DCGW11T302TM-2 WBH30 — Walter Tools turning insert, CBN grade for hardened steels

The DCGW11T302TM-2 WBH30 is a turning insert engineered for hard machining of hardened steels, combining a CBN cutting material and a rhombic 55° shape for consistent wear resistance.

• CBN grade WBH30 for hard materials
• Rhombic 55° geometry for versatility
• 7° relief angle for stable cutting action
• 0.2 mm corner radius for fine surface finish

High-performance cutting for hardened materials

The WBH30 grade is a CBN (cubic boron nitride) compound developed specifically for demanding hard-turning tasks. As a superabrasive, CBN resists thermal and abrasive wear far better than conventional carbide, which translates into longer service life and fewer insert changes in series production. This characteristic provides a measurable improvement in process economy and reduces unplanned downtime during machining of hardened steels. The material pairing and edge stability make this insert suited for applications where consistent dimensional accuracy and repeatability are required.

Geometry that balances strength and accessibility

The rhombic 55° form offers a combination of accessibility to external contours and favourable cutting forces, while the 7° relief creates a positive rake that helps maintain a stable cutting edge under the elevated forces of hard machining. The small 0.2 mm corner radius supports fine finishing passes and helps achieve improved surface integrity without sacrificing edge strength. Together, these geometry choices permit both roughing and light finishing operations with a single indexable solution, simplifying tool set-ups and reducing tooling variants in the tool crib.

Controlled chip formation and predictable tool life

Equipped with chipbreaker 2, the insert promotes predictable chip control during interrupted cuts and continuous hard-turning cycles. Controlled chip formation limits the risk of re-cutting and cradle-falls while stabilising cutting forces, which in turn supports repeatable component quality. The insert’s CBN composition contributes to a predictable wear pattern that is easier to schedule and monitor, enabling process engineers to plan insert changes on defined production intervals rather than reactive interventions.

Application focus and process integration

Designed within the Walter CBN / Hartstoff series, this insert is intended for hard machining of through-hardened or pre-hardened steels and other highly abrasive materials where conventional grades would wear prematurely. Its compatibility with hardened materials (designation H) means that the component groups defined under ISO 513 for hard steels are directly addressable with this solution. Selection of cutting parameters and stable clamping systems will further enhance the insert’s performance and support consistent cycle times in production environments.

FAQ

Is this insert suitable for through-hardened steels?
Yes. The DCGW11T302TM-2 WBH30 uses a CBN grade designed specifically for hardened materials and is suitable for machining through-hardened and pre-hardened steels.

What advantages does the WBH30 grade provide over carbide?
The WBH30 CBN grade provides superior resistance to abrasive and thermal wear compared with carbide, resulting in longer tool life and more consistent part dimensions during hard machining.

Can this insert handle interrupted cuts and roughing?
The combination of the rhombic geometry, 7° relief, and chipbreaker 2 supports controlled chip formation and stable cutting forces, making it appropriate for many interrupted-cut and roughing scenarios in hardened materials.

How does the 0.2 mm corner radius affect the finish?
A 0.2 mm corner radius helps achieve finer surface finishes while maintaining sufficient edge strength for typical finishing and semi-finishing passes in hard turning operations.

Is this insert part of a dedicated product series for hard machining?
Yes. The insert belongs to the Walter CBN / Hartstoff series and is optimised for hard machining tasks where wear resistance and process stability are priorities.
