TNMG 160408 AH6225 TNMG turning insert by Tungaloy — PVD-coated carbide, 0.8 mm radius, for turning

TNMG160408 AH6225 Tungaloy turning insert is a triangular, ISO-sized indexable insert for external and internal turning, designed for reliable performance in stainless-steel machining.

• TNMG160408 geometry for stable turning
• PVD-coated carbide AH6225 for stainless steels
• Double-sided insert with 0.8 mm corner radius
• Compatible with ISO holders using cylindrical hole fastening

Consistent performance for stainless-steel turning

The triangular, ISO-format indexable insert delivers repeatable cutting behaviour when machining stainless steels, thanks to the AH6225 PVD-coated carbide that balances sharpness and edge stability. The specified 0.8 mm corner radius supports moderate roughing and finishing operations, reducing the tendency to vibrate in less rigid setups. Where process reliability matters, the combination of geometry and grade helps maintain surface quality and extend the time between indexings, contributing to more predictable cycle times on production lines.

Improved edge life and chip control for stable production

A PVD coating over a wear-resistant carbide substrate provides enhanced resistance to built-up edge and thermal wear during interrupted cuts and variable feeds. The insert’s double-sided chipbreaker design aids controlled chip formation across a range of feeds, lowering the risk of tangles and enabling safer automated discharge. This leads to a measurable improvement in effective tool life and less unscheduled downtime, supporting tighter production planning and improved overall equipment effectiveness.

Designed for easy integration and secure clamping

The insert follows ISO dimensions (160408) with a cylindrical hole for positive fastening and a standard triangular form that fits most compatible external holders and boring bars. The 0° rake angle and the specified tolerances ensure interchangeability with ISO-standard toolholders, simplifying stock management and holder selection. Clear identification by size and grade reduces setup errors and streamlines tool procurement for workshops using mixed tool inventories.

Practical benefits for workshop workflows

Using a universal grade such as AH6225 reduces the number of distinct grades required for mixed-material schedules, particularly when stainless steels are a frequent production material. The insert’s double-sided configuration doubles the number of usable edges per item, improving cost-efficiency per cutting edge. When combined with appropriate holder rigidity and cutting parameters, the result is a balance of surface finish and productivity that supports both small-batch flexibility and larger-series stability.
