WCGT040202-X15 WAK15 Trigon 80° indexable insert for aluminium — Walter Tools

The WCGT040202-X15 WAK15 is an indexable insert engineered for drilling and boring operations in aluminium and non-ferrous metals, combining a trigon cutting form with a specialised chipformer for controlled evacuation

• Trigon 80° cutting form
• WAK15 uncoated carbide grade
• X15 chipbreaker for non-ferrous metals
• 7° clearance angle for reduced rubbing

Faster, cleaner aluminium machining through optimised geometry

The combination of a Trigon 80° profile and an uncoated carbide substrate delivers a consistent, sharp cutting edge that is especially effective when machining aluminium and similar alloys. The insert’s geometry reduces the tendency for material to stick, so feed rates can be optimised while maintaining surface integrity. This results in shorter cycle times and fewer interruptions for rework, making the component suitable where productivity and part quality are priorities. The construction supports repeatable performance in serial production.

Precise chip control and improved surface quality

A dedicated X15 chipbreaker offers predictable chip formation and evacuation during drilling and boring, lowering the risk of chip packing and surface scoring. The 0.2 mm nose radius produces a controlled cutting contact that balances sharpness and edge strength, which benefits final surface finish. Combined with the 7° clearance angle, the design minimises rubbing and heat build-up at the flank, promoting dimensional accuracy and extending the usable life of the cutting edge under normal operating conditions.

Simple integration into existing tool systems and stable results

The insert is supplied in the Walter N-Sortensystem series and is compatible with standard toolholders that accept the WCGT shape and size code. Its consistent tolerances and the WAK15 grade enable reliable seat fit and repeatable run-out characteristics, which reduces set-up time and inspection demands. Given its role in non-ferrous machining, the insert supports process stability and eases tool selection for mixed-production environments where aluminium parts form a significant share.

Material suitability and practical application notes

Classified for group N (non-ferrous metals), the insert is intended for aluminium, copper and light alloys; the WAK15 grade is uncoated to avoid built-up edge commonly seen with sticky materials. In practice, light to moderate cutting fluids or air cooling are often sufficient; high-pressure coolant is rarely necessary for typical aluminium work. When used with the appropriate toolholder and cutting parameters, the insert contributes to consistent chip control and reduced burr formation, supporting downstream assembly or finishing operations.

FAQ

What materials is this insert best suited for? The WCGT040202-X15 WAK15 is specified for aluminium and other non-ferrous metals; the WAK15 grade is an uncoated carbide designed to reduce built-up edge on these materials.

How does the X15 chipbreaker affect performance? The X15 chipbreaker promotes predictable chip formation and evacuation, improving process stability during drilling and boring and helping to protect the work surface from scoring.

Can the insert be used in standard toolholders for WCGT inserts? Yes, the insert follows the WCGT form and size code, allowing integration into compatible toolholders that accept Trigon 80° inserts with the corresponding seat geometry.

Why choose an uncoated grade for aluminium? An uncoated carbide grade like WAK15 reduces the risk of chip adhesion that can occur with coatings; this keeps the cutting edge sharp and maintains surface quality when machining sticky, low-alloy materials.

What role does the 0.2 mm nose radius play? The 0.2 mm nose radius balances edge sharpness and strength, enabling higher-quality surface finishes while retaining sufficient edge stability for common drilling and boring feeds.
