TCGW110204TM-3 WBH20C – drilling/reaming and turning indexable insert, coated CBN for hardened steel, triangle 60° (Walter Tools)

The TCGW110204TM-3 WBH20C is a coated CBN indexable insert engineered for hard machining and finishing applications on hardened steels, offering stable cutting performance where high wear resistance is required.

• Coated CBN grade WBH20C for hard materials
• Triangle 60° geometry, 0.4 mm corner radius
• 7° relief angle for stable cutting
• Chipbreaker 3 for consistent chip control

Delivering durable cutting performance for hardened steels

The insert uses a coated CBN grade developed to resist abrasive wear during the machining of hardened materials. Coated cubic boron nitride is designed specifically for high-hardness environments; it maintains a stable cutting edge where conventional carbides would wear rapidly. This means fewer tool changes and more predictable batch processing when handling components from the ISO H group, where hardness and cutting forces are elevated. The result is longer effective tool life and reduced unscheduled downtime.

Geometry and edge form for repeatable accuracy

A triangle 60° shape with a 0.4 mm corner radius balances strength and the ability to achieve fine external profiles. The small corner radius supports finishing passes with an emphasis on surface integrity, while the 7° relief angle reduces friction behind the cutting edge to minimise rubbing and built-up edge. The integrated chipbreaker 3 aids controlled chip formation, making swarf evacuation more reliable and helping to protect both the insert edge and the finished component from damage during hard turning operations.

Application scope and production benefits

Belonging to the Walter CBN series and designated WBH20C, this insert targets hard machining tasks such as finishing or semi-finishing of hardened steels and pre-hardened parts. The specification includes an insert size 11 and thickness 02, which suit a range of toolholders and turning programmes while allowing for stable clamping and low-vibration cutting. In practice, the insert contributes to higher process reliability and consistent surface quality, which supports cost-efficiency across medium and large production runs.

Practical integration into the workshop workflow

The indexable design simplifies replacement routines and enables rapid return to dimensional tolerance after a change. As part of a coherent tooling system, the insert supports standardised set-ups and repeatable results, contributing to predictable cycle times. When combined with the correct cutting data for hardened steels and a suitable toolholder, this grade offers measurable reductions in tooling consumption and rework — a direct benefit to throughput and operating costs in hard-turning applications.

FAQ

What materials is this insert suitable for?
The WBH20C grade is formulated for the ISO H group; the TCGW110204TM-3 WBH20C excels on hardened steels and pre-hardened components.

How does the triangle 60° geometry affect machining?
Triangle 60° geometry provides three cutting edges per insert and a compact profile that supports both strength and fine finishing when using the WBH20C CBN grade.

What advantage does the 0.4 mm corner radius deliver?
A 0.4 mm corner radius improves edge robustness while enabling good surface finish, making the insert suitable for finishing passes in hard machining.

Is chip control handled by the insert design?
Yes, the integrated chipbreaker 3 promotes predictable chip formation, which helps maintain a stable process and protects the cutting edge during hard turning.

How does the CBN coating impact tool life?
Coated CBN offers significantly higher wear resistance in hard-material applications, increasing the service life of the insert and reducing the frequency of tool changes.
