VBMT160404-TM AH6225 — ISO turning insert for stainless steels, Tungaloy

VBMT160404-TM AH6225 is an ISO-standard indexable turning insert designed for external and internal turning operations, offering a balance of sharpness and edge stability for variable cutting conditions.

• ISO rhombic insert, 35° cutting angle
• PVD-coated carbide grade AH6225
• Optimised for stainless steels machining
• Cylindrical hole with single-side countersink

Predictable machining with a universal PVD grade

The AH6225 grade combines a PVD-coated carbide substrate with a microstructure tuned for stainless steels, delivering a cutting edge that is both sharp and wear-resistant. This composition reduces the tendency for built-up edge and helps maintain dimensional accuracy during medium-duty turning. For operations where tool life and surface integrity are equally important, the coated grade provides a consistent compromise between edge strength and cutting performance. The coating also aids in heat resistance, extending useful life under varying feeds and speeds.

ISO conformity for simple holder compatibility

Designed to the ISO indexable insert standards, the insert’s fit is determined by form, clearance, tolerance class, fastening, size and thickness. The ISO-standard designation simplifies selection of compatible external holders and boring bars, reducing setup times and avoiding mismatches. Clear guidance on geometry and tolerance allows predictable clamping and repeatable positioning, which supports process stability and eases tool change procedures on the shop floor.

Geometry tuned for turning productivity

The rhombic plate form with a 35° included angle and a corner radius of 0.4 mm supports a versatile range of turning tasks, from profiling to medium-facing. The TM chipbreaker promotes controlled chip formation under mixed cutting conditions, improving surface finish and reducing interruptions from long or tangled chips. A modest corner radius helps achieve good surface quality while allowing moderate material removal rates, making the insert suitable for a broad set of stainless-steel turning applications where both finish and productivity matter.

Stable mounting and robust plate design

A plate thickness of 4.76 mm and insert size of 16 mm provide the rigidity required for steady cutting performance. The carbide substrate delivers the inherent toughness necessary for interrupted cuts, while the cylindrical hole with a single-side countersink (40°–60°) facilitates secure fastening and precise seating in the clamp assembly. These design choices reduce vibration and improve repeatability, which is particularly beneficial in batch production or tool indexing routines.
