CNGA120404EM-2 WBS10 WBS10 Wendeplatten - Walter Tools
Benefit from high wear resistance and stable chip control combined with a geometry that supports precise, repeatable turning results; order the CNGA120404EM-2 WBS10 insert directly via Metav Werkzeuge or consult our specialists for application advice. CNGA120404EM-2 WBS10 indexable turning insert by Walter Tools — CBN grade, Rhombus 80° geometry CNGA120404EM-2 WBS10 is an indexable turning insert designed for hardened-material and high-wear machining tasks, offering a robust CBN grade and an 80° rhombic shape for secure seating and consistent cutting performance. *CBN grade WBS10 for hard materials *Rhombus 80° geometry for precise engagement *0° negative rake for stable cutting *0.4 mm corner radius for consistent surface finish High-performance CBN for demanding, wear‑intensive turning The CBN-based WBS10 grade is engineered for hard turning and other high-wear operations, delivering excellent wear resistance and sustained edge life under thermal and abrasive stress. As a cubic boron nitride solution, the material maintains cutting integrity where conventional carbides wear rapidly; this means fewer indexings and predictable tool cycles. The robust substrate and grade selection result in improved process stability, particularly when machining through-hardened steels or components where surface integrity is critical. Practical application requires verification against the specific product matrix to confirm suitability for alloys such as certain cast irons or superalloys. Geometry that ensures repeatable surface quality and tool life The Rhombus 80° form combined with a 0° negative rake creates a cutting edge that resists deflection and secures seating in standard toolholders, which promotes dimensional constancy across long production runs. The 0.4 mm corner radius favours a balanced compromise between edge strength and achievable surface finish, reducing the tendency for micro-chipping while supporting stable chip formation. Users with limited metrology experience should note that corner radius and negative rake affect cutting forces and must be considered when selecting feeds and depths of cut to preserve component tolerances. Practical integration into machining workflows The insert is supplied in the Walter CBN / Hartstoff series and is intended to be matched with holder systems and cutting data recommended for CBN grades. For best results, consult the cutting data sheet and validate parameters on representative parts; the product matrix should be used to confirm material compatibility and cutting-window optimisation. Where process reliability and repeatable part quality are priorities, this insert offers a rational route to fewer reworks and higher throughput. For tailored recommendations or requests for detailed cutting data, Metav Werkzeuge provides application support and sample guidance.

The CNGA120404EM-2 WBS10 insert is formulated as a CBN grade for hardened and highly abrasive materials; suitability should be checked against the product matrix for specific steels, certain cast irons or superalloys. How does the 0° negative rake influence cutting behaviour? A 0° negative rake increases edge strength and improves stability under heavy loads; the CNGA120404EM-2 WBS10 therefore delivers consistent cutting forces and enhanced tool life in demanding turning operations. Is the 0.4 mm corner radius suitable for finishing passes? A 0.4 mm radius provides a balance between edge durability and surface quality; for critical finishing passes, adjust feeds and depths to the required surface finish while leveraging the insert’s stable edge. Which series and manufacturer standard does this insert belong to? This insert is part of the Walter CBN / Hartstoff series by Walter Tools and should be integrated using the manufacturer’s recommended holders and cutting data.

CNGA120404SM-MWS WCH10C Wendeplatten - Walter Tools
Take advantage of the combination of high wear resistance, stable chip control and robust edge security for efficient hard-turning operations; order the CNGA120404SM-MWS WCH10C insert via Metav Werkzeuge or discuss process parameters with our consultants for optimal integration. CNGA120404SM-MWS WCH10C indexable turning insert – Coated ceramic grade for hardened steels, Walter Tools The CNGA120404SM-MWS WCH10C is an indexable turning insert engineered for hard machining of hardened steels, combining a coated ceramic cutting grade with an MWS chipbreaker and rhombic 80° geometry for reliable, high-temperature performance. Coated ceramic WCH10C for hard turning MWS chipbreaker for stable chip control Rhombic 80° geometry for versatile machining Negative 0° rake, 0.4 mm corner radius High wear resistance for hard materials The insert’s WCH10C cutting grade is a coated ceramic designed specifically for demanding hard-turning tasks. Ceramic materials retain hardness at elevated temperatures, so the cutting edge resists abrasion and thermal softening during continuous operation. This results in consistent edge life and fewer unplanned tool changes. For workshops processing quenched or tempered components, the combination of ceramic chemistry and robust bonding offers measurable improvements in longevity compared with conventional carbide solutions. Stable chip control and improved surface outcomes A precisely engineered MWS chipbreaker promotes predictable chip formation even under high cutting forces, reducing risk of chip entanglement and machine downtime. The rhombic 80° shape provides flexible approach angles, while the 0° (negative) relief increases insert strength for interrupted cuts. The modest 0.4 mm corner radius supports better edge security and surface finish on tight tolerance components, translating directly into reduced rework and higher first-pass yield. Boosting process reliability and productivity Tailored for the ISO group H (hardened steels), this insert supports stable material removal rates at elevated temperatures, improving cycle-time predictability. The robust grade and geometry deliver process reliability, which helps to plan tool-change intervals and lower overall tooling costs. When introduced into an established turning cell, the result is a more uniform tool life distribution and improved capacity planning—advantages that scale from job shops to production lines. Practical designation and handling for integration The insert is listed as CNGA120404SM-MWS WCH10C and conforms to a familiar rhombic form factor that fits many compatible tool holders. The tolerance class G ensures interchangeability and repeatable clamping behaviour, simplifying set-up and measurement routines. Operators benefit from the straightforward identification of chipbreaker and grade markings, which aids stock management and supports consistent tool selection across multiple machines.

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.
