SDMT1204AZN-D57 WKP35G milling insert — 15° clearance, square 90° — Walter Tools

SDMT1204AZN-D57 WKP35G is a coated indexable insert engineered for robust face and shoulder milling in steel and cast iron applications

• Tiger‑tec Gold coated for long tool life
• Grade WKP35G for steel and cast iron
• 15° clearance, square 90° geometry
• D57 chipbreaker for controlled chips

Higher productivity through a wear‑resistant coating

The Tiger‑tec Gold coating paired with the WKP35G carbide grade provides a measurable improvement in tool life and process reliability when machining ISO group P (steel) and ISO group K (cast iron). This combination reduces flank and crater wear under elevated cutting temperatures, which in turn extends effective tool life and lowers overall tool cost per component. The coating technology also supports higher cutting speeds where appropriate, enabling greater material removal rates and shorter cycle times while maintaining dimensional stability.

Predictable chip control and improved surface finish

The chipbreaker D57 is designed to produce short, consistent chips when paired with the square 90° geometry and 15° clearance, improving evacuation and reducing the risk of re-cutting. Controlled chip formation leads to a more repeatable surface quality and decreases the likelihood of tool-induced workpiece damage. In practice, this results in fewer interruptions for chip clearing and reduced secondary finishing work, supporting continuous machining with fewer process deviations.

Reduced set‑up time and straightforward indexability

Made in the standard SDMT family format with a 12 mm size and thickness 04, the insert uses a common ISO envelope that simplifies stocking and replacement across compatible milling cutters. The square form permits four cutting edges per indexable insert, which maximises usable tool life and reduces downtime for tool changes. The indexable insert design facilitates predictable seating and repeatable positioning in the cutter body, making it suitable for production environments that demand rapid tool changeovers and consistent component quality.

Broad material coverage with industrial robustness

Certified for machining steel and cast iron according to ISO group designations, the grade provides versatility for mixed production batches or job shops handling varied alloys. The insert’s tolerance class M and execution T ensure stable clamping and geometric repeatability in precision setups. As a Walter Tools product from the Tiger‑tec Gold series, it combines industrially proven substrate and coating technology for reliable performance in medium to heavy milling operations where process security and surface integrity are essential.

FAQ

What materials is this insert suitable for?
This insert is specified for ISO groups P and K, meaning it is suitable for machining steel and cast iron; the WKP35G grade and Tiger‑tec Gold coating are tuned to those material behaviours.

How does the D57 chipbreaker affect machining?
The chipbreaker D57 produces short, consistent chips and improves evacuation in interrupted or continuous milling, helping to maintain surface quality and reduce rework when using this indexable insert.

Can the insert be indexed to use all cutting edges?
Yes; the square 90° format allows multiple indexing positions. The SDMT family format and tolerance class M ensure repeatable seating and stable clamping for effective edge utilisation.

Is this insert compatible with high‑speed milling?
The Tiger‑tec Gold coating enhances thermal resistance and wear control, enabling elevated cutting speeds for many steel and cast iron operations when combined with appropriate feeds and machine capability.
