CPGT050204‑X15 WAK15 — drilling/reaming indexable insert, rhombic 80° | 11° clearance — Walter Tools

The CPGT050204‑X15 WAK15 is a drilling and boring indexable insert engineered for high‑efficiency machining of aluminium and other non‑ferrous materials, combining a sharp cutting geometry with an uncoated cemented carbide grade.

• Uncoated solid carbide WAK15 grade
• Optimised for aluminium and non‑ferrous metals
• Rhombic 80° geometry for precise entry
• 11° clearance and 0.4 mm corner radius

Reliable chip control and consistent results for non‑ferrous machining

The insert’s geometry and grade deliver consistent chip formation when working with aluminium and similar alloys. As an uncoated cemented carbide grade, WAK15 provides a very sharp cutting edge that reduces material adhesion and built‑up edge — a common challenge with soft, ductile materials. The combination of the X15 chipformer and the rhombic 80° shape focuses on generating short, controllable chips and minimising downtime for chip removal, which supports higher machine utilisation and fewer interruptions in production.

Geometry that improves hole quality and reduces secondary operations

The rhombic 80° form with a 0.4 mm corner radius and 11° clearance helps to secure consistent hole entry and wall finish. This geometry translates into fewer burrs and less manual deburring after drilling or boring operations. By reducing the need for secondary finishing, the component flow is streamlined and cycle times are shortened — a clear efficiency gain for batch production and high‑mix environments. The insert’s definition of relief and corner rounding also supports repeatability across multiple tool changes.

Material selection aimed at productivity and tool life

Choosing an uncoated WAK15 grade means the cutting edge remains sharp and resistant to the adhesive tendencies of non‑ferrous alloys. While coated grades are beneficial for higher temperatures or abrasive materials, the WAK15 composition is tuned for low cutting resistance and stable cutting in soft metals, promoting longer tool life per cutting edge in these applications. The Walter N‑grade system identification underlines suitability for ISO group N materials, helping process planners match the insert to the correct workpiece family without lengthy trials.

Integration into production and practical benefits for workshops

The insert’s standardised ISO designation and compact dimensions make it straightforward to integrate into common holder systems and tool assemblies. This compatibility reduces set‑up time and simplifies inventory management. For production planners, the balance of precision, chip control, and the proven Walter manufacturing standards offers predictable performance and easier process qualification. Where repeatability and surface quality matter, this insert supports stable machining regimes and reduces scrap rates.

FAQ

Which materials are best suited for this insert?
The CPGT050204‑X15 WAK15 insert is designed for aluminium and other non‑ferrous metals, following the ISO N classification and the Walter N‑Sortensystem recommendations.

Why choose an uncoated WAK15 grade for aluminium?
The uncoated WAK15 grade provides a very sharp cutting edge and low adhesion characteristics, which reduces built‑up edge and improves surface quality when machining soft, ductile alloys.

How does the rhombic 80° geometry affect drilling performance?
The rhombic 80° form supports controlled entry and stable drilling forces; combined with the 0.4 mm corner radius and 11° clearance, it helps to reduce burr formation and the need for secondary finishing.

Can this insert be used with standard holders and drills?
Yes — the ISO designation and plate dimensions of the CPGT050204‑X15 WAK15 permit integration into common indexable insert holders and tooling systems, simplifying tool changeover and inventory.
