DCGW11T308TM-2 WBH20 indexable turning insert (CBN, Rhombic 55°, 7° relief) — Walter Tools

DCGW11T308TM-2 WBH20 is an indexable turning insert developed for hard machining tasks, optimised for high wear resistance and reproducible cutting performance in hardened and pre-hardened steels.

CBN grade WBH20 for hardened steels
Rhombic 55° shape for versatile turning
7° relief angle for secure cutting
0.8 mm corner radius for stable edge

Engineered for hard turning with reproducible tool life

The DCGW11T308TM-2 WBH20 insert uses a CBN-based grade tailored to high-wear applications; CBN provides exceptional abrasion resistance when machining hardened steels, which reduces flank wear and extends productive cutting time. This means fewer tool changes and more consistent cycle times across series production runs. For operations where tool life and repeatability influence process cost, the insert delivers a measurable contribution to overall efficiency while maintaining component tolerances.

Geometry that stabilises cuts and improves surface finish

The insert’s Rhombic 55° form and 7° relief establish a secure engagement with the workpiece and controlled chip flow; the 0.8 mm corner radius favours strength at the cutting edge and helps dampen vibration, resulting in improved surface integrity. The combination of geometry and edge preparation supports a stable cutting action even under elevated contact conditions, translating into fewer rework steps and a more reliable surface finish on turned parts.

Process reliability and economical machining

Belonging to the Walter CBN / hard material series, the grade WBH20 is designed specifically for hard machining applications and is suitable for both hardened and pre-hardened steel work. The insert’s resistance to abrasive wear provides greater process stability and reduces the frequency of insert indexing, supporting continuous production. Where cycle stability is critical, this indexable insert contributes to predictable tool-change intervals and helps to lower total machining costs through extended service life.

Clear specification and application guidance for shop-floor integration

The insert is supplied in a size 11 format with T3 thickness, a defined chipbreaker class and tolerance class G, making it straightforward to match to compatible toolholders. Its defined geometry and material designation simplify process planning for hard turning operations in automotive, tooling and engineering sectors. For selection of the correct holder and cutting parameters, Metav Werkzeuge’s technical team can provide tailored recommendations to ensure the insert meets the intended production requirements.

FAQ

What materials is this insert suitable for?
The DCGW11T308TM-2 WBH20 insert (Walter Tools indexable turning insert) is intended for machining hardened steels and can also be used on pre-hardened steel, as indicated by its CBN-based WBH20 grade.

How does the CBN grade affect tool life?
The WBH20 CBN grade provides high abrasion resistance, which reduces flank wear during hard turning and therefore extends the useful life of the insert in demanding applications.

Which geometry features improve surface finish?
The combination of a Rhombic 55° shape, 7° relief and a 0.8 mm corner radius results in a more stable cutting edge and controlled chip formation, contributing to improved surface integrity on turned components.

Is this insert compatible with standard toolholders?
The insert’s size and form follow common indexable insert conventions; selection of an appropriate holder should be confirmed, and Metav Werkzeuge can advise on compatible clamping systems and cutting data for the DCGW11T308TM-2 WBH20.

What production benefits can be expected from using this insert?
Using the WBH20 CBN insert typically yields longer service intervals, greater process stability and fewer tool changes during hard machining, which together support improved throughput and reproducible quality.
