SPGT1204AEN-K88 SPGT1204AEN-K88 WXN15 — Indexable milling insert, 11° relief, square 90°, Walter Tools (for non‑ferrous metals)

The SPGT1204AEN-K88 WXN15 is a square indexable milling insert engineered for sharp, uncoated cutting of non‑ferrous metals such as aluminium, copper and brass, combining the Walter N‑series geometry with a dedicated K88 chipbreaker for consistent chip control.

• Sharp uncoated carbide grade WXN15
• Square 90° geometry for stable cuts
• K88 chipbreaker for improved chip control
• 11° relief angle for smooth engagement

Faster, cleaner machining of non‑ferrous materials

The WXN15 grade is an uncoated carbide designed specifically for N‑group materials, which means it delivers a very sharp cutting edge and low chemical affinity to aluminium and similar alloys. This sharpness reduces the tendency for material to adhere to the cutting edge, minimising built‑up edge and improving surface finish on each pass. For manufacturers focused on throughput, that translates into fewer interruptions for cleaning and a more predictable production flow.

Stable geometry for predictable results and tool life

The square 90° geometry provides four usable cutting edges per indexation and creates a robust cutting corner that withstands moderate interruptions and side forces. With an 11° relief angle and the specified insert dimensions (inscribed circle 12 mm, thickness 4 mm), the insert offers a balance between edge strength and low cutting forces. The K88 chipbreaker is tuned to break and evacuate chips efficiently in soft and ductile materials, which reduces machining chatter and helps maintain dimensional consistency.

Practical shop‑floor benefits and application clarity

As an indexable insert from the Walter N‑series, the component simplifies inventory and reduces downtime compared with brazed or solid tools: quick indexing gives four fresh edges without regrinding, while the uncoated design avoids coating‑related build‑ups in sticky alloys. The result is a cost‑effective solution for finishing and semi‑finishing operations on aluminium, copper and messing (brass). Where precise, burr‑free edges are required, the combination of grade and chipbreaker supports repeatable, high‑quality results.

FAQ

Which materials is this insert best suited for?
The SPGT1204AEN-K88 WXN15 is designed for non‑ferrous metals (ISO group N) such as aluminium, copper and brass, where a sharp, uncoated edge and controlled chip formation are beneficial.

Is the cutting material coated?
No — the WXN15 grade is an uncoated cemented carbide, chosen to keep the cutting edge sharp and to reduce adhesion when machining soft, sticky alloys.

What are the physical dimensions and geometry of the insert?
The insert has a square 90° form, inscribed circle of 12 mm, thickness of 4 mm, and an 11° relief angle, combined with the K88 chipbreaker for chip control.

Can the insert be indexed to use multiple cutting edges?
Yes — the square geometry provides four indexable cutting edges, allowing quick rotation to a fresh edge without regrinding.

Which Walter series does this insert belong to and what does that mean for selection?
This item is part of the Walter N‑series, which is optimised for sharp, uncoated performance in non‑ferrous alloys and simplifies grade selection for aluminium and similar materials.
