SDMW09T320-A57 WKP35G — Milling indexable insert, Tiger·tec Gold, for steel & cast iron (Walter Tools)

SDMW09T320-A57 WKP35G is a square 90° milling indexable insert with a 15° clearance angle, designed for efficient chip formation and stable cutting in steel and cast iron applications

• Tiger·tec Gold coating for extended tool life
• Square 90° insert with 2 mm corner radius
• 15° clearance angle for stable cutting
• Designed for steel and cast iron machining

Consistent chip control for reliable cycle times

The combination of the A57 chipbreaker and the WKP35G coated-carbide grade delivers controlled chip formation under typical cutting temperatures for steel and the abrasive nature of cast iron. The chipbreaker geometry reduces chatter and helps maintain a uniform material flow during cutting, which leads to repeatable cycle times and fewer interruptions for swarf management. This rational optimisation supports higher throughput and predictable process planning in series production.

Precise geometry for reproducible surface quality

A defined 15° clearance angle and a 2 mm corner radius on the square 90° insert give a stable cutting edge and low tendency to edge chipping. The geometry and tolerance class M ensure consistent seating and alignment in standard toolholders, so that each index change returns the insert to the same datum. For workshops aiming at consistent component tolerances, these features translate into reduced set-up time and less rework due to dimensional drift.

Optimised for steel and cast iron according to ISO groups

The grade is specified for ISO groups P (steel) and K (cast iron). This means the substrate and coating are balanced to handle the heat and ductile chip formation of steels, while simultaneously resisting the abrasive wear seen in many cast-iron cuts. For users with mixed batches of turned and milled parts, the insert provides versatile performance across the two most common engineering materials without frequent grade changes.

Durable coating and economical tool life

The Tiger·tec Gold coating technology applied to the WKP35G grade improves resistance to flank and crater wear, extending the useful life of the insert under medium to high cutting speeds. Longer edge life reduces tooling change frequency and contributes to lower cost per part in continuous production. The combination of coating and chipbreaker supports both roughing and semi-finishing operations where consistent edge integrity and process stability are priorities.

FAQ

Which materials is this insert suitable for?
The SDMW09T320-A57 WKP35G insert is specified for ISO groups P and K, meaning it is suitable for machining steel and cast iron as supplied by Walter Tools.

What does the 2 mm corner radius affect in practice?
A 2 mm corner radius increases edge strength and distributes cutting forces, improving resistance to chipping and helping to achieve stable surface finishes during milling with the SDMW09T320-A57 WKP35G insert.

How does the Tiger·tec Gold coating benefit performance?
The Tiger·tec Gold coating reduces abrasive and thermal wear on the cutting edge, extending tool life and maintaining cutting-edge integrity under higher speeds, which benefits productivity with the WKP35G grade.

What is the role of the A57 chipbreaker?
The A57 chipbreaker promotes reliable chip formation and evacuation, reducing the risk of tangling and helping to maintain consistent machining conditions when using the SDMW09T320-A57 WKP35G insert.
