DCGW070204TM-2 WBH20 indexable turning insert, rhombic 55° – Walter Tools

DCGW070204TM-2 WBH20 is an indexable turning insert engineered for hard machining tasks, primarily the precision turning of hardened and pre-hardened steels.

• CBN grade WBH20 for hard turning
• Rhombic 55° geometry for versatile approach
• 7° clearance angle for secure chip control
• 0.4 mm corner radius for controlled finishing

Maximise process reliability with wear-resistant CBN performance

The DCGW070204TM-2 WBH20 insert is built around a CBN cutting grade that is optimised for demanding hard-turning operations. The cutting material offers high wear resistance under elevated contact temperatures and abrasive conditions, which translates into longer tool life and fewer index changes. This reliability reduces unplanned downtime and supports stable cycle times on production lines where consistency is critical. The combination of grade and geometry supports repeatable results across batches.

Achieve consistent surface quality through defined geometry

The rhombic 55° form and 7° clearance angle are designed to deliver a balanced cutting action with reduced flank rubbing and improved access to workpiece contours. The 0.4 mm corner radius provides a compromise between edge strength and the ability to produce fine surface finishes, while the integrated chipbreaker 2 promotes predictable chip formation and evacuation. Together, these characteristics support controlled finishes in hard materials without excessive cutting forces, making the insert suitable for finishing and semi-finishing passes where surface integrity matters.

Clear material suitability and focused applications

This CBN insert is targeted primarily at hardened steels (ISO H) and is also suitable for pre-hardened steel applications where elevated hardness requires a wear-resistant cutting material. The WBH20 grade is engineered for hard machining tasks that demand stable edge life and repeatable dimensional control. Selection of this grade helps to maintain consistent tolerances and surface conditions when machining components subjected to high contact stresses, such as hardened shafts, bearing seats or heat-treated components.

Easy identification and practical selection for production setups

Specified under the ISO-style designation DCGW070204TM-2 and supplied by Walter Tools, this insert allows for straightforward catalogue matching and tooling planning. The clear coding makes holder selection and inventory control simpler for production engineers. For operators unfamiliar with CBN grades or with particular workpiece alloys, application advice is available to align cutting data and insert choice with the required productivity and surface specifications, supporting a smooth integration into existing machining processes.
