CCGW09T308TM-2 WBH30 rhombic 80° CBN insert for hard turning — Walter Tools

The CCGW09T308TM-2 WBH30 is a rhombic CBN insert engineered for heavy‑duty turning and boring of hardened steels, delivering stable chip control and long tool life.

• CBN grade WBH30 for hard materials
• Rhombic 80° geometry
• 7° clearance for stable cutting
• 0.8 mm corner radius for edge strength

Durable performance for hardened steel machining

The CBN cutting compound of this insert provides exceptional wear resistance, making it ideal for repeated operations on hardened steels. By using a cubic boron nitride grade tailored for hard‑turning, the insert reduces flank wear and maintains a consistent cutting edge over extended cycles. This results in fewer tool changes and more predictable cycle times, which supports higher process reliability in serial production.

Geometry designed to withstand heavy cuts

The rhombic 80° shape and 0.8 mm corner radius combine to deliver a robust cutting edge that resists chipping under elevated radial and tangential forces. The 7° clearance angle improves chip flow and reduces rubbing on the flank, which helps preserve surface integrity on the workpiece. Together, these geometric choices enable stable machining of hard materials while maintaining a competitive surface finish.

Improved productivity through longer tool life

Using a CBN insert from the Walter CBN series reduces downtime associated with frequent insert changes and rework. The WBH30 composition is optimised for abrasive, high‑hardness environments; this increases cumulative cutting performance and lowers cost per component. For operations where repeatability and uptime are critical, the combination of coated CBN grade and proven insert geometry provides a measurable productivity advantage.

Application guidance and material compatibility

This insert is intended for hard machining tasks and is suitable for materials classified under ISO group H, notably hardened steels and pre‑hardened workpieces. The Walter CBN / Hartstoff series is formulated for challenging abrasion and maintains edge stability during intermittent or continuous cuts. When integrating this insert into a process, select appropriate cutting parameters and coolant strategies for CBN tooling to exploit the full benefit of the grade and geometry.

FAQ

What materials is this insert best suited for?
The insert is intended for hard‑turning and is suitable for materials in ISO group H, particularly hardened steels and pre‑hardened workpieces; the WBH30 CBN grade is optimised for such applications.

How does the 0.8 mm corner radius affect cutting?
A 0.8 mm corner radius increases edge strength and improves resistance to chipping during heavy cuts, which helps maintain dimensional stability and surface quality over longer tool life.

Is the geometry suitable for finishing passes?
The rhombic 80° form with a moderate corner radius provides a balance between robust cutting for semi‑finishing and the potential for achieving good surface finish when cutting parameters are adapted.

What does the tolerance class G indicate?
Tolerance class G specifies the manufacturing tolerance for the insert geometry; this influences fit and repeatability in insert seats and supports consistent performance across batches for the CCGW09T308TM-2 WBH30 insert.
