WCGT020102-X5 WAK15 — Drilling/Reaming Indexable Insert, Trigon 80°, Chipbreaker X5 (Walter Tools)

WCGT020102-X5 WAK15 is a trigon 80° indexable insert developed for drilling and bore-enlarging operations in aluminium and other non-ferrous metals.

• Trigon 80° geometry for stable cutting
• Uncoated carbide grade WAK15 for aluminium
• X5 chipbreaker for predictable chip control
• 7° clearance angle and 0.2 mm corner radius

Precision chip control for non‑ferrous machining

The WCGT020102-X5 WAK15 insert is specifically engineered for machining aluminium and similar non‑ferrous materials. The uncoated carbide composition of the WAK15 grade ensures a sharp cutting edge that reduces material adhesion and built‑up edge formation, common challenges when working with soft, gummy alloys. As a result, the insert delivers consistent chip formation and repeatable bore quality across batch production. This leads to predictable tool life and fewer interruptions for rework or tool changes, supporting throughput requirements in industrial environments.

Geometry that improves process stability and hole quality

The trigon 80° profile and a 7° clearance deliver a balance between strength and accessibility to the cutting edge. The defined corner radius 0.2 mm combines edge strength with the ability to produce clean hole walls and controlled surface finish. These geometric choices reduce vibration during drilling and reaming, improving concentricity and bore tolerance control. In practical terms, the insert’s shape helps maintain tool stability in guided drilling applications and contributes to lower scrap rates when machining delicate aluminium components.

Chip management and series benefits for efficient production

The X5 chipbreaker is designed to fragment and evacuate chips reliably during drilling and bore enlargement, which lowers the risk of recutting and thermal build‑up in the cutting zone. Good chip control also reduces the need for complex coolant strategies in many aluminium applications, enabling leaner processes. As part of the Walter N‑Series, the insert benefits from a coordinated system approach: grade geometry and chipbreaker are matched to support consistent cutting behaviour, making integration into existing toolholders and processes straightforward and efficient.

FAQ

What materials is this insert suitable for?
The WCGT020102-X5 WAK15 insert is optimised for aluminium and other non‑ferrous metals; the WAK15 uncoated carbide grade minimises material adhesion during cutting.

Why is an uncoated grade used for aluminium machining?
Uncoated carbide such as WAK15 provides a very sharp edge and lower chemical affinity with aluminium, reducing the risk of built‑up edge and improving surface finish during drilling and reaming.

How does the Trigon 80° shape affect drilling performance?
A Trigon 80° geometry offers a stable cutting platform with an optimised cutting angle that improves hole quality and reduces vibration compared with more acute profiles.

What benefit does the X5 chipbreaker deliver in production?
The X5 chipbreaker promotes predictable chip fragmentation and evacuation, which enhances process stability, lowers recutting risk and supports higher productivity in serial machining.

Which system series does this insert belong to and why does that matter?
This insert is part of the Walter N-Sortensystem, which ensures matched geometries and chip control for consistent, repeatable cutting performance in production environments.
