VBMT160408-PS AH725 ISO turning insert — PVD-coated carbide, PS chipbreaker — Tungaloy

The VBMT160408-PS AH725 is a rhombic ISO turning insert for external and internal turning, engineered for stable chip formation and high process security in mixed-material production.

• PVD-coated carbide AH725 grade
• PS chipbreaker for stable chip control
• 0.8 mm corner radius for precise turning

Consistent process stability for demanding turning tasks

The combination of a PVD coating and a wear-resistant carbide substrate provides elevated process reliability under varying cutting conditions. The grade AH725 is formulated to reduce flank wear and preserve a stable cutting edge, which translates into longer tool life and fewer interruptions on the production floor. With the PS chipbreaker integrated, chip formation is controlled even in interrupted cuts and variable feeds, lowering the risk of surface blemishes and tool damage while improving productivity and machine uptime.

One grade for multiple materials — efficiency and adaptability

Designed as a universal, breakout-resistant option, the AH725 grade suits machining of steel and stainless steel, making it appropriate where material batches vary or tool inventories must be streamlined. The insert’s geometry and chipbreaker selection favour smaller tooling assemblies and operations with high demands on reproducible results. The outcome is simplified tool planning, reduced changeover time and a consistent surface finish when switching between common workshop alloys and stainless steel variants.

ISO conformity and secure mounting for dependable integration

The insert follows ISO geometry standards as a rhombic plate in size 16 with a 4.76 mm plate thickness, a 5° clearance (freespace) angle and a 35° wedge configuration, ensuring compatibility with standard holders when form, tolerance class, fastening and thickness match. The centre is supplied with hole featuring a cylindrical bore and a single-sided countersink (40°–60°), enabling secure clamping and simple indexability. These dimensional details support predictable clamping forces and repeatable positioning, which together reduce setup variance and increase process repeatability in batch production.
