CCGW09T308TM-2 WBH20 indexable insert for hard machining — Walter Tools (CBN grade, Rhombic 80°)

The CCGW09T308TM-2 WBH20 is an indexable turning and boring insert engineered for hard machining of hardened steels and similar challenging materials, offering high wear resistance and consistent performance.

• CBN grade WBH20 for hard machining
• Rhombic 80° insert form
• 7° clearance for stable cutting
• 0.8 mm corner radius for edge strength

Optimised CBN grade for durable hard machining

The WBH20 grade uses CBN (cubic boron nitride) as the cutting material, which is purposely formulated for high-wear tasks on hardened steels (ISO 513 group H). This results in reliable tool life and lower frequency of insert changes compared with conventional carbide in similar applications. The material's inherent abrasion resistance reduces flank wear, supporting longer uninterrupted production runs and fewer process interruptions, which in turn helps to maintain consistent batch quality and reduce scrap rates.

Geometry that improves process stability and surface finish

The Rhombic 80° form combined with a 7° clearance angle delivers a robust cutting geometry that resists edge chipping during interrupted cuts and heavy engagement. The 0.8 mm corner radius increases edge strength while still permitting acceptable surface quality on finishing passes. The integrated chipbreaker 2 promotes controlled chip formation in hard turning, reducing the risk of entanglement and safeguarding both the workpiece and the toolholder. Together these features contribute to predictable cycle times and improved first-pass yield.

Practical benefits for production planning and machining security

Designed as part of the Walter CBN / Hartstoff series, this indexable insert supports a targeted strategy for hard finishing and hard turning operations, offering process security and repeatable results. Specified tolerance class G and the insert's standardised designation make tool management straightforward and reduce setup variability. Use of a CBN-grade insert like this one can lower overall tooling consumption and contribute to more efficient scheduling by extending service intervals and simplifying inventory choices for hardened-steel applications.

FAQ

What materials is this insert suitable for?
The CCGW09T308TM-2 WBH20 insert is designed primarily for hardened steels (ISO 513 group H) and related hard materials; its CBN cutting grade provides the required wear resistance for these applications.

How does the Rhombic 80° shape affect cutting performance?
The Rhombic 80° geometry gives a robust cutting edge that tolerates higher radial forces and interrupted cuts, improving process stability and enabling secure edge positioning in a range of turning and boring setups.

What advantage does the 0.8 mm corner radius provide?
A 0.8 mm corner radius increases edge strength and reduces the likelihood of chipping when machining hard materials, helping to preserve surface integrity and extend the usable life of the insert.

Is this insert compatible with standard toolholders for CCGW-style inserts?
The insert follows the CCGW designation and is compatible with toolholders designed for that family; for confirmation of holder fitment and clamping specifications refer to tooling documentation or consult Metav Werkzeuge.
