CCGW09T304TM-2 WBH20C – indexable turning and boring insert, coated CBN for hardened steels (Walter Tools)

The CCGW09T304TM-2 WBH20C is an indexable turning and boring insert engineered for hard machining, providing durable performance where wear resistance and dimensional stability are critical

• Coated CBN grade WBH20C for wear resistance
• Rhombic 80° shape for versatile turning and boring
• 7° clearance for stable cutting geometry
• 0.4 mm corner radius for improved surface finish

Consistent tool life through coated CBN technology

The WBH20C grade is a coated CBN cutting material developed for demanding hard-turning tasks. As a coated cubic boron nitride grade, it delivers high wear resistance and stable edge retention when machining hardened steels (ISO group H). This stability reduces insert change frequency and supports longer uninterrupted production runs, improving overall throughput while keeping scrap and rework to a minimum. The combination of a wear-resistant grade and secure edge geometry translates into measurable productivity benefits and predictable performance in serial machining.

Precise geometry for repeatable dimensional control

The rhombic 80° shape paired with a 7° clearance angle and 0.4 mm corner radius helps to maintain cutting forces within a controlled band, which is essential when machining already hardened components. The geometry supports stable chip formation and consistent contact between insert and workpiece, reducing chatter and improving tolerance adherence. For operations that require both light finishing passes and stronger engagement for semi-finishing, this insert geometry delivers a balance between rigidity and accessibility, resulting in improved surface quality and less post-process finishing.

Designed for hard machining and process security

With a plate designation of CCGW09T304TM-2 and T3 thickness, this insert is built for robust clamping and reliable heat dissipation under elevated cutting stresses. The Walter CBN / hard-material series is intended primarily for hard machining applications; the grade and geometry are optimised to handle the high contact stresses associated with hardened steels and pre-hardened components. Process planners will appreciate the predictable wear behaviour and the suitability for both semi-finish and finish cuts, which supports reduced tool inventory and clearer tool-life forecasting — a direct contribution to manufacturing cost control.

Practical application advice and integration into production

The insert’s chipbreaker 2 design and rhombic form make it compatible with a range of toolholder styles for internal and external turning operations; correct selection of toolholder and cutting data remains pivotal. When integrated into a stable holder and paired with appropriate cutting parameters, the insert provides reliable removal rates and surface integrity for hardened components. For material groups outside ISO H, evaluation is recommended, but within the intended scope the insert supports repeatable results and fewer process interruptions. For tailored cutting-parameter recommendations and sample calculations, consult our technical team to achieve the best combination of speed, feed and depth for the application.

FAQ

What materials is this insert designed for?
The insert is specified for hardened steels (ISO group H); the WBH20C coated CBN grade is optimised for high-wear, hard-turning applications.

Can the insert be used for both boring and external turning?
Yes, the rhombic 80° form and chipbreaker provide versatility for internal boring and external turning operations when used with a suitable toolholder.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius offers a compromise between edge strength and surface quality, delivering improved surface finish without compromising the insert’s resistance to edge chipping.

Is the insert suitable for pre-hardened steels?
The insert supports machining of pre-hardened steel; its coated CBN composition and robust geometry are intended to handle elevated contact stresses encountered with pre-hardened materials.

What information identifies this specific product for ordering?
Order or reference by the designation CCGW09T304TM-2 WBH20C and SKU CCGW09T304TM-2-WBH20C-WALTER to ensure the correct Walter Tools CBN insert is supplied.
