CNMA 190616 T5125 Wendeplatten - Tungaloy
Take advantage of the combination of CVD-coated carbide T5125, an 80° rhombic geometry and a 1.6 mm corner radius for reliable turning in interrupted or less stable conditions; these characteristics support stable chip formation and extended tool life. Order the CNMA190616 T5125 Tungaloy insert directly via Metav Werkzeuge or ask our consultants if needed. CNMA190616 T5125 — ISO turning insert CNMA 190616 T5125 for turning, Tungaloy A CNMA190616 T5125 indexable insert engineered for external and internal turning, especially where interrupted cuts or unstable set-ups demand a tougher, CVD-coated carbide grade. CVD-coated carbide grade T5125 Optimised for interrupted cuts 80° rhombic shape with 1.6 mm radius Precision and reliability for demanding turning operations The insert’s CVD-coated surface and T5125 grade deliver a balance of toughness and wear resistance that benefits components produced from brittle or variable materials. The substrate of carbide provides the hardness needed for sustained cutting, while the coating reduces flank wear and increases edge life. In practice, this results in fewer tool changes and steadier component quality when machining cast components or mixed-material batches. The geometry helps convert vibrations into controlled chip formation, so surface finish and process repeatability improve under interrupted cutting cycles. Seamless integration into ISO tool systems for efficient setup Designed to ISO dimensions, the plate fits holders determined by form, clearance and dimensional tolerances, reducing set-up time and inventory complexity. The 80° rhombic form with a 0° clearance angle and the standard size of 19 mm × 6.35 mm ensure compatibility with common external holders and boring bars. A cylindrical hole secures the insert reliably in the pocket and simplifies indexation. The net effect for production: faster changeovers, predictable clamping accuracy and lower risk of incorrect mounting. Robust choice where interrupted cuts or instability occur The tougher CVD-coated grade is specified for machining cast iron under interrupted cutting or less stable conditions; this means the insert resists chipping and maintains a usable edge longer than standard grades. With a 1.6 mm corner radius, the cutting edge offers enhanced strength, which reduces the likelihood of edge fracture and supports higher feed rates when permissible. The lack of a chipbreaker on this plate calls for compatible cutting strategies or dedicated chip management, but it also leaves flexibility for customised chip control via cutting parameters or holder-integrated features.

Benefit from the combination of CVD-coated carbide T515 and a robust 1.6 mm corner radius for economical, reliable cast-iron turning; order directly via Metav Werkzeuge or consult our specialists for tailored application advice. CNMA 190616 T515 — ISO turning insert (CNMA) for cast iron by Tungaloy The CNMA 190616 T515 is an ISO-format rhombic indexable insert designed for efficient external and internal turning of cast iron, offering a strong cutting edge and good chip control. CVD-coated carbide grade T515 ISO CNMA190616 rhombic 80° form 1.6 mm corner radius for robust edge 6.35 mm thickness with cylindrical hole Efficient cast-iron machining with CVD-coated carbide The CVD-coated carbide grade T515 is optimised for the economical machining of cast iron, combining wear resistance with consistent cutting performance. The CVD layer reduces flank wear under continuous cutting conditions, which translates into longer intervals between indexings and fewer tool changes. Because the cutting material is engineered for cast-iron properties, stable chip formation and predictable surface integrity are achieved, improving process reliability and lowering overall machining costs. Designed for secure clamping and ISO compatibility Compatibility with toolholders is determined by the insert’s form, rake angle, tolerance class, clamping and dimensions — all defined by the ISO format used for this series. The rhombic 80° geometry provides a large effective cutting edge and flexible approach angles, while the cylindrical hole and standard tolerance allow repeatable mounting in compatible CNMA holders. This means the insert can be mounted and secured with established holder systems, ensuring repeatable positioning and minimal set-up time. Practical guidance for turning applications The insert is intended for both external and internal turning operations; the absence of an integrated chipbreaker makes it suitable where customised chip control strategies are preferred or where rigid setups enable smooth swarf evacuation. Selection of a matching chipbreaker and the correct grade should be based on the workpiece stability, cutting interruptions and the desired cutting speed. When used under recommended conditions, the insert supports steady cutting and is particularly effective for continuous finishing passes on cast-iron components. Productivity gains and process safety in daily use By combining a robust 1.6 mm corner radius with a 6.35 mm plate thickness, the design increases edge strength and reduces the risk of premature chipping in heavier cuts. The ISO CNMA geometry offers versatile seating for varying depths of cut and feed rates, so cycle times can be optimised without compromising surface quality. For production environments seeking consistent results, the insert provides a sound balance between productivity and tool life, while compatibility with standard holders simplifies inventory and tool management.

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.
