SDMT09T308-F57 WAK15 milling insert (square 90°, 0.8 mm) – Walter Tools

The SDMT09T308-F57 WAK15 is a square milling indexable insert engineered for high-performance machining of aluminium and other non‑ferrous metals, offering sharp cutting geometry and optimised chip evacuation.

• Uncoated carbide grade WAK15 for aluminium
• Square 90° insert form
• 0.8 mm corner radius
• 15° clearance angle
• Tolerance class M for consistent fit

Faster, cleaner results for aluminium and non‑ferrous work

The combination of the WAK15 grade and the chipbreaker F57 delivers a machining solution tailored to aluminium and similar non‑ferrous materials. The uncoated carbide substrate provides a very sharp cutting edge that reduces material adhesion and minimises built‑up edge, while the chipbreaker geometry encourages short, controlled chips. The direct benefit is improved surface quality and fewer interruptions for manual cleaning, which raises throughput and reduces non‑productive time. For shops aiming to increase part quality in series production, this geometry balances cutting performance with reliable tool life.

Consistent assembly and repeatable machining accuracy

With tolerance class M and a square 90° form, the insert ensures predictable positioning in compatible tool holders. The 15° clearance angle supports a stable cutting geometry that reduces rubbing on the flank and lowers cutting forces during engagement. The nominal size designation (09) and thickness T3 give a compact, stiff insert body suitable for medium‑feed milling operations. These features translate into reproducible results across batches and simplify tool change procedures, helping to maintain tight tolerances in repetitive production environments.

Reliable chip control and surface finish with low rework risk

A 0.8 mm corner radius provides a practical balance between edge strength and finish capability: it improves resistance to edge chipping while still enabling a fine surface on finishing passes. The F57 chipbreaker is configured to break and eject chips effectively when cutting non‑ferrous materials, reducing the chance of recutting or surface marks. The insert’s uncluttered geometry makes it well suited to high feed rates where consistent chip behaviour is essential, supporting higher material removal rates with fewer quality deviations and less manual rework.

FAQ

Which materials are best suited to this insert?
The SDMT09T308-F57 WAK15 insert is optimised for aluminium and other non‑ferrous metals; the WAK15 grade and F57 geometry reduce material adhesion and ensure controlled chips.

Is the cutting grade coated?
The WAK15 grade used in the SDMT09T308-F57 is an uncoated carbide formulation designed to maintain a very sharp edge for non‑ferrous machining.

What does the 0.8 mm corner radius affect in practice?
A 0.8 mm corner radius on the SDMT09T308-F57 increases edge strength and improves surface finish on light to medium finishing passes while maintaining acceptable cutting forces.

How does the chipbreaker F57 influence machining?
The F57 chipbreaker promotes short, controllable chips when cutting aluminium and similar materials, reducing the risk of chip entanglement and improving process consistency with the SDMT09T308-F57 WAK15.
