VNMG 120404 AH8015 – ISO turning insert VNMG120404E-PS, PVD-coated carbide, for turning – Tungaloy

The VNMG120404E-PS AH8015 is an ISO‑standard rhombic turning insert, PVD‑coated carbide, engineered for reliable external and internal turning of heat‑resistant alloys.

• PVD‑coated AH8015 grade
• PS chipbreaker for controlled chips
• 0.4 mm corner radius for robust edges
• ISO VNMG 120404 rhombic form

Consistent machining with a balanced carbide grade

The PVD‑coated AH8015 offers a measured combination of wear resistance and edge stability, making it a first choice for general machining of heat‑resistant alloys. The applied coating increases thermal and abrasive resistance without compromising the cutting edge, so the indexable insert sustains longer productive cuts and fewer tool changes. This balance reduces process interruptions and supports predictable component quality when the material mix or machining cycles demand dependable performance.

Precision geometry that improves tool life and component quality

Designed in the ISO VNMG geometry, the insert features a 0.4 mm corner radius and a 35° lead angle, with a relief (clearance) angle of 0°. The corner radius strengthens the cutting edge and helps distribute cutting forces, while the rhombic shape allows versatile approach angles for both external and internal turning. Compatibility with the holder is governed by form, relief angle, tolerance class, fixing method, size and thickness, so matching insert and holder ensures repeatable clamping and maximises tool life.

Controlled chips and smooth process integration

The PS chipbreaker is engineered for stable chip formation across a range of feed rates typical for ISO turning operations. The insert’s cylindrical hole facilitates reliable clamping and quick indexability in standard holders or boring bars. When fitted into a correctly specified tool system — ISO turning plate, matching external holder or boring bar, plus clamp set and retaining screws — the componentry reduces vibration, improves surface finish and lowers the risk of built‑up edge. This system approach supports higher uptime and more consistent part output.

Practical application tips for turning operations

Intended primarily for turning, the insert performs best when paired with a holder that matches its form, size and thickness; the plate thickness of 4.76 mm and plate size 12 mm are standard dimensions to check during tool selection. Select the AH8015 grade and PS chipbreaker when machining tough, heat‑resistant alloys where a compromise between wear resistance and edge strength is required. For customers new to the grade or changing workpiece materials, a short trial under representative conditions will quickly demonstrate the improved stability and surface quality.

FAQ

What materials is this insert best suited for? The VNMG120404E-PS AH8015 is optimised for heat‑resistant alloys; the AH8015 grade balances wear resistance and edge stability for such materials.

How does the PS chipbreaker affect machining? The PS chipbreaker provides controlled chip formation and reduces the risk of long, stringy chips, improving process reliability when using the Tungaloy insert in ISO turning operations.

Which holders are compatible with this insert? Compatibility depends on holder form, relief angle, tolerance class, fixing and plate size; use a holder specified for VNMG 120404 inserts with a cylindrical‑hole clamping system.

What does the 0.4 mm corner radius mean for part quality? A 0.4 mm corner radius increases edge strength and helps produce a more robust surface finish, reducing the likelihood of edge chipping during interrupted cuts.

Is this insert indexable and replaceable during production? Yes, the insert is indexable; the ISO plate design allows rotation or replacement in the holder to restore cutting performance without changing the entire tool body.
