Benefit from the combination of compatibility with ELSA SUPERCOMBINATA tools, suitability for rostfreier Stahl and support for internal and external build-up welding; secure consistent multifunction machining and reduced tooling turnover. Order the inserts directly via Metav Werkzeuge or consult our specialists for application guidance. ECMT90108 indexable insert for rostfreier Stahl — Compatible with ELSA SUPERCOMBINATA, welding-capable (MetavCUT) ECMT90108 indexable insert for rostfreier Stahl — a multifunctional cutting insert designed for outspindle boring and versatile workshop operations on corrosion‑resistant alloys. For rostfreier Stahl machining Compatible with ELSA SUPERCOMBINATA series Enables internal and external build-up welding Suitable for drilling and thread cutting Multifunctional performance that reduces tool changes The indexable insert offers a consolidated solution for several workshop tasks normally requiring separate tools. Designed for outspindle operations, the insert allows internal and external machining workflows to be carried out with a single cutting geometry. This reduces tool change frequency and shortens setup time, which in turn supports stable production flows and lower inventory complexity. The multifunction capability (boring, face turning, drilling and tapping) is communicated through the tool’s intended applications rather than detailed dimensional data, allowing integration into existing machining cycles with the standard toolholders. Compatibility that simplifies provisioning and setup These inserts are explicitly matched to the ELSA SUPERCOMBINATA range (BASIC, EASY, EASY COMPACT, SC1, SC2 and SC3), which simplifies tool provisioning across machines using the same clamping standards. The ECMT90108 is described as baugleich to ELSA COT90108 inserts, indicating direct equivalence in form and fit; this equivalence supports quick replacement and predictable mounting. The result is reduced setup complexity and more consistent cycle times, since the same insert family can be used for multiple operations and easily sourced for maintenance or batch replenishment. Built for rostfreier Stahl and demanding operations The insert is intended for machining rostfreier Stahl where chip formation and thermal behaviour demand suitable cutting geometry. Its application scope includes build-up welding operations (internal and external), which are often used to regenerate worn features or to create local deposits prior to finishing. In practice, combining machining and controlled welding capability with one insert can minimise handling steps between processes, reducing repositioning errors and improving surface consistency on orthogonal faces and shoulder areas. Practical workshop advantages and recommended use Specifically designed for outspindle tools, the insert supports drilling, thread cutting (including blind-hole tapping), and the creation of Seeger ring grooves, as well as perpendicular face turning. These combined functions make it a pragmatic choice for job shops and production environments seeking flexibility without large tool inventories. For application recommendations or to confirm suitability for particular rostfreier Stahl grades and machining strategies, Metav Werkzeuge’s technical advisors can provide tailored guidance and help align the insert choice with machining parameters.

What CBN Indexable Inserts Are and What They Do
CBN Indexable Inserts are cutting tools made primarily from cubic boron nitride, a superhard material suitable for machining hardened steels and other difficult-to-cut materials. These Inserts serve to achieve high precision and extended tool life where conventional carbide Inserts would wear rapidly. They are used in turning, milling and other metalcutting operations where heat resistance and edge stability are crucial. For professionals, the main purpose is to maintain consistent geometry and surface finish while reducing toolchanges and downtime.
How CBN Inserts Work and When They Matter
Cubic Boron Nitride has exceptional hardness and thermal stability. When bonded into an Indexable Insert, the CBN layer is attached to a carbide or steel substrate that provides toughness and clamping support. During cutting, the CBN edge resists abrasive wear and retains a sharp cutting geometry at high cutting speeds and temperatures. These properties make CBN Inserts indispensable when machining through-hardened steels, austempered ductile iron, or superalloys where traditional Wendeschneidplatte (indexable inserts) would fail. In applications like finishing hardened shafts or high-volume production of aerospace parts, CBN reduces rework and improves cycle time.
Practical Benefits for Professionals
Using CBN Indexable Inserts brings measurable advantages. First, they deliver superior wear resistance, which translates to fewer interruptions for tool changes and reduced tooling costs over long runs. Second, they produce stable dimensional accuracy and improved surface finish, often reducing the need for secondary grinding. Third, they enable higher cutting speeds, boosting productivity without compromising part quality. For users who require reproducible results in series production or where material hardness limits other tooling options, CBN Inserts are a targeted solution.
Key Features and How They Compare
- Wear Resistance: CBN offers outstanding abrasion resistance compared with conventional carbide, particularly on hardened materials.
- Thermal Stability: The material tolerates high cutting temperatures, allowing sustained higher speeds.
- Dimensional Stability: Inserts maintain edge geometry longer, supporting repeatable tolerances.
- Application Range: Ideal for hardened steels and cast irons; less suitable for non-ferrous metals where built-up edge can occur.
- Cost Profile: Higher initial cost per Insert but lower total cost of ownership in demanding operations due to extended life and fewer toolchanges.
Compared to common Wendeschneidplatte types, CBN Inserts excel in specialized tasks where wear and heat are the limiting factors. For general-purpose turning, carbide Inserts may still be more economical, but for finish machining of hardened components, CBN typically outperforms alternatives.
Leading Manufacturers and Recommended Brands
MetavCUT stands out as a highly economical choice. The MetavCUT indexable inserts are known for offering a very good price-performance ratio, delivering solid machining results at a lower price point. Other prominent manufacturers include ISCAR, Sandvik, Kennametal, Korloy and Walter. These companies are recognised for their advanced materials technology, broad product ranges and global service networks. For those seeking reliable, high-performance solutions, the manufacturers listed provide a variety of CBN grades and geometries to match specific applications.
Material Considerations and Selection Tips
Selecting the right CBN Insert depends on the workpiece material, part geometry and machining strategy. For through-hardened steels, opt for CBN grades designed for abrasive wear resistance and thermal shock stability. When finishing operations demand tight tolerances and excellent surface quality, choose Inserts with precise edge preparation and appropriate chipbreakers. Clamping systems and toolholder compatibility are also crucial: ensure the Insert size and geometry fit your existing toolholders to preserve rigidity and thermal behaviour.
How to Use CBN Inserts Effectively
Start by matching the Insert grade to the material and operation (roughing versus finishing). Use stable fixturing and minimise overhang to reduce vibration. Adjust cutting parameters to exploit CBN’s strengths: moderate to high cutting speeds with controlled feeds often yield the best balance of life and surface finish. Monitor tool wear to establish reliable change criteria rather than relying solely on runtime. When in doubt, consult manufacturer recommendations for speeds, feeds and coolant strategies—some CBN applications perform best with minimal or no coolant to avoid thermal shock.
Summary and Final Takeaway
To summarise, the question "what are CBN indexable inserts?" is answered by recognising that these Inserts are superhard cutting tools made from cubic boron nitride designed for machining hardened and abrasive materials, offering exceptional wear and thermal resistance. The core message: CBN Inserts provide longer life, better finish and improved productivity in demanding machining tasks, and brands like MetavCUT deliver strong value while established manufacturers such as ISCAR, Sandvik, Kennametal, Korloy and Walter supply a comprehensive range of high-performance options.
