TCGW110204TM-3 WBH30 – Indexable CBN turning insert for hard turning | Walter Tools

The TCGW110204TM-3 WBH30 is an indexable CBN turning insert engineered for hard turning and finishing of hardened steels and similar high-wear workpieces.

• CBN grade WBH30 for hard turning
• 7° relief angle for stable cutting
• 0.4 mm corner radius for edge strength
• Triangular 60° insert for versatile indexing

Consistent performance on hardened steels

The combination of CBN cutting material and the WBH30 grade delivers consistent wear resistance for demanding hard machining tasks. CBN is a superabrasive optimised for elevated temperatures and abrasive contact, which reduces flank wear during continuous cutting. This insert is designed to maintain a steady cutting edge under heavy thermal and mechanical stress, leading to predictable tool life and fewer interruptions in production. The focus here is on efficiency and repeatability when machining hardened steels (H).

Geometry that extends productive time between changes

A 7° relief angle and a 0.4 mm corner radius create a balance between cutting stability and surface finish. The modest relief reduces cutting forces and supports an even load distribution on the CBN layer, while the corner radius helps prevent premature chipping at the edge. These geometrical choices contribute directly to longer tool life and improved component quality, reducing the frequency of tool changes and supporting continuous, high-yield machining operations.

Indexable triangle shape for quick reconditioning and flexibility

The triangular 60° form provides multiple usable edges per insert and simplifies indexing routines on turning toolholders. With a nominal size of 11 and thickness designation 02, the insert suits toolholders that accept this family of triangular inserts and allows cost-effective use of each part. Indexable inserts speed up changeover and reduce tooling inventory compared with single-purpose solid tools; this geometry in particular supports both roughing and finishing passes in hard turning sequences when set up with suitable cutting parameters.

Process benefits, predictability and application scope

Intended primarily for hard turning applications, the insert supports machining strategies where stability and reproducible results are required. The CBN grade performs well in finish turning and some light semi-finishing of hardened steels, and it is appropriate where wear resistance is a priority. Integrating this insert into a controlled process yields measurable benefits: fewer rejects due to edge deterioration, more consistent surface quality and a reduction in unplanned downtime. For best results, cutting data should be adapted to machine rigidity and clamping conditions.
