CCGW09T308TM-MW2 WBH10C - Rhombic 80° CBN turning insert for hardened steel (Walter Tools)

The CCGW09T308TM-MW2 WBH10C is an indexable turning insert designed for hard machining tasks, offering a coated CBN grade for high wear resistance and consistent performance in hardened-steel applications

• Coated CBN for hard turning
• Rhombic 80° geometry for versatility
• 0.8 mm corner radius for edge stability
• 7° clearance angle for reliable cutting

Consistent wear resistance for demanding hard turning

The WBH10C grade is a coated CBN cutting material developed to withstand the high temperatures and abrasive conditions typical of hardened-steel machining. As a result, the insert delivers extended tool life and reduced flank wear compared with conventional carbide solutions when applied correctly. CBN (cubic boron nitride) is a superabrasive optimised for permanent hardness and thermal stability; this means the insert maintains cutting-edge geometry under heavy contact stresses, which translates into fewer tool changes and more predictable machining cycles for production environments

Geometry and chip control that improve surface quality

With a rhombic 80° shape and a 0.8 mm corner radius, this insert combines edge strength with flexible approach angles to achieve consistent surface finish and dimensional stability. The integrated MW2 chipbreaker promotes reliable chip formation during interrupted cuts and finishing passes, reducing the risk of built-up edge and improving swarf evacuation. The modest 7° clearance ensures a controlled cutting engagement and lowers rubbing at the flank, resulting in stable forces and reproducible part quality in serial production

Practical advantages for workshop integration and application

The insert's T3 plate thickness and tolerance class G offer mechanical robustness and repeatable seating in standard toolholders, supporting process security across shifts. Designed for machining hardened steels and pre-hardened materials, it is suitable for hard turning operations where wear resistance and edge life are critical. Use of a CBN grade minimises thermal deformation of the cutting edge and often enables higher cutting speeds or longer cycles between indexings, improving throughput and cost-efficiency for medium to high-volume production

FAQ

What materials is this insert suitable for?
This insert is specified for machining hardened steels and is suitable for pre-hardened steel applications, using the WBH10C CBN grade to control wear during hard turning

How does a CBN grade compare with carbide for hard machining?
Coated CBN, as used in this insert, offers superior thermal and abrasive resistance compared with carbide in hardened materials, resulting in longer edge life and more consistent dimensional output when machining hard workpieces

What does the MW2 chipbreaker achieve in practice?
The MW2 chipbreaker supports controlled chip formation and improved evacuation, reducing the risk of built-up edge and helping to maintain a consistent surface finish during interrupted or continuous hard-turning operations

Which toolholders fit this insert form and size?
The rhombic 80° form and size 09 are compatible with standard indexable turning holders designed for CCGW-style inserts; selection of the correct holder and clamping torque ensures the T3 thickness and tolerance class G provide repeatable seating

How should cutting data be adjusted for this insert?
Cutting parameters depend on the workpiece hardness and machine rigidity; start with manufacturer-recommended speeds for CBN in hardened steels and favour stable feeds and depths of cut to exploit the insert’s wear resistance and process stability
