CPGT050202-X15 WAK15 — Drill and Boring Indexable Insert for Aluminium | Walter Tools

The CPGT050202-X15 WAK15 is a rhombic 80° indexable insert engineered for drilling and boring operations in aluminium and other non‑ferrous metals, offering controlled chip formation and predictable cutting performance.

Uncoated carbide grade WAK15
Optimised for aluminium and non‑ferrous metals
Rhombic 80° geometry for versatile use
11° clearance with 0.2 mm corner radius

Consistent chip control for aluminium machining

Designed around the WAK15 carbide grade and an X15 chipbreaker, this insert prioritises clean chip formation when machining aluminium and similar non‑ferrous materials. The uncoated carbide substrate gives a sharp, low‑adhesion cutting edge that reduces built‑up edge and the need for frequent regrinds. For engineers looking to reduce scrap and improve surface integrity, the result is a more reliable process window: shorter cycle variability, fewer tool changes and a repeatable finish quality that supports downstream operations.

Geometry and clearance that improve stability and tool life

The Rhombic 80° shape combined with an 11° clearance angle and a 0.2 mm corner radius balances cutting edge strength with accessibility in recessed or stepped features. This geometry delivers lateral stability during drilling and bore enlargements while keeping the cutting edge exposed enough to evacuate chips effectively. The insert’s form factor and tolerance class G make it suitable for indexed toolholders where repeatable seating and positioning are essential for consistent concentricity and bore tolerance control.

Tailored for non‑ferrous ISO group N and simple material selection

Classified for ISO group N, this insert is explicitly intended for aluminium and non‑ferrous metals; tool selection is therefore simplified for mixed production runs that prioritise these materials. Using an insert from the Walter N‑Sortensystem reduces trial‑and‑error in grade choice and supports predictable results across alloy variations. The insert format CPGT050202‑X15 and the X15 chipbreaker enable process engineers to match cutting data quickly and exploit toolholder inventories without extensive reprogramming.

Practical handling and integration in production

As an indexable insert, this grade reduces downtime by allowing fast indexing and consistent reset after regrind or replacement. The standardised designation and series support straightforward ordering and stock management. Combined with Walter Tools’ manufacturing standards, the insert offers a pragmatic route to improving throughput on machines used for light alloy components, where chip control and surface quality directly affect assembly fit‑up and cosmetic requirements.

FAQ

What materials is this insert suitable for?
The CPGT050202‑X15 WAK15 insert from Walter Tools is intended for aluminium and other non‑ferrous metals, corresponding to ISO group N.

Which insert geometry ensures stability for boring operations?
The rhombic 80° geometry with an 11° clearance and 0.2 mm corner radius offers stability and chip control, making the CPGT050202‑X15 WAK15 appropriate for a range of drilling and boring tasks in non‑ferrous materials.

Is the WAK15 grade coated or uncoated?
The WAK15 grade used in this insert is uncoated carbide, selected to provide a sharp edge and reduced adhesion when cutting aluminium.

How does the X15 chipbreaker affect machining?
The X15 chipbreaker promotes short, controllable chips and helps avoid material build‑up on the cutting edge, improving surface finish and reducing interruptions during runs with the CPGT050202‑X15 WAK15.

How is the insert identified for ordering and inventory?
Order and stock by the SKU CPGT050202‑X15‑WAK15‑WALTER and the designation CPGT050202‑X15 WAK15; both appear on the tool documentation and packaging.
