DCGW11T308TM-2 WBH30 indexable turning insert — CBN grade for hard turning (Walter Tools)

The DCGW11T308TM-2 WBH30 is a rhombic 55° indexable turning insert with a CBN grade designed for hard turning of hardened steels and pre-hardened materials.

• CBN grade WBH30 for hard turning
• Rhombic 55° geometry for stable cutting
• 7° relief angle for consistent chip control
• 0.8 mm corner radius for robust edge

High-performance CBN grade for demanding hard turning

The core advantage of the WBH30 cutting grade is its CBN composition, developed specifically for machining hardened steels (ISO 513 group H). This mineral-based superabrasive provides exceptional wear resistance and a stable cutting edge when temperatures and contact stresses are high. For production environments where repeatability and process security matter, the insert reduces the frequency of edge changes and supports consistent part tolerances, translating into fewer interruptions and a more reliable workflow.

Geometry that balances strength and surface quality

The insert’s rhombic 55° form and 7° relief are chosen to combine access in tight profiles with positive chip flow. The 0.8 mm corner radius strengthens the cutting edge against chipping while helping produce a superior surface finish compared with sharper geometries. The medium-thickness T3 body gives sufficient rigidity for interrupted cuts, and the integrated chipbreaker (type 2) assists in forming short, controllable chips during hard turning—so the machining process remains stable even under elevated cutting forces.

Productivity gains through repeatable performance

By using a CBN solution from the Walter CBN / Hartstoff series, workshops can expect extended edge life and consistent component quality across batches. The insert’s WBH30 grade is particularly suitable when machining pre-hardened or through-hardened components, where conventional carbide would wear rapidly. The result is increased uptime, lower insert consumption per part and predictable tool-change intervals—advantages that support tighter production planning and a better return on cutting tool investment.

Application guidance and compatibility

The insert is specified for hard and pre-hardened steels and is intended for turning operations requiring a robust edge and reliable chip formation. The designation indicates suitability for ISO group H materials; when integrating this insert into a machining process, match the clamping and seat conditions of the toolholder to the rhombic 55° geometry and consult the manufacturer’s cutting data for feed and speed recommendations.

FAQ

What materials is this insert designed for?
The DCGW11T308TM-2 WBH30 insert is designed primarily for hardened steels (ISO 513 H) and is suitable for pre-hardened workpieces where a CBN grade is required.

How does the CBN WBH30 grade benefit production runs?
WBH30 offers extended edge life and stable wear behaviour, which helps maintain consistent part quality and reduces the frequency of insert changes during long production runs.

What machining advantages does the rhombic 55° form provide?
The rhombic 55° geometry enables better access to profiles and combines rigidity with a favourable cutting direction to improve surface finish and tool stability in turning operations.

Is the 0.8 mm corner radius suitable for interrupted cuts?
Yes, the 0.8 mm corner radius increases edge strength and is advantageous for interrupted cuts, offering improved resistance to chipping compared with smaller radii.

Where can cutting data and holder recommendations be obtained?
Cutting data and toolholder compatibility guidance are available from Metav Werkzeuge; consult the technical team to match the DCGW11T308TM-2 WBH30 insert to the specific turning application.
