VBMT110308-PS AH120 ISO turning insert, PVD-coated carbide, PS chipbreaker — Tungaloy

A VBMT110308-PS AH120 insert for precision external and internal turning, offering process-stable cutting with a PVD-coated carbide grade and a PS chipbreaker.

• ISO rhombic insert VBMT110308 format
• PVD-coated AH120 carbide for wear resistance
• PS chipbreaker for consistent chip control
• Cylindrical hole with 40°–60° one-side countersink

Stable cutting and predictable chip control

The combination of a PVD-coated surface and the AH120 carbide grade yields a balanced performance that prioritises process stability and consistent tool life. The integrated PS chipbreaker is engineered to form short, controllable chips under a wide range of cutting conditions; this reduces the risk of entanglement and enhances machine uptime. In practice, the chipbreaker geometry helps to direct chips away from the cutting zone and to maintain a stable cutting force, which is particularly valuable when switching between external and internal turning operations.

Longer tool life through edge integrity and coating technology

A sharp, durable cutting edge is essential for repeatable results. The carbide substrate combined with a PVD coating reduces flank wear and improves resistance to abrasive and adhesive wear mechanisms, which results in fewer insert changes and more consistent surface finish. Where process security and a well-defined cutting edge are required, this insert offers measurable benefits: extended service intervals and reduced secondary operations. The material selection and coating technology together contribute to reliable component tolerances over serial production runs.

Clear mounting guidance and application suitability

Built to ISO dimensions and a rhombic plate form, the insert fits established insert holders when the form, 5° clearance angle, tolerance class, fixing method, size and thickness match the holder specification. Key geometry values such as the 0.8 mm corner radius, 3.18 mm thickness and 35° lead angle influence cutting behaviour; the plate’s cylindrical hole with a one-side countersink (40°–60°) ensures secure clamping and positional accuracy. The system is completed by a compatible external holder or boring bar, a shim and the correct clamping screw; select the chipbreaker and grade to suit the workpiece material and machining stability for best results.

FAQ

What materials is this insert suitable for?
The VBMT110308-PS AH120 is designed as a wear- and chipping-resistant grade for general turning; the AH120 PVD-coated carbide performs well across a broad spread of materials when the correct chipbreaker and machining parameters are chosen.

How does the PS chipbreaker affect machining?
The PS chipbreaker on the VBMT110308-PS AH120 shapes chips into short, controllable segments, improving chip evacuation and contributing to process reliability during repetitive turning operations.

Which holders are compatible with this insert?
Compatibility depends on holder form, free angle, tolerance class, fixing method, size and thickness; the VBMT110308-PS follows ISO geometry, so matching ISO holders and the correct clamping components are required for secure mounting.

What are the key geometry values to consider when selecting this insert?
Important values are the 0.8 mm corner radius, 3.18 mm plate thickness, 11 mm inscribed circle and the 5° clearance angle and 35° lead angle; these influence cutting forces, surface finish and tool engagement.

Is the insert supplied with screws or shims?
The product listing refers to the insert itself; the complete system comprises the insert, a suitable holder, shim and clamping screws, which should be selected or ordered according to the machine setup.
