CCMT120404-E47 WPP20G Drill/Boring Indexable Insert (for Steel) – Walter Tools

The CCMT120404-E47 WPP20G is a rhombic 80° coated-carbide insert engineered for drilling and boring operations in steel, delivering stable chip control and robust edge performance

• Tiger·tec Gold coated carbide for long life
• Optimised E47 chipbreaker for consistent chips
• Rhombic 80° form with 0.4 mm corner radius
• 7° clearance angle for reliable cutting geometry

Boosted productivity through coated-carbide technology

The CCMT120404-E47 WPP20G combines Tiger·tec Gold coating with a coated-carbide matrix to extend tool life and maintain cutting edge stability under typical steel machining temperatures. Designed for the ISO P material group, the grade balances wear resistance and toughness so that operations run longer between indexings. This results in lower overall tooling cost per part and fewer interruptions to the process, supporting higher throughput in batch and continuous machining environments.

Predictable chip formation for safer, faster cycles

An E47 chipbreaker tuned to the insert geometry promotes uniform chip formation and improved evacuation during drilling and boring. Predictable chips reduce the risk of recutting and tool damage, improving surface integrity and dimensional repeatability. The controlled chip flow also contributes to shorter cycle times on automated machines, adding process security where consistent part quality is required.

Mechanical geometry for accuracy and edge strength

The rhombic 80° insert form with a 0.4 mm corner radius and 7° clearance angle provides a robust cutting edge and dependable seating in standard toolholders. The nominal insert size 12 and thickness code 04 offer rigidity for bore enlargement and through-hole operations while keeping cutting forces manageable. This geometry supports stable cutting behaviour, helping to maintain tolerances and extend indexable insert life in repetitive applications.

Application focus and material suitability

Specifically developed for steel machining, the WPP20G grade offers a universal wear profile suitable for a wide range of unalloyed and alloyed steels. Its application range addresses common workshop and production needs where a balance of economy and performance is expected. The combination of coating and chipbreaker makes it a practical choice for engineers seeking repeatable results in standard steel-turning and boring tasks.

FAQ

Is this insert suitable for alloyed steels?
The CCMT120404-E47 WPP20G grade is intended for the ISO P group and is suitable for both unalloyed and many alloyed steels, offering a balanced wear and toughness profile for typical steel machining.

What benefit does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating on the WPP20G grade increases thermal stability and wear resistance, helping the insert to maintain cutting-edge condition over longer periods in steel applications.

How does the E47 chipbreaker affect performance?
The E47 chipbreaker creates predictable chip shapes and supports efficient evacuation during drilling and boring, which reduces the likelihood of recutting and improves surface quality.

Can the CCMT120404-E47 fit standard toolholders for CCMT inserts?
The CCMT120404-E47 conforms to standard CCMT geometry and will seat in compatible toolholders designed for CCMT-size inserts; correct clamping and orientation should be observed.

What size is the inscribed circle and what is the typical corner radius?
The insert uses an inscribed circle size of 12 and features a 0.4 mm corner radius to balance edge strength and finish in bore enlargement work.
