TPMT090208 AH6225 Tungaloy – ISO triangular turning insert, PVD‑coated carbide, 60° geometry

The TPMT090208 AH6225 is an ISO‑norm triangular turning insert designed for external and internal turning, optimised for medium‑duty machining of stainless steels with a focus on stable chip formation.

• 60° triangle geometry for versatile turning
• PVD‑coated carbide AH6225 for stainless steels
• 0.8 mm corner radius for a robust cutting edge
• Single‑sided chipbreaker with central hole fit

Higher output through a balanced grade and coating

The combination of a PVD‑coated carbide grade and a deliberately balanced microgeometry delivers measurable productivity benefits in moderate turning operations. The AH6225 grade is formulated to give a sharp yet stable cutting edge, which reduces cutting forces under varying conditions and extends effective tool life. This results in fewer insert changes per shift and more consistent cycle times when machining stainless steels and similar alloys. The result is improved process stability and a lower cost per component in continuous production.

Reliable clamping and dimensional accuracy for repeatable results

The ISO triangular form with an included angle of 60°, a 0.8 mm corner radius and a relief angle of 11° ensures secure seating in standard external holders and boring bars. The insert thickness of 2.38 mm and the specified hole style — cylindrical hole with single‑side countersink (40°–60°) — provide repeatable positioning and straightforward clamping. Because holder compatibility depends on form, relief angle, tolerance class, fastening and plate size, this insert integrates into standard ISO systems with predictable accuracy, giving tighter tolerances and improved surface finish on turned parts.

Practical selection and machining advantages

Designed with a single‑sided chipbreaker, the insert supports controlled chip formation during interrupted and continuous cuts, reducing the risk of built‑up edge and improving surface quality. The geometry and grade make it suitable for both external and internal turning tasks where medium material removal rates are required. Choosing the correct chipbreaker and maintaining cutting parameters aligned with the grade’s capabilities leads to stable machining, consistent repeatability and a reduced need for rework — advantages that translate to time and cost savings in production.
