CNGA120404TS-2 WBK20 Rhombic 80° indexable turning insert, Walter Tools

A CNGA120404TS-2 WBK20 indexable turning insert engineered for wear‑intensive and hardened‑steel turning tasks, offering a negative 0° rake for secure chip formation

• CBN grade WBK20 for high wear resistance
• Negative 0° rake angle for secure cutting
• Rhombic 80° form with 0.4 mm corner radius
• Two-step chipbreaker for controlled chip flow

Built for high‑duty, wear‑resistant turning

The insert’s core advantage is its CBN construction, which the WBK20 grade delivers for applications with extreme abrasion and high contact temperatures. CBN is designed primarily for hardened steels and, depending on the specific grade matrix, for certain castings or superalloys. Using a CBN insert reduces flank wear and extends tool life, which in turn lowers changeover frequency and increases uptime on serial production lines. The negative geometry contributes to a secure cutting edge under heavy engagement, improving process stability and dimensional consistency.

Geometry that balances strength and finish

A rhombic 80° shape combined with a 0.4 mm corner radius provides a robust cutting edge that tolerates interrupted cuts while still enabling acceptable surface quality in finishing passes. The 0° (negative) rake increases edge strength and reduces the tendency for chipping when machining tough or hardened materials. The tolerance class G ensures consistent fit in standard toolholders, simplifying tool inventory management and ensuring repeatable results across machines.

Controlled chip flow and integration into production

The dual chipbreaker configuration supports predictable chip formation and evacuation in a wide range of feed and depth‑of‑cut combinations. This chip control cuts down on manual intervention and reduces the risk of machine downtime due to entangled chips. The insert’s nominal size and thickness facilitate straightforward integration into existing tool systems; however, the material suitability should be checked against the product matrix to confirm optimal selection for the specific workpiece and machining conditions.

Economic and operational benefits for workshops

Adopting a CBN indexable insert from Walter Tools can lead to measurable cost‑efficiency through longer tool life and fewer tool changes in demanding turning operations. The robust design supports higher process reliability, which benefits batch production and reduces scrap rates. For workshops aiming to improve throughput while maintaining precision, this insert offers a practical balance of performance and predictable handling, backed by a recognised tooling brand.

FAQ

What materials is this insert suitable for?
The CNGA120404TS-2 WBK20 insert uses a CBN grade designed primarily for hardened steels and, depending on the grade matrix, selected castings or superalloys; consult the product matrix for exact workpiece compatibility.

How does the 0° (negative) rake affect cutting performance?
A 0° negative rake on the insert increases edge strength and resistance to chipping, making the insert suitable for heavy or interrupted cuts where a secure cutting edge is essential.

What benefit does the rhombic 80° shape provide?
The rhombic 80° geometry offers versatility in turning operations, combining edge strength for roughing with the ability to achieve good surface quality in finishing passes when using the correct feeds and speeds with the insert.

How does the chipbreaker influence machining?
The two‑step chipbreaker promotes controlled chip formation and evacuation, reducing the likelihood of chip entanglement and minimising machine stoppages during continuous production with the Walter Tools insert.

Is special tooling required to use this insert?
No special tooling beyond a compatible CNGA‑style toolholder is required; the insert conforms to standard indexable insert interfaces and tolerance class G for reliable seating and repeatable positioning.
