VBMT 110308 AH6225 – ISO turning insert for stainless‑steel applications by Tungaloy

VBMT 110308 AH6225 is an ISO‑standard rhombic turning insert designed for medium cutting conditions and variable machining environments

• ISO‑standard rhombic insert for turning
• AH6225 PVD‑coated carbide grade
• 0.8 mm corner radius for edge stability
• Cylindrical hole with 40°–60° countersink

Reliable cutting performance under varying conditions

The PVD‑coated carbide grade AH6225 is developed specifically for stainless steel machining and combines a sharp cutting edge with a degree of edge stability suited to medium‑duty turning. The coating increases thermal and abrasive resistance, which helps to reduce built‑up edge and prolong the effective life of the tool when processing work‑harden‑prone materials. In practice, this translates into fewer interruptions for insert changes and a steadier part finish, while the controlled edge geometry supports consistent chip formation with the PS chipbreaker.

Geometry and clamping that secure repeatable accuracy

The rhombic plate form with a nominal 35° approach angle and 5° relief provides a balanced mix of access and support for external and internal turning operations. A 0.8 mm corner radius offers a compromise between surface finish and edge robustness: the radius is large enough to protect the edge under intermittent cuts while still allowing fine surface quality. The plate is produced to ISO dimensions so that compatibility with external holders is ensured by matching form, relief angle, tolerance class, fastening type, overall size and thickness, giving repeatable seating and stable clamping when used with the appropriate holder.

Shop‑floor advantages and application guidance

The insert’s chipbreaker PS is optimised for medium cutting depths and variable feeds, promoting stable chip control in many stainless‑steel grades and reducing machining interruptions. A 3.18 mm plate thickness and the cylindrical hole with single‑side countersink (40°–60°) ensure secure fastening and straightforward replacement during setup. For operations requiring a balance of productivity and finish, the combination of PVD surface hardness and the chosen tungsten‑carbide substrate reduces flank wear and supports predictable tool life, which benefits throughput and process planning on mixed production runs.

FAQ

What materials is this insert intended for?
The VBMT 110308 AH6225 insert is optimised for stainless‑steel machining; the PVD‑coated carbide substrate supports medium‑duty turning of corrosion‑resistant alloys.

Which chip shape can be expected with the PS chipbreaker?
The PS chipbreaker promotes shorter, controlled chips in medium feeds and depths, improving evacuation and reducing the risk of entanglement during turning.

How does the 0.8 mm corner radius affect surface finish and tool life?
A 0.8 mm corner radius increases edge strength and wear resistance while still allowing a good surface finish in most medium‑cutting scenarios.

Is this insert compatible with standard ISO holders?
Yes, as an ISO‑standard rhombic insert, compatibility depends on matching form, relief angle, tolerance class, fastening and plate thickness; select a holder that corresponds to these parameters.

What fastening features does the insert have for secure clamping?
The insert includes a cylindrical hole with a single‑side countersink (40°–60°) to ensure robust clamping and repeatable seating in appropriate holders.
