DCGW11T308TM-2 WBH20C turning insert by Walter Tools — CBN grade for hard turning, rhombic 55° form

DCGW11T308TM-2 WBH20C is an indexable turning insert designed for stable, long-life performance when machining hardened materials in demanding production environments.

*CBN cutting grade WBH20C for hard-turning applications
*7° relief angle for secure cutting engagement
*Rhombic 55° insert form for versatile turning
*0.8 mm corner radius for consistent edge life

Predictable hard-turning with CBN for higher uptime

The insert uses the WBH20C coated CBN grade, engineered for sustained performance in hard and highly abrasive materials. This results in reduced flank wear and longer intervals between tool changes, which directly improves machine uptime and lowers unit manufacturing costs. For shops processing hardened steels or pre-hardened components, the combination of a wear-resistant cutting material and robust geometry ensures repeatable part quality and a steady production flow.

Geometry and edge design that control chips and surface finish

A rhombic 55° shape combined with a 7° relief angle and a 0.8 mm corner radius provides a balance between cutting strength and surface integrity. The specific chipbreaker 2 profile promotes short, controllable chips in interrupted and continuous cuts, reducing the likelihood of edge build-up. These geometric choices translate into stable cutting forces and an improved surface finish on turned components, helping to meet tight tolerances with fewer reworks.

Practical benefits for tool management and process security

The insert is produced to tolerance class G and supplied in the Walter CBN / hard-material series, allowing consistent indexing and predictable performance across tool sets. The T3 thickness and size 11 designation suit many standard turning toolholders, facilitating quick replacement and simple inventory handling. Given its design focus on hardened and pre-hardened steels, the insert is particularly valuable for sectors where repeatability and tool life are critical, such as precision engineering and high-volume hard-machining operations.
