VBMT160408-TM AH6225 — ISO turning insert, PVD-coated carbide (Tungaloy)

VBMT160408-TM AH6225 is an ISO‑standard rhombic indexable insert for external and internal turning, optimised for stainless applications and medium machining tasks.

• PVD-coated carbide grade AH6225
• Universal for stainless applications
• Rhombic 16 mm ISO format
• Edge radius 0.8 mm

Stable cutting performance for stainless applications

The PVD‑coated AH6225 grade is engineered to deliver a sharp but robust cutting edge, balancing edge stability with the ability to cut reactive alloys. This results in reduced built‑up edge and improved surface finish when machining tougher stainless grades. The PVD layer increases wear resistance under fluctuating temperatures and interrupted cuts, making the insert suitable for variable shop conditions and mixed production runs. For process planners, the combination of coating and carbide substrate means longer tool life and more predictable regrinding intervals, supporting higher first‑pass yields.

Seamless integration with ISO tool systems

The rhombic 16 mm ISO format and standard geometry allow quick replacement and minimal adjustment when swapping inserts. Compatibility with holders depends on form, 5° clearance, tolerance class, fastening method and plate thickness; this standardisation reduces setup time and lowers the risk of assembly errors. The insert’s 35° orientation and 4.76 mm thickness are common in external and internal turning tool assemblies, enabling economical toolholder pooling across similar operations. For production engineers, this means faster changeovers and a simplified tooling inventory.

Reliable chip control and repeatable results

The TM chipbreaker is optimised for medium cuts and supports consistent chip formation with a 0.8 mm corner radius that helps maintain edge strength during depth changes. Effective chip control reduces recutting, improves surface quality and lowers the likelihood of part damage in automated turning processes. Choosing the correct chipbreaker and grade for the material and machine stability will yield measurable productivity gains and reduce cycle time variability. For applications requiring controlled chip flow, the indexed nature of the insert ensures quick rotation to a fresh cutting edge with minimal downtime.
