VBMT160408-PSS T9225 indexable turning insert — 35° rhombic form, CVD‑coated, Tungaloy

The VBMT160408-PSS T9225 is an ISO‑standard indexable turning insert designed for medium to heavy steel turning, offering a robust CVD‑coated cemented carbide grade and a PSS chipbreaker for reliable chip control.

• CVD‑coated cemented carbide T9225
• ISO‑standard VBMT 160408 form
• 0.8 mm corner radius for rugged edge
• Suited to medium to heavy steel turning

Reliable metal removal for variable cutting conditions

The combination of a CVD‑coated cemented carbide substrate and the T9225 grade delivers a balance of hardness and toughness that is particularly useful in medium to heavy steel turning where cuts can be slightly interrupted or engagement conditions change. The coating supports thermal resistance and wear protection, while the substrate provides required fracture resistance; together they help to maintain cutting edge integrity and reduce the frequency of index changes. This results in steadier cycle times and a more predictable tool life in batch production and single‑piece runs alike.

Geometry engineered for consistent chip control and surface quality

The rhombic 35° approach angle and 5° clearance angle combine to produce a favourable cutting geometry for external and internal turning operations, promoting smooth engagement and efficient shear. The PSS chipbreaker is engineered to control chip form and evacuation, lowering the risk of entanglement and improving surface finish. The 0.8 mm corner radius supports robustness at the edge, reducing the likelihood of premature chipping during interrupted cuts while still enabling acceptable dimensional control on turned profiles.

ISO compatibility and secure clamping reduce setup time

As an ISO‑standard insert, the VBMT160408‑PSS form ensures compatibility with a wide range of external holders and boring bars; matching is determined by shape, clearance angle, tolerance class, fixing method, size and thickness. The insert’s cylindrical hole with single‑sided countersink (40°–60°) provides positive location and reliable clamping when assembled with the appropriate shim or clamping set and replacement screws. This predictable fitment simplifies tool inventory management and shortens setup and changeover intervals on the shop floor.

Production benefits that support efficiency and repeatability

Using a grade optimised for tougher engagement conditions, such as T9225, helps to extend cutting performance under mixed loads and intermittent cutting, which can translate into lower tooling costs per part and fewer interruptions for tool changes. The insert’s design supports repeatable results and consistent surface quality across batches, contributing to higher process reliability and reduced rework. For operations prioritising uptime and dependable finishing, the combination of geometry and material composition supports both throughput and part quality — a solid choice for conventional and semi‑automated turning centres.

FAQ

Is this insert suitable for interrupted cuts and variable engagement?
The Tungaloy VBMT160408‑PSS T9225 insert is formulated for robustness in medium to heavy steel turning and performs reliably under slightly interrupted cuts and changing engagement conditions.

Which workpiece materials is this grade recommended for?
The T9225 grade is intended primarily for steel machining, providing a good balance of wear resistance and toughness for a wide steel material range.

How does the PSS chipbreaker help in production?
The PSS chipbreaker shapes and controls chips to assist evacuation and reduce chip re‑entanglement, which improves process stability and surface finish when using the insert.

What information is needed to ensure holder compatibility?
Compatibility depends on the insert form (VBMT 160408), clearance angle (5°), tolerance class, fixing method, size (16 mm) and plate thickness (4.76 mm); matching holders or boring bars that accept VBMT‑form inserts are required
