CCGW09T304TS-2 WBK20 – Turning/boring indexable insert with CBN grade and 0.4 mm nose radius | Walter Tools

The CCGW09T304TS-2 WBK20 is a rhombic 80° turning and boring indexable insert engineered for high-wear, hardened-material applications where long tool life and consistent finishes are required.

• CBN grade WBK20 for high wear resistance
• 0.4 mm nose radius for precise surface finishes
• Rhombic 80° geometry for versatile turning tasks
• 7° clearance angle to reduce rubbing and cutting forces

Durable CBN grade for hard and abrasive workpieces

The use of CBN in the WBK20 grade provides exceptional wear resistance and thermal stability compared with conventional carbide grades. This makes the insert particularly suited to machining hardened steels and other high-wear materials where edge retention and process stability are essential. By selecting a CBN grade, machinists achieve longer tool life and fewer index changes, which reduces downtime and keeps production running more predictably. Material suitability should be checked against the manufacturer’s product matrix to ensure optimal results.

Geometry that improves finish and dimensional control

The Rhombus 80° form combined with a 0.4 mm nose radius balances accessibility in bore and face operations with the ability to produce tight radii and repeatable surface quality. The modest radius supports finer finishes without sacrificing strength at the cutting edge. A 7° clearance angle reduces contact between flank and workpiece, lowering friction and the risk of built-up edge; the integrated chipbreaker 2 promotes consistent chip formation for safer swarf evacuation and reduced risk of interruption in automated cycles.

Process advantages that cut operating costs

Using a CBN insert like this one typically leads to fewer tool changes and more consistent part quality over long production runs, yielding a better cost-per-part outcome in demanding applications. The insert’s tolerance class G and T3 thickness provide mechanical stability in standard toolholders, helping to maintain repeatability across batches. For best performance, feed and speed parameters should be set in line with the Walter Tools recommendations and adapted to the specific workpiece material and machine rigidity.

Practical compatibility and handling notes

The insert is an indexable turning/boring grade available in size 09 and bears the designation CCGW09T304TS-2 for direct reference when selecting toolholders or replacements. Ensure the chosen toolholder accepts the CCGW format and that clamping faces are clean and undamaged to preserve repeatability. Hard turning and finishing on hardened components will benefit from the insert’s stable cutting edge; if uncertainty remains regarding a specific alloy or application, technical consultation is advisable before series production.

FAQ

What materials is this insert designed for?
The CCGW09T304TS-2 WBK20 uses a CBN grade intended for hard, high-wear materials such as hardened steels; suitability for specific alloys or cast materials should be verified against Walter Tools’ product matrix.

How does the 0.4 mm nose radius affect surface finish?
A 0.4 mm nose radius provides a balance between strength and finish capability, enabling finer surface quality while maintaining edge stability during turning and boring.

Is the insert suitable for finishing and roughing?
The geometry and CBN grade favour finishing and hard turning; for heavy roughing on softer materials, a different grade or geometry may be more economical.

How important is toolholder rigidity with this insert?
High toolholder rigidity is crucial to exploit the CBN grade’s advantages and to achieve consistent surface quality and tool life with this insert.

Can the insert be used in turning and boring tool systems?
Yes. The rhombic 80° form and the CCGW format are designed for compatibility with standard turning and boring holders that accept this insert type.
