DCGW11T304TM-2 WBH20C turning insert — Walter Tools — CBN grade for hard turning, Rhombic 55°

A high-performance indexable turning insert designed for hard and pre-hardened steels, offering a coated CBN grade and a robust rhombic geometry for stable metal removal.

• Coated CBN grade for hard turning
• Rhombic 55° insert geometry
• 7° relief angle for improved clearance
• Corner radius 0.4 mm for predictable edge life

Engineered for reliable hard-turning productivity

The coated CBN composition is optimised for machining hardened steels, which demand exceptional wear resistance and thermal stability. This insert provides a durable cutting edge that preserves geometry under the high contact temperatures and forces typical of hard turning. The result is long tool life and fewer tool changes, which directly improves process throughput and reduces production cost-per-part. The indexable design permits quick indexing and predictable tool change intervals, supporting continuous operation in demanding CNC turning centres.

Geometry that promotes consistent surface quality and chip control

The rhombic 55° shape combined with a 7° relief and a corner radius of 0.4 mm delivers a balance between strength and cutting engagement. This geometry aids in producing a stable cutting force vector and controlled chip breakage, which helps to maintain precision and surface finish across long production runs. Where tight tolerances are required on pre-hardened components, the combination of geometry and the CBN grade reduces the tendency for built-up edge and chatter, supporting repeatable results.

Practical benefits for workshop and production planning

Thanks to its wear-resistant compound and compact dimensions (insert size 11, thickness T3), the insert supports high productivity in batch and single-piece flow environments. The specification reduces unplanned interventions by lowering flank and crater wear rates, so tool-life planning becomes more reliable. For operations moving between heat-treated parts and pre-hardened workpieces, this insert offers a cost-effective route to maintain cycle times while reducing scrap and rework.

Clear application guidance and material fit

The insert is especially suited to the ISO H material group — hardened steels — and is recommended for precision hard turning and finishing passes where dimensional stability matters. Its chipbreaker and edge geometry help manage the tougher chips produced by such alloys. When selecting cutting parameters, favour moderate depths of cut with controlled feed to exploit the insert’s edge stability; this will deliver predictable wear patterns and consistent surface integrity over extended runs.
