SDGT1204AZN-F57 WAK15 milling insert — uncoated carbide, 15° clearance | Walter Tools

A SDGT1204AZN-F57 WAK15 milling insert designed for efficient machining of aluminium and other non‑ferrous metals, combining a square 90° geometry with the F57 chipbreaker for controlled chips and consistent surface quality.

• Uncoated carbide for sharp edges
• 15° clearance for low friction
• Square 90° geometry for stability
• F57 chipbreaker optimised for aluminium

Consistent productivity through controlled chip formation

The combination of uncoated carbide (WAK15) and the F57 chipbreaker delivers predictable, short chips when machining aluminium and other non‑ferrous materials. This results in reduced machining interruptions and fewer tool changes, supporting a higher throughput. The insert’s geometry promotes stable cutting conditions, which helps maintain cycle times and reduces the need for secondary operations, translating into measurable productivity gains on the shop floor.

Geometry engineered for low cutting forces and surface quality

A square 90° form together with a 15° clearance reduces rubbing and minimises heat build‑up at the cutting edge. The moderate clearance angle lowers cutting forces, improving tool life and helping to avoid built‑up edge formation common with soft materials. The plate’s dimensions (size 12, thickness 04) and tolerance class G ensure repeatable fitment in standard Walter seating, enabling consistent part quality and easier tool changeovers in production environments using the Walter N‑Sortensystem.

Application focus: aluminium and non‑ferrous metals

This grade is specified for N‑group materials; the insert’s sharp edge geometry and uncoated carbide suit aluminium and non‑ferrous alloys where adhesion and material smear can be an issue. The result is improved surface finish and reduced secondary machining. The insert is particularly suitable for manufacturers and subcontractors who require reliable performance in series production and repeatable results across batch runs.

Practical benefits and system compatibility

Designed for use within the Walter N‑Sortensystem, the insert offers straightforward integration into existing toolholders, simplifying inventory and setup management. The execution and chip control make it well suited to both roughing and semi‑finishing passes in non‑ferrous applications, while the robust carbide grade promotes consistent edge retention. For teams seeking a balance of cutting quality and operational efficiency, this insert helps lower rework rates and supports predictable cycle times.

FAQ

What materials is this insert intended for?
The SDGT1204AZN-F57 WAK15 is intended for aluminium and other non‑ferrous metals, corresponding to ISO material group N; its sharp edge geometry and chipbreaker minimise adhesion and improve surface finish.

How does the 15° clearance influence machining?
A 15° clearance reduces rubbing and cutting forces, which helps avoid built‑up edge and lowers heat generation when machining soft, adhesive materials like aluminium.

Is the insert compatible with standard Walter holders?
Yes, the insert follows the Walter N‑Sortensystem seating and the SDGT format, ensuring compatibility with matching Walter toolholders and straightforward replacement logistics.

What is the chip control behaviour of the F57 breaker?
The F57 chipbreaker is optimised to produce controlled, manageable chips in non‑ferrous machining, reducing entanglement and aiding uninterrupted production cycles.

Can the grade WAK15 be used for finishing passes?
The uncoated WAK15 grade is suitable for both roughing and semi‑finishing in aluminium; its sharp cutting edge can achieve good surface quality depending on cutting parameters and machine rigidity.
