CNMU160812-D57T WPP35G — Indexable milling insert for steel, Tiger·tec Gold (Walter Tools)

The CNMU160812-D57G WPP35G is an indexable milling insert designed for steel machining, combining a rhombic 80° geometry with a D57T chipbreaker and Tiger·tec Gold coated carbide for productive cutting performance

• Tiger·tec Gold coated carbide
• For machining steel (ISO P)
• Rhombic 80° shape, 1.2 mm corner radius
• Negative rake 0° with D57T chipbreaker

Efficient, repeatable milling for steel production

The Tiger·tec Gold coating paired with the WPP35G grade provides a balance between wear resistance and toughness that suits a broad range of steel applications (ISO P). The coated carbide substrate reduces flank wear and improves resistance to thermal loading during interrupted cuts, which translates into longer tool life and fewer index changes. The D57T chipbreaker is engineered to produce stable chips when machining steels, reducing the risk of re-cutting and minimising downtime for chip management. This section focuses on measurable efficiency gains and process stability rather than abstract promises.

Geometry and cutting behaviour that support precision and surface quality

The rhombic 80° shape combined with a 1.2 mm corner radius and a 0° negative relief angle promotes secure positioning in the milling cutter and reliable edge strength for shoulder and face milling tasks. The geometry delivers controlled cutting forces and helps maintain consistent dimensional accuracy across batches. For applications where edge strength and surface finish matter, the insert’s form factor supports both roughing and semi-finishing passes while preserving component integrity.

Practical advantages for shop-floor integration

From a production standpoint, the insert’s tolerance class M and standard ISO designation allow straightforward tool planning and inventory management. The insert is suitable for general steel machining and offers predictable behaviour across different feed and speed windows when paired with appropriate cutter bodies. Reduced tool change frequency and consistent machining results contribute to measurable cost savings per component and a more efficient production flow.

Application advice and process considerations

When processing medium to high-strength steels, select cutting parameters that leverage the coating’s thermal stability: moderate cutting speeds, stable feeds and appropriate coolant application where needed. The D57T chipbreaker performs best when chip thickness is kept within recommended ranges for the material group; this results in compact chips and improved evacuations in pockets and slots. For unconventional alloys or highly interrupted cuts, consult the technical spec sheet or Metav Werkzeuge’s advisors to verify parameter windows and optimisation strategies.

FAQ

What materials is this insert suited for?
The CNMU160812-D57T WPP35G insert is designed for steel machining (ISO P); the WPP35G grade and Tiger·tec Gold coating optimise performance for typical steel cutting conditions.

How does the D57T chipbreaker affect machining?
The D57T chipbreaker on the CNMU160812-D57G WPP35G helps form compact chips during steel machining, improving chip evacuation and reducing the risk of recutting.

What benefits does the Tiger·tec Gold series deliver?
Tiger·tec Gold coating on the WPP35G grade increases wear resistance and thermal stability, which supports longer tool life and consistent cutting performance in steel applications.

Is the 1.2 mm corner radius suitable for finishing?
A 1.2 mm corner radius provides a good compromise between edge strength and surface finish; for fine finishing passes consider the cutter configuration and feed rates to achieve the required surface quality.

What does the negative 0° relief angle mean for setup?
The negative 0° relief angle indicates a robust cutting edge and secure seating in the cutter body, which can enhance stability for heavier cuts and interrupted milling operations.
