CCMT120408-E47 WPP20S — Drill/bore indexable insert, Tiger·tec Silver (Walter Tools)

The CCMT120408-E47 WPP20S is a rhombic 80° indexable insert engineered for drilling and bore‑enlarging operations in steel machining applications.

• Tiger·tec Silver coating for long tool life
• Grade WPP20S optimised for steel machining
• Rhombic 80° shape for versatile indexing
• 0.8 mm corner radius for stable edge retention

Boosted productivity through coating and grade

The combination of the Tiger·tec Silver coating and the WPP20S carbide grade provides a measurable gain in process stability for steel (ISO group P). The coating reduces flank wear and improves thermal resistance, which in turn extends effective tool life and reduces tool change frequency. For production environments this translates into fewer interruptions and a more predictable machining cycle; chip formation remains consistent under typical cutting temperatures, supporting higher metal removal rates without sacrificing component quality.

Geometry and edge design for reliable cutting

A rhombic 80° geometry together with a 0.8 mm corner radius balances strength and accessibility at the cutting edge. This geometry allows multiple index positions, improving insert economy, while the modest corner radius offers a compromise between edge robustness and achievable surface finish. The E47 chipbreaker is designed to promote controlled chip segmentation when cutting steels, easing chip evacuation from deep holes and bore cores and reducing the risk of built‑up edge formation in demanding through‑hole or enlarging passes.

Practical application notes and process guidance

This insert is intended for drilling and bore‑enlarging tasks in a variety of steel grades. The WPP20S grade is formulated for typical steel heat generation and chip behaviour; it is therefore suited to general finishing and medium roughing operations where predictable wear and repeatable results are required. For less experienced operators: chipbreaker types influence chip flow, and a correctly matched feed and speed will avoid premature wear. Specifications such as corner radius and clearance angle determine the achievable surface quality and should be selected to match the workpiece tolerance and machine rigidity.

Process reliability and economic benefits

Using a coated, grade‑matched insert reduces the overall cost per hole by extending insert life and lowering scrap risk from tool failure. The controlled chip behaviour from the E47 breaker reduces downtime for chip clearing and minimises manual intervention, improving throughput. Over a production run, the combination of reliable edge retention and consistent chip control supports reproducible component finishes and predictable maintenance intervals, delivering operational efficiency and lower unit costs.
