VBMT 160412 AH725 — VBMT Turning Insert (PSS chipbreaker) by Tungaloy

VBMT 160412 AH725 is an ISO-format indexable turning insert for general-purpose external and internal turning in mixed-material production environments

• ISO-format VBMT geometry
• PVD-coated carbide AH725
• PSS chipbreaker for reliable chip control
• Rhombic 35° shape, corner radius 1.2 mm

Stable chip control that protects cycle time

The combination of the PSS chipbreaker and a PVD-coated carbide substrate delivers consistent chip formation under varying cutting conditions. This design reduces the frequency of tool stoppages caused by poor chip evacuation and minimises the risk of built-up edge on stainless steels. The chipbreaker is tuned for both short and medium chip forms, which supports longer uninterrupted runs and contributes directly to improved overall equipment effectiveness.

Universal grade AH725 for mixed-material production

The AH725 grade is a universal, fracture-resistant coating solution developed for reliable machining of steels and stainless steels. Its balanced substrate and coating properties provide a good compromise between wear resistance and edge toughness, making it suitable where batch production includes different materials. This increases process security in setups with changing workpiece alloys and smaller tooling, reducing the need for frequent insert changes.

ISO conformity and holder compatibility explained

As an ISO-standardised insert, dimensional and tolerance conformity is the basis for predictable seating in holders. Compatibility depends on the insert form, clearance angle 5°, tolerance class, fixation method, size and thickness; correct matching to the corresponding external holder or boring bar is essential for repeatable results. The rhombic format with a 35° included angle provides favourable approach angles for both finishing and light roughing operations.

Practical geometry and features that aid setup

Key geometry features such as corner radius 1.2 mm, thickness 4.76 mm, and an inscribed circle of 16 mm make the insert versatile for a wide range of turning tasks. The centre hole with a cylindrical bore and a single-sided countersink (40°–60°) enables secure clamping and easy indexing. Such features reduce setup time, ensure secure seating under interrupted cuts, and contribute to consistent surface finish and dimensional control.

FAQ

What materials is this insert suitable for? The VBMT 160412 AH725 by Tungaloy is designed primarily for steels and stainless steels and performs well across mixed-material production due to its universal AH725 grade.

How does the PSS chipbreaker affect machining? The PSS chipbreaker on this indexable insert promotes controlled chip formation and evacuation, which helps to maintain cycle times and reduce the likelihood of chip-related interruptions during turning.

Is the insert compatible with standard VBMT holders? Compatibility is ensured when the holder matches the ISO geometry, clearance angle, tolerance class, fixation method, size and thickness; the VBMT format is ISO-standard so matching holders with the same VBMT specification will be required.

What advantages does the 1.2 mm corner radius provide? A corner radius of 1.2 mm offers a compromise between edge strength and surface finish, improving tool robustness on interrupted cuts while delivering acceptable surface quality in finishing passes.

How is the insert secured in the tool? This insert includes a centre hole with a cylindrical bore and a single-sided countersink; when used with the correct clamping kit and screw set it achieves reliable seating and repeatable indexing.
