CNMG160612 T9235 — Indexable turning insert, ISO-standard, for turning (Tungaloy)

CNMG160612 T9235 is an ISO-standard indexable turning insert developed for external and internal turning where interrupted cuts or unstable conditions occur; the geometry and grade are optimised for steel applications.

• CVD-coated carbide grade T9235
• For steel, low cutting speeds and interrupted cuts
• Rhombic CNMG 80° geometry, 1.2 mm corner radius
• Double-sided chipbreaker, cylindrical hole design

Reliable cutting performance where stability is limited

The CNMG160612 T9235 insert combines a CVD-coated surface with a tough carbide substrate to withstand impacts and fluctuating cutting forces. This ISO-standard insert is engineered for turning operations that require secure edge behaviour in stop-and-go or interrupted machining. The combination of coating and substrate reduces flank wear and helps maintain dimensional accuracy in serial and job-shop production, offering a tangible productivity advantage when feeds and speeds cannot be fully stabilised.

Clear compatibility criteria and practical clamping guidance

Compatibility with toolholders depends on form, clearance, tolerance class, fastening method, size and thickness; the rhombic plate format and the presence of a cylindrical hole simplify positive location in many standard CNMG holders. The insert features a 0° clearance setting and an 80° included angle, which should be matched to a holder that accepts ISO CNMG plates and secures them to prevent movement under interrupted loads. Choosing a holder with the correct seating and screw configuration ensures repeatable clamping and reduces the risk of edge chipping.

Better chip control and economical cutting cycles

The double-sided chipbreaker provides controlled chip formation on both indexable faces, improving evacuation in turning operations and reducing rework. With a 1.2 mm corner radius, the insert balances edge strength and surface finish, enabling more robust passes without sacrificing workpiece quality. These attributes translate into longer edge life and fewer index changes, supporting a more efficient production flow and lower tool handling times.

Material focus and recommended cutting strategies

This grade is specified as T9235, a CVD-coated carbide designed for steel machining at moderate to lower cutting speeds and in conditions where cuts are frequently interrupted. For roughing under unstable setups, select conservative speeds and feeds to exploit the insert's toughness; for finishing, optimise feed for the required surface quality while retaining the insert’s edge integrity. For specific holder pairings or cutting-parameter recommendations, Metav Werkzeuge can advise on matching carriers and insert orientations to achieve consistent results.

FAQ

What materials is this insert designed for?
The CNMG160612 T9235 insert is specified for machining steel; the T9235 grade is formulated to perform under lower cutting speeds and interrupted conditions common in steel turning.

How is compatibility with toolholders ensured?
Compatibility is determined by plate form, clearance angle, tolerance class, fastening, size and thickness; the CNMG geometry and cylindrical hole accommodate standard CNMG holders when the holder accepts ISO CNMG plates.

What chip control features are provided?
The double-sided chipbreaker on the CNMG160612 T9235 supports controlled chip formation on both faces, improving evacuation and reducing risk of re-cutting in turning operations.

What is the corner radius and what does it mean for machining?
The insert has a 1.2 mm corner radius, which offers greater edge strength for roughing and interrupted cuts while still enabling acceptable surface quality for many finishing passes.

Does this insert have a hole, and what type is it?
Yes, the insert is supplied with a cylindrical hole for positive location and secure clamping in compatible holders.
