TNMG270616 AH120 TNMG indexable turning insert for Turning by Tungaloy — PVD‑coated carbide, 60° triangle

A TNMG270616 AH120 indexable insert designed for external and internal turning where a sharp cutting edge, process security and stable chip control are required

• PVD‑coated carbide for high wear resistance
• ISO triangle 27 mm with 60° cutting geometry
• Double‑sided chipbreaker for stable chip control
• Cylindrical hole, 6.35 mm thickness for secure clamping

Engineered for consistent turning performance

The insert is based on a PVD‑coated carbide grade intended to deliver wear‑ and chipping resistance during continuous turning operations. The AH120 grade was developed for applications where a sharp, durable edge and process security are priorities; this reduces edge damage and maintains surface finish over longer tool life. The coating enhances heat tolerance and adhesion, which permits sustained cutting speeds and improves repeatability in batch production. With a clear focus on measurable outcomes, the result is fewer tool changes and more predictable cycle times, benefitting production planning and cost control.

Secure clamping and ISO compatibility that reduces setup risk

Designed to the ISO indexable insert family, the triangular TNMG form with a 27 mm inscribed circle and 60° included angle provides a familiar geometry that fits common external holders and boring bars when the holder form, relief angle and tolerance class match. The insert’s cylindrical hole and a plate thickness of 6.35 mm ensure confident clamping and repeatable positioning, reducing vibrations and the risk of misalignment in the interface. The 1.6 mm corner radius provides a balance between edge strength and achievable surface finish, helping to avoid premature edge breakouts while maintaining dimensional control for turned components.

Application range and reliable process results

This grade and geometry suit a wide range of turning tasks: external and internal turning across diverse steels and allied materials where a stable cutting edge is required. The double‑sided chipbreaker supports consistent chip formation and evacuation, which is particularly advantageous in medium‑to‑stable setups and when reproducible chip control is essential for automated or multi‑part cycles. Selecting the correct chipbreaker and grade according to workpiece material and machining stability ensures the most economical operation with predictable tool life. Overall, the insert supports productivity gains through fewer interruptions, improved surface quality and dependable performance under typical shopfloor conditions.
