CNMA 160612 T5105 Wendeplatten - Tungaloy
Combining CVD-coated carbide durability with an ISO CNMA form and a 1.2 mm corner radius yields a robust solution for high-speed cast iron turning; stable clamping via the cylindrical hole and the standard 6.35 mm plate thickness support consistent repeatability. Order inserts directly via Metav Werkzeuge or consult the technical team for holder matching. CNMA 160612 T5105 Tungaloy turning insert (ISO CNMA160612) — CVD-coated carbide, R1.2 The CNMA160612 T5105 is an ISO turning insert engineered for stable high-speed machining of cast iron in external and internal turning applications. CVD-coated carbide for high wear resistance ISO CNMA160612 rhombic insert, 80° geometry R1.2 corner radius for finishing and semi-finishing Cylindrical central hole for secure clamping Stable high-speed performance for cast iron The CVD-bonded grade T5105 is formulated for wear resistance during high cutting speeds, which supports longer tool life under steady machining conditions. The rhombic, 80° geometry provides a predictable cutting angle that reduces vibration in many lathe set-ups, meaning the insert maintains edge integrity for longer when machining cast iron. This results in fewer insert changes per shift and a more continuous production flow, both of which contribute to process reliability and reduced downtime. Precise fit, secure clamping and repeatability Compatibility with toolholders depends on form, clearance angle, tolerance class, mounting and the plate’s dimensions; the CNMA format and cylindrical hole enable positive clamping and repeatable positioning. The plate thickness of 6.35 mm and the nominal size 16 provide a stable contact surface, while the 0° relief ensures the intended rake and clearance are preserved when paired with matching holders. These characteristics reduce runout and support consistent surface finish across batches. Why the material and coating matter The insert’s carbide substrate with a CVD coating offers a balanced combination of toughness and thermal resistance. CVD layers increase resistance to abrasive and diffusion wear at elevated temperatures typical of high-speed turning, so chip formation remains stable and flank wear is delayed. For operations where repeatable dimensional control and surface quality are required, this coated carbide option enables higher cutting speeds compared with uncoated grades, while preserving dimensional stability on cast-iron components. Practical application and assembly guidance With an R1.2 corner radius the insert suits finishing and light semi-finishing passes, delivering a controlled edge for improved surface quality. The absence of a dedicated chipbreaker on this insert means the chip control strategy must be selected according to workpiece geometry and machine rigidity; pairing the insert with an appropriate holder, or a suitable shim/clamp set and replacement screws, completes the system. The recommended system components are the ISO turning insert itself, a compatible external holder or boring bar, and the matching shim/clamp set to ensure secure engagement and repeatable clamping accuracy.

Order the original inserts via Metav Werkzeuge or ask the consultants for holder compatibility. CNMA 160616 T515 Turning insert — Tungaloy CNMA160616 T515 is an ISO rhombic turning insert designed for economic machining of cast iron in ISO CNMA systems CNMA 160616 ISO designation CVD-coated T515 carbide grade Designed for cast iron turning Rhombic form with 80° included angle Consistent performance in cast iron turning The CNMA160616 design combines a CVD-coated carbide substrate with the T515 grade to provide wear resistance and stable edge behaviour during continuous cutting of cast iron. The CVD coating (chemical vapour deposition) forms a hard outer layer that improves abrasion resistance and extends effective tool life, which translates into fewer insert changes and higher productive uptime. For practical use this means consistent surface finish and predictable tool-change intervals in serial turning operations. Secure clamping and ISO compatibility for reliable production Compatibility is determined by form, clearance angle 0°, tolerance class, fastening, size and thickness; the rhombic geometry with an 80° included angle and a cylindrical central hole ensures secure seating in standard CNMA-compatible toolholders. Secure clamping reduces chatter and vibration, improving both tool life and dimensional consistency. The indexable insert format simplifies tool replenishment and reduces setup-related downtime in a production environment. Practical dimensions and machining benefits for workshop efficiency With a nominal size of 16 mm, a thickness of 6.35 mm and a corner radius of 1.6 mm, this insert balances edge strength and cutting performance: the 1.6 mm radius increases corner robustness for medium-heavy cuts while still allowing acceptable surface quality. The absence of an integral chipbreaker means this insert is best applied where chip evacuation is uncritical or where external chip control measures are in place; selecting an appropriate holder and cutting parameters optimises chip flow. For tailored recommendations on speeds and feeds for specific cast iron grades, Metav Werkzeuge provides technical guidance.

The CNMA160616 T515 insert is engineered primarily for machining cast iron; the T515 CVD-coated carbide grade offers abrasion resistance suitable for a broad range of grey and ductile cast irons. How does the 1.6 mm corner radius affect cutting? A 1.6 mm corner radius provides enhanced corner strength for medium to heavy cutting, reducing the risk of edge chipping and supporting stable tool life under higher feed rates. Is a chipbreaker required with this insert? This insert is supplied without a chipbreaker; pairing the insert with a compatible holder and optimised cutting parameters is recommended to control chip formation and evacuation. Which holders are compatible with this insert? Compatibility depends on holder form, tolerance class, fastening method, size and thickness; use holders specified for CNMA inserts with an 80° included angle and matching seat geometry for secure clamping. What benefits does the CVD coating provide? The CVD coating improves surface hardness and wear resistance, leading to longer edge life and consistent cutting performance, especially in abrasive cast iron applications.

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?
Metav supplies a broad range of indexable inserts and tooling, backed by decades of expertise and a comprehensive European stock, making it a practical choice for consistent quality and dependable delivery.
