CNMG 160612 T9235 turning insert — CVD-coated carbide, double-sided chipbreaker | Tungaloy

The CNMG160612 T9235 is an ISO-standard turning insert engineered for both external and internal turning, offering a tough, CVD-coated carbide grade for interrupted cuts and unstable machining conditions.

• ISO-standard CNMG geometry
• CVD-coated carbide grade T9235
• Tough grade for unstable and interrupted cuts
• Double-sided chipbreaker with cylindrical hole

Proven toughness for interrupted and unstable turning

The indexable insert combines a CVD-coated surface with a tough carbide substrate to provide controlled wear under demanding conditions. This composition makes the insert especially suited to machining steel where cutting speeds are moderate and the cut is interrupted or unstable. The T9235 grade is formulated to resist chipping and maintain cutting edge integrity, which translates into steadier component quality and reduced tool-change frequency. The combination of coating and substrate also supports predictable tool-life behaviour, aiding process planning in production environments.

Precise geometry for dependable clamping and repeatability

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening, size and thickness, all conforming to ISO standards. With an inscribed size of 16 mm, a thickness of 6.35 mm and a corner radius of 1.2 mm, the insert provides consistent seating and repeatable positioning in commercial CNMG-compatible holders. The 0° clearance angle and 80° included angle help define the effective engagement and cutting forces, so correct holder selection and secure clamping yield stable cutting conditions and reproducible surface finish without guesswork.

Chip control and edge utilisation to boost productivity

The double-sided chipbreaker design, combined with a cylindrical hole for positive location, supports controlled chip formation and evacuation even under irregular cut interruptions. Good chip control reduces rework and risk of built-up edge, improving cycle reliability on both external and internal features. The rhombic insert form and indexable nature enable multiple edge uses per insert, lowering per-part tooling cost and simplifying inventory management in the workshop.

Practical selection and application guidance

For best results, pair the insert with a matching external holder or boring bar, and choose the chipbreaker style and grade according to workpiece material, machining method and machine stability. The ISO-series system architecture—insert, holder, shim/clamp set and replacement screws—ensures each component is specified for a coherent setup. In marginally stable setups the T9235 grade is recommended at reduced cutting speeds to preserve edge life; in steady, high-speed scenarios a different grade may be preferable to increase metal removal rate.

FAQ

What makes this insert suitable for interrupted cuts?
The CVD-coated T9235 grade and tough carbide substrate provide resistance to chipping and edge fracture, making the CNMG160612 T9235 insert appropriate for interrupted and unstable cutting conditions.

Which holders are compatible with this CNMG geometry?
Compatibility depends on matching form, clearance angle, tolerance class, fastening, size and thickness; when these parameters align, standard CNMG holders and boring bars accept the CNMG160612 insert.

What are the key dimensions to check before ordering?
Check the inscribed size (16 mm), thickness (6.35 mm) and corner radius (1.2 mm); these determine seating, corner engagement and the achievable contour radius in turning operations.

Does the double-sided chipbreaker improve chip control?
Yes, the double-sided chipbreaker combined with the cylindrical locating hole encourages stable chip formation and evacuation, supporting cleaner cuts and less risk of built-up edge.

Is this insert suitable for stainless or special alloys?
The CNMG160612 T9235 insert is a tough grade optimised for steel and interrupted cuts; for stainless steel or advanced alloys, consult application data to confirm the ideal grade and cutting parameters.
