CPGT050202-X5 WAK15 — Drilling/Boring indexable insert (Rhombic 80°), Walter Tools

A CPGT050202-X5 WAK15 drilling/boring indexable insert engineered for productive machining of aluminium and other non‑ferrous metals, featuring a positive relief and a fine corner radius for clean finishing.

• Rhombic 80° insert geometry
• 11° relief angle for positive cutting
• 0.2 mm corner radius for fine finishing
• WAK15 uncoated carbide for aluminium

Precise geometry that improves component quality

The Rhombic 80° shape combined with an 11° relief produces a positive cutting action that reduces cutting forces and improves chip flow when working with aluminium. This geometry supports consistent tool engagement in bore and drilling operations, resulting in a more uniform hole quality and reduced tendency for material build‑up. The small 0.2 mm corner radius helps to deliver a smoother surface finish without sacrificing edge strength, so the insert contributes directly to tighter tolerance achievement and fewer secondary operations.

Material grade and chip control for non‑ferrous machining

The WAK15 is an uncoated carbide grade tailored for non‑ferrous metals and aluminium; its composition and the X5 chipbreaker are optimised to prevent material adhesion and to form short, controllable chips. In practice this means improved process reliability and less downtime for cleaning or rework. For shops that handle high volumes of aluminium components, the combination of sharp cutting edge and dedicated chipformer reduces cycle times and lowers scrap rates, delivering measurable productivity gains.

Production benefits: economy and handling

An indexable solution such as this insert reduces tool change complexity and keeps inventory simple, as insert geometry and grade are standardised across the Walter N‑Sortensystem series. The positive cutting geometry lowers feed forces, allowing stable operation at higher feed rates in many cases; this leads to a favourable cost‑per‑hole metric and a quick return on tooling investment. The insert’s dimensions and standard fitting make it compatible with a wide range of holders used in common drilling and boring applications.

Compatibility, setup and safe use

The insert is supplied in the CPGT050202‑X5 form factor and fits holders designed for Rhombic 80° inserts; its positive relief and dedicated chipbreaker ease setting up feeds and speeds for aluminium alloys and similar non‑ferrous materials. When programming and selecting parameters, prioritise reduced cutting speeds compared with ferrous machining and ensure adequate coolant or air blast to assist chip evacuation. The clear designation of grade and geometry simplifies tooling decisions and tool management on the shop floor.

FAQ

What materials is this insert suitable for?
The CPGT050202‑X5 WAK15 insert is designed primarily for aluminium and other non‑ferrous metals; the WAK15 uncoated carbide grade and X5 chipbreaker reduce adhesion and improve chip control.

Can this insert be used in standard bore holders?
Yes, the insert’s Rhombic 80° form and CPGT050202‑X5 designation match common holders for Rhombic inserts used in drilling and boring operations.

How does the 0.2 mm corner radius affect finish?
A 0.2 mm corner radius provides a balance between edge strength and surface quality, enabling fine finishing while maintaining resistance to edge chipping in aluminium machining.

Is the grade coated or uncoated, and why does that matter?
WAK15 is an uncoated carbide grade; for aluminium machining, uncoated grades with sharp edges often reduce built‑up edge and adhesion compared with some coated grades.

Where can one get parameter recommendations for this insert?
Parameter guidelines and application advice are available from Metav Werkzeuge; the CPGT050202‑X5 WAK15 designation simplifies selection for the relevant holder and workpiece material.
