TNGN160412 ISO turning insert — TZ120 grade, 1.2 mm radius (Tungaloy)

The TNGN160412 is an ISO-standard triangular turning insert designed for external and internal turning, optimised for stable metal removal in a wide range of applications.

• ISO-compliant triangular insert
• TZ120 grade with balanced toughness
• Corner radius 1.2 mm for stronger cutting edge
• 4.76 mm thickness for secure clamping

Reliable ISO compatibility for consistent tool setups

The ISO-compliant geometry ensures straightforward integration into standard turning toolholders. Compatibility with the clamping system depends on the insert’s form, clearance angle 0°, tolerance class, fastening method, size and thickness; this makes tool selection predictable and reduces setup time. The ISO standard classification simplifies inventory management and supports repeatable assembly at scale, which contributes directly to shorter machine downtime and more stable production runs.

Grade and substrate engineered for balanced performance

The insert is manufactured in cemented carbide and supplied in TZ120 grade, a Tungaloy-developed composition that balances wear resistance and toughness for general turning tasks. The material mix provides a stable cutting edge under interrupted cuts and variable feeds, while the absence of an integrated chipbreaker in this grade allows pairing with holder-based chip control strategies. The result is fewer edge failures and extended component life under mixed‑load conditions.

Geometry and dimensions that support productivity

A triangular plate offers three usable cutting edges per insert, improving economy per index. With a nominal size of 16 mm, a plate thickness of 4.76 mm and a corner radius of 1.2 mm, the insert gives a reliable combination of rigidity and surface finish potential. The 60° included angle influences approach geometry and is favourable for a wide range of turning operations. The designation without a mounting hole requires compatible clamping systems or underlays, ensuring secure fixation and repeatable positioning for high‑precision turning.

Practical benefits for workshop performance

Where repeatability and predictable tool life matter, the combination of TZ120 grade and the insert’s profile reduces unplanned tool changes and supports stable process windows. The robust thickness and corner radius assist in absorbing moderate cutting forces, while the ISO form enables rapid replacement and standardised stockkeeping. For best results, match the insert with a suitable holder and select feed rates and cutting speeds according to the workpiece material and machine stability.
