VBMT 160408 AH6235 ISO turning insert for turning, rhombic geometry — Tungaloy

VBMT160408-PS AH6235 is an ISO‑standard turning insert designed for general turning and for demanding work on stainless and high‑toughness materials.

• PVD-coated carbide grade AH6235
• Optimised for stainless steel and interrupted cuts
• Rhombic VBMT shape with 35° lead angle
• Cylindrical hole with single‑side countersink

Stable cutting performance for stainless and demanding materials

The PVD-coated AH6235 grade is formulated as a tougher carbide for machining stainless steels and operations with frequent interruptions or elevated breakout risk. The tougher substrate reduces the tendency for chipping and edge failure, while the thin PVD layer improves wear resistance and adhesion control. This combination results in more consistent component quality and extended edge life, which supports higher production uptime and fewer insert changes. The design is particularly suited to faces and profiles where intermittent cuts or built‑up edge would otherwise limit tool life.

Geometry and clamping that enhance process security

The rhombic VBMT outline with a 35° lead angle and 5° relief angle offers a balanced compromise between chip flow and cutting force direction, making it suitable for both external and internal turning operations. A 0.8 mm corner radius delivers a predictable cutting edge radius that improves surface finish while maintaining strength at the tip. The insert is supplied with a cylindrical hole and a single‑side countersink (40°–60°) for positive clamping compatibility; this ensures repeatable seating in standard ISO‑compatible holders and reduces the risk of movement during heavy cuts. These geometry choices translate into stable machining and fewer rejected parts.

Process guidance and economical advantages

Selecting the correct chipbreaker and grade is critical: the PS chipbreaker here supports controlled chip formation on medium to tough stainless alloys, lowering spindle downtime due to chip entanglement. The insert’s 4.76 mm thickness and standard 16 mm size conform to common holder systems, simplifying stocking and reducing tooling complexity across multiple machines. From a cost‑efficiency perspective, the tougher grade reduces unexpected edge loss and the need for frequent index changes, making it a productive option for batch and series production where reliable tool life equals measurable savings.

FAQ

What materials is this insert best suited for?
The AH6235 grade is optimised for machining stainless steels and other tougher alloys; the insert's toughness helps resist chipping during interrupted cuts.

Which chipbreaker does the insert feature and what is its benefit?
The VBMT160408-PS is fitted with the PS chipbreaker, which promotes controlled chip formation on medium to highly ductile materials, improving evacuation and process reliability.

Is this insert compatible with standard ISO holders?
Yes — the rhombic geometry, ISO designation 160408 and the cylindrical hole with countersink are designed for compatibility with ISO‑compliant turning holders that match form, thickness and clamping style.

How does the 0.8 mm corner radius affect surface finish?
A 0.8 mm corner radius balances edge strength with surface finish: it reduces the risk of edge chipping while helping to achieve smoother component surfaces compared with very small radii.

What distinguishes the AH6235 grade from general-purpose grades?
AH6235 is a tougher PVD‑coated carbide grade formulated to withstand interrupted cuts and elevated breakout risk typical of stainless machining, providing longer edge life in challenging conditions.
