CCGW060204TM-2 WBH30 – Rhombic 80° CBN turning/boring insert for hard turning by Walter Tools

The CCGW060204TM-2 WBH30 is a rhombic 80° CBN indexable insert designed for demanding hard-turning applications and the machining of hardened steels.

• CBN grade WBH30 for hard turning
• Rhombic 80° geometry, 0.4 mm corner radius
• 7° clearance angle for stable cutting
• Suitable for hardened steels and pre-hardened parts

Increased process stability for hard machining

The CCGW060204TM-2 WBH30 insert combines the CBN cutting material with a geometry optimised for stability, delivering a stable cutting edge and reduced flank wear during high-stress operations. This results in fewer interruptions, longer index life and more predictable tool-change intervals, which in turn supports a more efficient production rhythm. The rhombic 80° form contributes to secure seating in standard holders while the chipbreaker 2 geometry helps control chip flow under heavy cutting loads. For operations where repeatability and minimal rework are critical, the combination of grade and geometry increases overall process security.

Consistent surface quality and dimensional control

A precise 0.4 mm corner radius together with the 7° clearance creates a consistent contact zone that reduces vibration and prevents premature edge chipping. This leads to improved surface finish and tighter dimensional tolerance over extended runs. The insert’s design supports finishing passes as well as roughing steps in a hard-turning sequence, reducing the need for separate tools. When machining hardened steels, the predictable edge behaviour of this insert helps maintain part quality across batches, making it suitable for components that require repeatable geometric and surface specifications.

Long tool life in abrasive and hard materials

The WBH30 grade is a CBN-based solution engineered for wear resistance in high-hardness environments. Its composition and microstructure are selected to withstand elevated temperatures and abrasive contact typical of hardened and pre-hardened steels, delivering high wear resistance and reliable performance. By using a CBN grade tailored to hard machining, the insert reduces the frequency of tool changes and contributes to lower overall machining costs per component, particularly in production scenarios with substantial volumes or tight cycle time requirements.

Practical benefits for workshop integration

The insert’s standard form and size ensure compatibility with a wide range of indexable tool holders, supporting straightforward tool management and inventory control. Markings such as the rhombic rhombic 80° geometry and the tolerance class G help with quick identification and placement in automated tool changers or manual setups. Operators benefit from the predictable cutting characteristics when setting up turning cycles for hard materials, and production planners benefit from the increased uptime and fewer emergency replacements. For those seeking to standardise hard-turning tooling across machines, this insert offers a robust and application-focused option.

FAQ

What materials is this insert intended for?
The CCGW060204TM-2 WBH30 is intended primarily for hardened steels and pre-hardened applications; the WBH30 CBN grade is optimised for hard and abrasive workpieces.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm corner radius provides a balance between strength and surface finish, reducing the risk of edge breakage while enabling acceptable finishes in hard-turning operations with the Walter Tools insert.

Can this insert be used for finishing passes?
Yes, the combination of the CBN grade and the rhombic geometry supports finishing operations on hardened components while maintaining dimensional stability and surface quality.

What does tolerance class G mean for this insert?
The tolerance class G indicates the manufacturing precision of the insert, ensuring consistent seating and repeatable positioning in compatible tool holders during index changes.

Is the insert compatible with standard holders for rhombic 80° inserts?
The insert’s rhombic 80° form and common size coding (06) make it compatible with standard holders designed for this geometry; check holder specifications for thickness and clamping style.
