SEHW1204AFN WAK15 milling indexable insert — square 90°, 20° clearance — Walter Tools

The SEHW1204AFN WAK15 is a square milling indexable insert optimised for high‑performance machining of aluminium and other non‑ferrous metals, designed for use in Walter’s N‑system.

• WAK15 uncoated carbide for N materials
• Walter N‑system compatibility
• 20° clearance angle for low friction
• Square 90° form for versatile milling

High productivity for aluminium and non‑ferrous metals

The combination of the WAK15 grade and an uncoated carbide substrate targets efficient machining of aluminium and similar alloys (ISO group N). The material and geometry focus on minimising built‑up edge and reducing adhesion, which keeps the cutting edge sharper for longer and improves surface finish on difficult, gummy materials. As a result, cycle times can be shortened and rework reduced, delivering a clear economic advantage in serial production and jobbing environments where consistent part quality matters.

Geometry that improves cutting action and tool life

A 20° clearance (freedom) angle and the square 90° insert form offer a robust cutting edge with predictable strength and multiple indexed edges. The relief geometry reduces rubbing on the workpiece, lowering heat generation and friction during light to medium cuts. The designation thickness 04 and nominal size 12 denote the insert’s compact profile, making it suitable where a balance of stiffness and access is required. When fitted in a compatible holder, this geometry supports repeatable results and cost‑efficient edge utilisation.

System compatibility and process reliability

Designed for the Walter N‑system, the insert integrates into tool assemblies that prioritise repeatability and rapid index changes. The sharp cutting edge geometry indicated in the series data reduces material adhesion and optimises chip formation for non‑ferrous alloys, which simplifies process planning. As an indexable insert, the SEHW1204AFN WAK15 enables quick edge changes without complex regrinding, supporting lean production workflows and lowered tooling overheads. For operations seeking stable, predictable performance when machining aluminium components, this insert represents a practical choice.

FAQ

What materials is this insert intended for?
The SEHW1204AFN WAK15 is intended primarily for aluminium and other non‑ferrous metals (ISO group N); the WAK15 grade and edge geometry reduce adhesion and improve surface quality on these materials.

Is the insert coated?
This insert is uncoated carbide (WAK15), selected to provide a very sharp cutting edge and low tendency for material to stick during non‑ferrous machining.

Which clearance angle does the insert have?
The insert features a 20° clearance angle, which reduces rubbing and helps maintain edge stability during milling of softer metals.

How many cutting edges are available per insert?
With a square 90° form, multiple usable edges are provided by indexing the insert, offering economical edge utilisation for repetitive milling tasks.

Is the insert compatible with standard Walter toolholders?
The SEHW1204AFN WAK15 is designed for the Walter N‑system and is compatible with holders specified for that series; verify holder details to ensure correct mounting and clamping.
