VNMG160412 160412 T5125 VNMG indexable insert for turning — Tungaloy

VNMG160412 T5125 Tungaloy indexable insert for ISO-compliant turning applications, optimised for interrupted cuts and less-stable machining conditions

• CVD-coated grade T5125 for cast iron
• Designed for interrupted cuts and instability
• Rhombic 35° geometry for stable engagement
• 1.2 mm corner radius with cylindrical hole

Durable grade for challenging cast-iron work

The CVD-coated carbide grade T5125 delivers a tougher substrate that resists chipping under interrupted cutting conditions. That increased toughness translates into fewer insert failures and more predictable machining cycles when working with cast iron, even where vibration or less rigid set-ups are a factor. The specification of a dedicated machining grade means the insert supports steady productivity and reduces the risk of scrap parts from sudden edge breakouts.

Stable geometry and exact fit for repeatable results

ISO conformity simplifies tool selection: the insert’s rhombic geometry and 35° cutting angle produce a secure cutting engagement that supports consistent surface finish and dimensional control. The format includes a cylindrical hole for positive clamping and a 0° relief angle, while the 16 mm inscribed size and 1.2 mm corner radius ensure predictable edge strength. Compatibility with holders is determined by form, relief angle, tolerance class, clamping method, size and thickness; matching these parameters avoids runout and facilitates quick, repeatable tool changes.

Practical economy through chip control and uptime

The double-sided chipbreaker layout offers economical use of each indexable face and improved chip formation across a range of cutting conditions. By combining a robust substrate with a dedicated chip control geometry, the insert supports longer effective tool life and reduced downtime for index changes. For production environments, the result is increased throughput and lower cost per part without compromising process stability.

System considerations and typical applications

The insert is intended for external and internal turning within an ISO-based system: an appropriate external holder or boring bar, an underlay/clamping kit and replacement screws form the complete set-up. The grade’s emphasis on interrupted cuts and less-stable conditions means the part is particularly suited to cast-iron components or operations where suboptimal rigidity is expected. For routine planning, specify the chipbreaker and grade to match the workpiece material, machining strategy and machine stability to obtain the best balance of performance and economy.

FAQ

Is this insert suitable for cast-iron machining?
Yes. The VNMG160412 T5125 indexable insert is a CVD-coated carbide grade developed for cast-iron applications, especially where interrupted cuts or less stable conditions occur.

How is compatibility with holders determined?
Compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness; the VNMG160412 has a 16 mm inscribed size, 4.76 mm thickness and 0° relief angle and requires an ISO-compatible holder with matching specifications.

What advantages does the T5125 grade provide?
Grade T5125 offers enhanced toughness and wear resistance, improving resistance to chipping during interrupted cutting and contributing to longer, more reliable tool life for demanding turning operations.

What is the function of the double-sided chipbreaker?
The double-sided chipbreaker provides controlled chip formation across different cutting conditions and allows economical use of both cutting edges before indexing, reducing downtime and consumable costs.

Which accessories complete the tool system for this insert?
A suitable external holder or boring bar, an underlay/clamping kit and replacement screws form the complete ISO-based system for safe and repeatable operation with this insert.
