WCGT040204-X5 WAK15 — Indexable drilling/reaming insert for aluminium (Walter Tools)

WCGT040204-X5 WAK15 is a trigon‑form indexable insert designed for drilling and reaming operations in aluminium and other non‑ferrous metals, supplied within the Walter N‑Series.

• Uncoated carbide grade for non‑ferrous metals
• Trigon 80° form for high axial stability
• X5 chipbreaker for reliable chip control
• 7° clearance and 0.4 mm corner radius

Consistent machining performance for aluminium work

The WAK15 uncoated carbide grade is optimised for aluminium and other non‑ferrous materials, delivering sharp cutting edges and low adhesion during high‑feed operations. The combination of a Trigon 80° insert form and the X5 chipbreaker reduces build‑up on the cutting edge and promotes consistent chip flow, which directly improves surface quality and reduces downtime for cleaning. These traits make the insert particularly suitable for cyclic drilling and reaming where repeatable outcomes and short cycle times are required.

Geometry that extends edge life and process reliability

A 7° clearance angle and a 0.4 mm corner radius balance edge strength with low cutting forces, lowering the risk of material welding and premature edge wear. The trigon profile provides a larger contact area for axial loads, improving tool stability during plunge operations. For machinists unfamiliar with technical terms: the clearance angle keeps the insert from rubbing on the workpiece, while the corner radius helps distribute cutting stresses to avoid chipping. Together, these geometric choices translate into longer tool life and fewer tool changes per shift.

Easy integration into standard indexable drilling systems

The insert is produced to the Walter N‑Series specifications and is identified as WCGT040204-X5 WAK15, making it straightforward to match with compatible toolholders designed for trigon 80° inserts. The size and thickness codes follow industry conventions, enabling quick selection in tool lists and CAM routines. Integration is simple: the insert’s chipbreaker and uncoated surface reduce the need for aggressive coolant strategies in many aluminium applications, supporting efficient retrofit into existing machining cells without process upheaval.

Production benefits from a reputable cutting tool partner

Choosing a Walter Tools insert combines robust tool geometry with the manufacturer’s focus on process stability and surface quality. The uncoated carbide construction delivers predictable wear behaviour in soft, sticky materials like aluminium, while the X5 chipbreaker assists with continuous chip evacuation. For production managers, this means fewer interruptions, improved first‑pass yield and more consistent part tolerances across batches — an economic benefit that supports throughput and quality goals.

FAQ

What materials is the insert optimised for?
The WCGT040204-X5 WAK15 is optimised for aluminium and other non‑ferrous metals, using the WAK15 uncoated carbide grade to reduce adhesion and improve surface finish.

How does the X5 chipbreaker affect production?
The X5 chipbreaker on this insert promotes short, controllable chips and reliable evacuation, which reduces stoppages and supports consistent cycle times in aluminium drilling applications.

Which toolholders are compatible with the insert form?
Trigon 80° toolholders designed for the Walter N‑Series accept this insert form; the geometry and coding match standard indexable drilling/reaming tool systems.

Is this insert coated or uncoated, and why does that matter?
This insert is uncoated carbide (WAK15). For aluminium and sticky non‑ferrous materials, uncoated grades minimise built‑up edge and improve cutting behaviour compared with many coated grades.

Can the insert be used for heavy interrupted cuts?
The trigon geometry and 0.4 mm corner radius increase edge robustness, so moderate interruptions are manageable; for severe interruptions, select a grade and radius matched to the application.
