predictable surface integrity.

Mechanical compatibility and secure clamping for robust turning

Compatibility with holders depends on form, free angle, tolerance class, clamping method, size and thickness; the TNMG 160404 follows ISO dimensions to ensure straightforward pairing with standard external holders or boring bars. The 0° free rake and the 60° cutting angle deliver a favourable balance between cutting forces and edge strength, while the 0.4 mm corner radius offers a compromise between edge durability and surface finish. Clear specification of these parameters simplifies setup and shortens machine idle time.

Economic edge: why this Tungaloy grade suits everyday production

Selecting the T515 grade targets cost-effective machining of cast iron: optimised chip control and CVD surface protection enhance tool life without requiring premium tool management efforts. The triangular plate shape permits multiple indexings, lowering consumable cost per component. In practical terms, the result is improved machining stability, fewer interruptions for insert changes and a more reliable process window for medium- to high-volume turning operations.

FAQ

What materials is this insert optimised for?
The Tungaloy TNMG160404 T515 is optimised for economical machining of cast iron; the CVD-coated T515 grade is tuned for stable chip formation and extended edge life on grey and compacted graphite cast irons.

How is the insert secured in the holder?
The insert features a cylindrical hole and conforms to ISO dimensions, so it is clamped using the appropriate insert seat, clamp and screw system for TNMG-type external holders or boring bars.

What cutting geometry does the insert offer and what does that mean for surface finish?
With a 60° cutting angle, a 0° free rake and a 0.4 mm corner radius, the insert balances edge strength and achievable surface quality; the geometry supports robust turning while delivering acceptable finishes for many cast iron components.

Can this insert be indexed multiple times?
Yes, the triangular TNMG form provides multiple index positions, which reduces the cost per cutting edge and is advantageous in batch production where predictable edge changes are required.

Is the TNMG160404 compatible with standard ISO holders?
The plate follows ISO dimensions (160404) but compatibility depends on holder form, tolerance class, clamping type and size; verify holder matching before fitting to ensure correct seating and torque.
