SDMT120420-F57 WKP35S Tiger·tec Silver indexable milling insert by Walter Tools — F57 chipbreaker, 15° relief angle

The SDMT120420-F57 WKP35S is a Tiger·tec Silver indexable milling insert engineered for productive machining of steel and cast iron in general milling applications.

• Tiger·tec Silver coating, WKP35S grade
• Square 90° insert with 2 mm corner radius
• F57 chipbreaker for controlled chip formation
• For steel (P) and cast iron (K) machining

Improved machining performance through modern coating technology

The combination of the Tiger·tec Silver coating and the WKP35S substrate delivers a balance between wear resistance and edge stability that raises process reliability. The advanced coating reduces abrasive and adhesive wear during interrupted cuts and high thermal loads, which means longer intervals between index changes and fewer unplanned tool interventions. As a result, machining centres experience more consistent cycle times and improved overall productivity when processing steel and cast iron according to ISO 513 classifications.

Geometry engineered for strength and surface quality

The square 90° geometry with a 2 mm corner radius and a 15° relief angle provides a robust cutting edge suited to both roughing and semi-finishing operations. The substantial corner radius increases edge strength under heavier depths of cut, while the moderate relief angle supports effective chip evacuation and stable cutting forces. The integrated F57 chipbreaker further refines chip formation, promoting short, broken chips that reduce the risk of entanglement and improve surface finish on the workpiece. These features together lower tool change frequency and support predictable component quality.

Versatile application scope and process guidance

Classified for material groups P (steel) and K (cast iron), the insert is suitable for a wide range of industrial milling tasks where balanced wear resistance and reliable chip control are required. The medium tolerance class M and the insert’s layout make it appropriate for shops seeking repeatable performance across mixed batches of unalloyed, alloyed steels and various cast irons. Selection of the SDMT120420-F57 WKP35S is recommended where a compromise between edge life and finish quality is desired, and where the machining strategy benefits from the insert’s predictable behaviour under standard cutting conditions.

FAQ

What materials are best suited to this insert?
The SDMT120420-F57 WKP35S insert is designed primarily for steel (P) and cast iron (K) applications, using the Tiger·tec Silver coating to manage heat and abrasive wear.

How does the F57 chipbreaker influence machining?
The F57 chipbreaker on this Walter Tools insert promotes controlled, broken chips, improving chip flow and reducing the likelihood of chip-related interruptions during milling.

Which geometries and operations benefit most from the 2 mm corner radius?
A 2 mm corner radius increases edge robustness for heavier engagement and is particularly beneficial in roughing and semi-finishing where edge strength and load distribution are critical.

Is this insert suitable for finishing work?
The SDMT120420-F57 WKP35S offers a compromise between wear resistance and surface quality; fine finishing is possible with appropriately tuned cutting parameters and machine rigidity.

What does the tolerance class M indicate for shop planning?
Tolerance class M denotes medium tolerances appropriate for many general machining tasks, balancing interchangeability with reasonable manufacturing cost.
