CCGW09T308TS-2 WBK20 — Rhombic 80° CBN turning insert by Walter Tools (CBN grade, 7° clearance)

CCGW09T308TS-2 WBK20 is a precision CBN turning insert designed for high‑wear and hard‑turning tasks, offering a robust geometry for demanding steel and superalloy machining.

• CBN grade for hardened materials
• Rhombic 80° geometry for versatile turning
• 7° clearance for stable cutting

Increased process efficiency for hardened workpieces

The combination of CBN cutting material and the WBK20 grade targets high‑wear environments where consistent edge life matters. CBN inserts resist abrasive wear in applications such as hardened steels and certain superalloys, which leads to fewer tool changes and a more predictable production rhythm. The insert’s hard substrate and coated or uncoated variants (catalogue‑dependent) allow for higher cutting speeds and a reduced total cost of machining when compared with conventional carbide solutions in similar tasks.

Geometry engineered for stability and surface quality

The rhombic 80° form paired with a 0.8 mm corner radius provides a balanced contact area that supports both corrective turning and finishing passes. A 7° clearance angle promotes positive rake behaviour and reduces rubbing on the workpiece, translating into improved surface finish and lower thermal loading of the cutting edge. Where dimensional control is critical, this geometry helps to maintain repeatable cutting conditions and lessens the likelihood of chatter in stable set‑ups.

Application guidance and safe selection

This insert is supplied in the CCGW09T308TS-2 WBK20 specification and is best considered for operations on hardened steels and materials with high abrasive tendencies; however, final suitability should be verified against the manufacturer’s product matrix. The chipbreaker 2 configuration supports controlled chip formation in interrupted or continuous turning, improving evacuations in automated or semi‑automated machining. For specific cutting data and to match the insert to the machine and workpiece, consult the technical data sheets or request assistance from Metav Werkzeuge.

Practical benefits for production planners

Adopting a CBN insert such as this one can shorten cycle times through higher permissible cutting speeds and reduce tooling logistics by extending tool life. The T3 thickness and standard plate size 09 make the insert compatible with a wide range of common tool holders, simplifying inventory. In practice, shops report greater process stability and fewer unexpected stoppages when switching to a purpose‑designed CBN grade for hard‑turning tasks.
