VNMG 160412 T5125 VNMG turning insert for turning — Tungaloy

The VNMG160412 T5125 is an ISO-standard indexable turning insert designed for external and internal turning, optimised for cast iron and interrupted-cut conditions.

• CVD-coated carbide grade T5125
• Optimised for cast iron and interrupted cuts
• ISO VNMG 160412 rhombic 35° geometry
• Double-sided insert with cylindrical hole

Reliable chip control and prolonged tool life for cast iron

The CVD-coated substrate combined with the T5125 grade delivers a balance of toughness and wear resistance that is particularly suited to machining cast iron under unstable conditions. The double-sided chipbreaker promotes predictable chip flow and reduces the risk of chip clogging, while the 1.2 mm corner radius increases edge strength for interrupted cuts. These design choices reduce unscheduled stoppages and contribute to a more consistent surface finish, thereby improving process reliability and overall productivity.

Quick integration into ISO-compatible turning systems

Conformity to the ISO VNMG 160412 form ensures straightforward compatibility with standard clamping systems. Compatibility is determined by form, clearance, tolerance class, fastening method, size and thickness; the insert’s rhombic 35° geometry and 0° clearance angle allow selection of suitable external or internal holders with minimal adaptation. The insert is supplied as a system element: indexable insert, matching holder or boring bar, shim/clamping set and replacement screws are recommended to complete the toolset and secure repeatable torque and positioning.

Stable performance in interrupted cutting and less rigid set-ups

The material combination of a tough carbide substrate and CVD coating is engineered to withstand shock loading typical for interrupted cuts. This results in fewer edge chipping events and a predictable wear pattern, which supports longer in-service intervals and lower tooling costs per part. The insert’s design absorbs transient forces, which is an advantage when machining components on less rigid machines or when facing variable clamping conditions.

Selection guidance to match process requirements

Choose the chipbreaker and the T5125 grade in line with the workpiece material, machining strategy and machine rigidity; for external and internal turning, select holders that match the insert’s 4.76 mm thickness and 16 mm size to maintain correct seat geometry. The cylindrical hole provides consistent clamping and indexability for double-sided use, increasing effective cutting-edge count. Where higher finish is required, consider the edge radius implications: the 1.2 mm radius enhances strength but yields a recognisable influence on surface roughness versus smaller radii.

FAQ

What materials is this insert best suited to?
The VNMG160412 T5125 insert is particularly suited to cast iron machining; the T5125 grade and CVD coating provide toughness and wear resistance for interrupted cuts.

Can this insert be used for both external and internal turning?
Yes, the rhombic VNMG form and ISO conformity allow use in both external holders and suitable boring bars for internal turning.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm corner radius increases edge strength and improves durability under interrupted cutting, with a trade-off towards a slightly higher minimum surface roughness compared with finer radii.
