TNGG160412 GT720 Tungaloy — ISO indexable turning insert, 60° triangle

TNGG160412 is an ISO-standard triangular insert for turning, engineered for finishing to light machining of steel and optimised for high surface quality using the GT720 cermet grade.

• ISO triangular 60° insert
• GT720 cermet for fine finishing
• 1.2 mm corner radius for precision
• Double-sided insert with cylindrical hole

Consistent finishing and long-lasting edge quality

The combination of the GT720 cermet grade and the triangular 60° geometry delivers a reliable balance between surface finish and dimensional accuracy. Cermet, a ceramic‑metal composite, provides a fine, wear‑resistant cutting edge that is particularly suitable for finishing operations on steel, where consistent flank wear and repeatable tolerances matter. The result is a predictable machining outcome with reduced need for repeated finishing passes, supporting stable process windows and predictable tool-change planning.

Secure seating and straightforward indexing for efficient set-up

Designed as an ISO indexable plate with a cylindrical hole and standard retention features, this triangular insert ensures secure clamping in compatible holders. The double-sided design doubles the number of usable edges per insert, while the 4.76 mm thickness and 1.2 mm corner radius provide mechanical strength under light to moderate cutting loads. Compatibility with ISO holders is determined by form, clearance angle, tolerance class and size; matching these parameters enables quick tool changes and reproducible tool offsets, reducing set-up time on the shop floor.

Process robustness across common turning tasks

Intended for external and internal turning, the insert performs best in finishing to light machining of steel when paired with the appropriate chipbreaker and cutting conditions. The double-sided chipbreaker and the GT720 composition promote stable chip formation and even wear, which supports higher component quality and fewer interruptions. When combined with a properly matched holder and cutting data, the insert contributes to productive machining cycles and consistent part quality, aligning with modern requirements for process security and throughput.

FAQ

What machining tasks is this insert best suited for? The TNGG160412 GT720 Tungaloy insert is optimised for finishing to light machining of steel, prioritising surface quality and dimensional stability.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the plate conforms to ISO indexable turning insert dimensions for standard triangular holders.

How does the GT720 cermet grade affect performance? GT720 cermet offers a fine, wear‑resistant edge that improves surface finish and promotes uniform flank wear during finishing operations on steel.

Can the insert be indexed to use multiple edges? Yes, the triangular shape and double‑sided design allow indexing to additional cutting edges, extending usable life per insert.

What features support secure clamping and repeatability? The cylindrical hole and standard ISO geometry, together with the 4.76 mm thickness and tolerance compatibility, provide mechanical stability and reproducible positioning in suitable holders.
