CPGT050204-X5 WAK15 — drilling/boring indexable insert by Walter Tools (Rhombic 80°, 0.4 mm radius)

CPGT050204-X5 WAK15 is an indexable insert designed for drilling and boring in aluminium and other non‑ferrous metals, offering a precise cutting geometry and a chipbreaker matched to soft metal machining.

WAK15 uncoated carbide for aluminium machining
Rhombic 80° insert form
0.4 mm corner radius for finishing
11° clearance angle for smooth cutting
X5 chipbreaker for controlled chips

Consistent, sharp grade for non‑ferrous materials

The WAK15 grade is an uncoated cemented carbide developed for aluminium and other non‑ferrous alloys, providing consistently sharp cutting edges that reduce material adhesion and minimise burr formation. This results in improved hole surface quality and fewer rework cycles. For shops processing high volumes of soft metals, the grade’s geometry supports stable cutting conditions and predictable tool life, helping to keep cycle times low and scrap rates down.

Geometry tailored to precise hole finishing

The rhombic 80° form combined with a 0.4 mm corner radius and an 11° clearance angle gives a balance between edge strength and cutting precision. The acute rhombic shape enables accurate entry and stable guidance in bore processes, while the small corner radius promotes fine surface finishes on the bore wall. These geometric choices mean fewer passes are required to reach tolerance, improving throughput without sacrificing finish quality.

Reliable chip control and process stability

Equipped with the X5 chipbreaker, the insert is engineered to break and evacuate chips efficiently when machining aluminium and similar materials. Better chip control reduces the risk of re-cutting and tool crashes, contributing to higher process reliability and less machine downtime. The insert’s placement within the Walter N‑grade system signals an application focus on non‑ferrous machining, making it straightforward to select matching grades for related operations.

Practical fit for workshop workflows

This insert is suitable for drilling and boring applications where sharpness and clean chip formation are priorities. Its standard size code and thickness enable easy toolholder compatibility and simple stocking alongside other indexable cutting tools. For shops moving between different non‑ferrous alloys, the combination of grade and chipbreaker offers versatility while retaining the advantages of a purpose‑built insert.
