SDMT06T204-F57 WAK15 — milling indexable insert, 15° relief (Walter Tools)

SDMT06T204-F57 WAK15 is a square 90° milling insert engineered for aluminium and other non‑ferrous metals, combining a 15° clearance angle with a fine 0.4 mm corner radius for accurate, burr‑reduced machining

• Square 90° insert geometry
• Uncoated carbide grade WAK15
• Optimised for aluminium and non‑ferrous metals
• Chipbreaker F57 for controlled chips

Precision and material compatibility for non‑ferrous work

The insert is based on the WAK15 uncoated carbide grade within the Walter N‑series, developed specifically for aluminium and other non‑ferrous materials (ISO 513 group N). The combination of a sharp cutting edge and a smooth rake geometry reduces material adhesion and burr formation, which translates into fewer secondary operations and improved cycle times. For shops transitioning from brazed tools to indexable systems, the insert offers predictable edge behaviour and easier tool management.

Controlled chip formation and improved surface quality

Equipped with chipbreaker F57 and a small 0.4 mm corner radius, this square insert produces short, manageable chips and helps maintain a consistent cutting edge engagement. The 15° relief reduces rubbing on non‑ferrous alloys and supports higher feed rates without compromising surface finish. For those less familiar with insert geometry: the chipbreaker shapes the way material breaks off during cutting, and the corner radius influences both strength and finish — a fine radius favours a cleaner edge on soft metals.

Robust process performance and economical machining

As an uncoated carbide solution, this insert prioritises sharpness and low built‑up edge for soft alloys; it avoids coatings that might increase friction in certain non‑ferrous applications. The square 90° form provides four usable cutting edges per indexable plate, increasing tool utilisation and reducing tooling costs per part. The tolerance class M and Walter’s series design ensure repeatable seating and consistent runout behaviour in standard clamp systems, supporting steady production runs.

Integration into workshop operations

The insert’s designation and form factor make it straightforward to index and replace within common milling cutters that accept SDMT‑style plates. The modest geometry demands standard machine power and cooling strategies; many workshops will notice immediate improvements in finish and reduced rework when switching to a carbide insert tailored for non‑ferrous metals. Technical teams benefit from predictable tool life and straightforward stock keeping thanks to the clear series and grade labelling.

FAQ

What materials is this insert intended for?
The SDMT06T204‑F57 WAK15 insert is optimised for aluminium and other non‑ferrous metals (ISO 513 group N) and performs best where sharp edges and low adhesion are required.

Does the insert come with a coating?
No; the WAK15 grade is an uncoated carbide designed for high sharpness and reduced built‑up edge in soft alloys.

How does the chipbreaker affect machining?
The F57 chipbreaker controls chip shape and evacuation, improving process stability and reducing the risk of chip entanglement during milling with the Walter Tools insert.

How many cutting edges are usable per plate?
The square 90° geometry provides four indexable edges per plate, offering efficient utilisation and economical tool management.

Which series and tolerance class apply to this insert?
It belongs to the Walter N‑Sortensystem and is manufactured to tolerance class M for consistent seating and repeatable performance.
