TUNGALOY VBMT160408PS-AH120 35° Rhombic Carbide Insert with PS Finishing Chipbreaker and AH120 PVD Coating for CNC Turning

The TUNGALOY VBMT160408PS-AH120 is a high-precision 35° rhombic (V-type) solid carbide turning insert with 5° positive relief angle, designed for finishing to light-medium turning of steels, stainless steels, and cast irons. Equipped with Tungaloy’s versatile PS finishing chipbreaker and balanced AH120 PVD (Ti,Al)N coating grade, it delivers low cutting forces, superior surface finish, and reliable chip control in continuous to light interrupted cuts. Ideal for precision components, automotive parts, and general engineering, it ensures stable, long tool life in mixed production environmentsTungaloy.

• 35° Rhombic (V-type) Geometry: 5° positive relief angle, sharp cutting edge, ideal for intricate profiling and finishing with minimal friction.
• PS Chipbreaker (Finishing): Large edge inclination + precision groove design; optimizes chip flow in light depths of cut (0.5–2.5mm), prevents built-up edge and crater wearTungaloy.
• AH120 Grade: “Flash Coating” (Ti,Al)N PVD coating; balanced wear and fracture resistance, excellent oxidation stability (up to 900°C), suitable for broad material ranges.
• Precision Cutting Edge: Ground 0.8mm corner radius (R0.8) and sharp honed edge for high dimensional accuracy and mirror surface finish.
• Positive Rake Design: Reduces cutting forces by 15–20%, ideal for low-power CNC machines and thin-wall components.
• Ultra-Fine Carbide Substrate: High hardness with good toughness, resists chipping in light interrupted cuts and profiling.

• Carbon steels (1045, S355, Q235)
• Alloy steels (4140, 4340, 42CrMo4)
• Stainless steels (304, 316, 420, duplex)
• Cast irons (gray, ductile)
• Non-ferrous metals (aluminum alloys, copper)

• External finishing & light-medium turning
• Precision profiling and contouring
• Boring and internal finishing
• Facing and chamfering
• Automotive precision parts (shafts, pins)
• Medical components and hydraulic parts

As Tungaloy’s first choice for general-purpose finishing, the AH120 grade with PS chipbreaker outperforms conventional inserts in surface finish (Ra ≤ 0.8μm), low cutting forces, and versatility. The (Ti,Al)N coating provides excellent adhesion and thermal stability, while the positive geometry minimizes workpiece deformation. It reduces downtime for finishing operations and ensures consistent quality in mixed batches, making it the cost-effective solution for precision CNC turningTungaloy
