Order the insert directly via Metav Werkzeuge or contact our consultants for application advice. CNMG 120412 T9235 Turning indexable insert by Tungaloy — CVD-coated carbide, 1.2 mm corner radius The CNMG120412 T9235 is an ISO‑standard turning insert designed for external and internal turning applications where interrupted cuts or unstable setups demand a tough, damage-resistant grade. ISO CNMG 120412 format for standard holders CVD-coated carbide grade T9235 for steel 1.2 mm corner radius for robust edge strength Double-sided chipbreaker with cylindrical hole Consistent cutting under unstable conditions The insert’s CVD-coated carbide grade T9235 is formulated to deliver toughness rather than maximum hardness, making it suitable for steel machining at moderate cutting speeds and where interrupted cuts occur. The coating improves wear resistance and helps maintain a stable cutting edge during variable engagement. For production environments with occasional chatter or varying clamping stiffness, this composition reduces the risk of premature edge chipping and supports repeatable component quality. Fast changeover and secure clamping for increased uptime As an ISO CNMG 120412 format, the indexable insert fits a wide range of standard external holders. Compatibility is governed by the insert’s shape, clearance angle, tolerance class, fastening method, size and thickness — the defined geometry allows predictable seating and repeatable positioning. The cylindrical hole and matching clamp hardware provide a secure mounting interface, so tool changes are rapid and downtimes are minimised, contributing to a more efficient workflow on the shop floor. Edge geometry engineered for productivity and chip control A 1.2 mm corner radius offers a compromise between edge strength and finishing capability: it increases robustness for roughing passes while still permitting acceptable surface quality on many turning operations. The double-sided chipbreaker provides two usable cutting edges per side, effectively extending tool life and lowering cost per edge. The 4.76 mm plate thickness contributes to insert rigidity, reducing vibration sensitivity and enabling steadier cutting forces for consistent dimensional results. Practical guidance for application and selection Select the CNMG120412 T9235 when machining unalloyed or low‑alloy steels under less-than-ideal stability or where interrupted cutting is expected. Match the chipbreaker and grade to the workpiece material and cutting conditions: a tougher grade at lower cutting speeds often outperforms harder grades in terms of reliability under shock loads. When in doubt, consult the insert’s system composition — holder, shim and clamping set — to ensure optimal force transmission and edge support.

CNMG 120412 TH10 Wendeplatten - Tungaloy
Combining the low cutting forces of the TH10 uncoated carbide grade with the secure clamping of the cylindrical-holed, rhombic geometry, this insert promotes consistent surface quality and efficient turning cycles. Order directly via Metav Werkzeuge or consult our specialists for tailored application advice. CNMG120412 TH10 ISO rhombic turning insert for turning applications, Tungaloy The CNMG120412 TH10 is an ISO rhombic turning insert intended for external and internal turning, offering a sharp universal grade suited to non-ferrous materials and applications requiring clean surfaces. ISO rhombic insert CNMG 80° geometry TH10 uncoated carbide for low cutting forces Cylindrical hole for secure clamping Double-sided chipbreaker, corner radius 1.2 mm Higher productivity with the sharp TH10 grade The TH10 grade is an uncoated, sharp universal carbide designed to reduce cutting forces and support cleaner part surfaces when machining non-ferrous materials. By lowering cutting resistance, the grade contributes to reduced tool-induced vibration and more consistent chip formation, which in turn helps maintain cycle times and improves repeatability in production environments. For workshops seeking reliable performance in light-to-medium stability set-ups, this characteristic makes the insert particularly effective at delivering stable feeds and improved surface integrity on aluminium alloys, brass and similar materials. The result is an efficient process that balances cutting efficiency with achievable surface quality. Secure clamping and ISO compatibility for repeatable results The insert’s geometry — a rhombic CNMG form with an 80° included angle and a cylindrical hole — ensures dependable mounting in standard external holders and boring bars. Compatibility with a given holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters guarantees correct seating and repeatable tool overhang and orientation. The ISO standard designation simplifies procurement and replacement in production lines, while the rhombic shape provides flexibility for both facing and general turning tasks. This combination supports predictable cutting conditions and reduces set-up variability across batches. Design features that support chip control and finish Built with a double-sided chipbreaker and a corner radius 1.2 mm, the insert assists in producing controlled chip forms and improved part faces during turning. The chipbreaker is tailored to promote short, manageable chips at typical feeds for non-ferrous materials, lowering the likelihood of entanglement and easing post-process handling. The corner radius balances edge strength and surface finish: a 1.2 mm radius provides a robust cutting edge while helping to achieve consistent surface appearance at standard finishing feeds. Together these attributes reduce process interruptions and support higher first-pass yield rates. System setup and practical guidance for turning operations The CNMG insert should be used as part of a system comprising the ISO insert, a matching external holder or boring bar, an underlay/clamping set and replacement screws. Choose the chipbreaker and grade according to workpiece material, machining strategy and machine stability; for non-ferrous and delicate operations the uncoated sharp grade proves advantageous due to lower adhesion tendency and cleaner surfaces.

Why indexable inserts are indispensable in modern machining
Indexable inserts, also known as cutting inserts or indexable cutting inserts, are standardised, replaceable cutting elements that mount on tool holders such as turning bits, milling cutters or drills. Made from wear-resistant materials like carbide, cermet, ceramic or other superhard grades, they carry the actual cutting edge and allow a worn corner to be rotated or flipped instead of replacing or regrinding the entire tool body.
How these inserts work and when to choose them
In everyday workshop and production settings, indexable inserts perform the direct material removal on the workpiece. Standard inserts for tool systems without internal coolant typically feature closed faces or a single central fixing hole, with heat evacuation handled by external machine nozzles. Inserts designed for systems with internal coolant are engineered to support coolant flow: they include calculated chipbreaker geometries that guide an internal coolant jet under the chip or, in specialised designs, contain sintered microchannels to direct coolant right to the cutting edge. Such coolant-compatible inserts are essential for machining heat-resistant alloys, heavy cutting operations and deep internal machining, where thermal load and chip control are critical.
Tangible benefits for production and workshop efficiency
Choosing the right indexable inserts delivers measurable operational advantages:
- Reduced downtime: faster changeover because a worn insert is simply indexed rather than the whole tool being replaced.
- Extended cutting-edge life: targeted coolant application and optimised chipbreaker design lower thermal stress and improve tool life.
- Consistent part quality: predictable cutting-edge geometry from standardised inserts maintains tolerances across batches.
- Versatility: availability in carbide, cermet, ceramic and superhard grades permits selection according to workpiece material and cutting conditions.
- Lower tooling costs over time: fewer full-tool replacements and less regrinding required.

FAQ
What materials are indexable inserts available in?
Indexable inserts are available in wear-resistant grades such as carbide, cermet, ceramic and other superhard materials, selected according to the workpiece material and cutting conditions.
When should I choose inserts with internal coolant support?
Choose inserts designed for internal coolant when machining heat-resistant alloys, performing heavy cuts or working in deep internal features, because the coolant reduces thermal load at the cutting edge and actively improves chip breakage.
How do chipbreaker geometries affect performance?
Chipbreaker geometries on indexable inserts guide the chip flow and, when matched to an internal coolant jet, direct the coolant under the chip to control temperature and facilitate reliable chip formation, which extends edge life and stabilises machining.
Can standard inserts be used with external coolant only?
Yes; standard inserts for tool systems without internal coolant typically have closed faces or a central fixing hole and rely on external machine nozzles for heat evacuation, which is sufficient for many routine, accessible cuts.
Why source inserts through Metav?
