SDMT09T308-F57 WKP35S – Milling indexable insert (Tiger‑tec Silver) for Steel & Cast Iron by Walter Tools

The SDMT09T308-F57 WKP35S is a square 90° milling indexable insert engineered for high-productivity roughing and finishing of steel and cast iron, combining a coated carbide grade with a chipbreaker tuned for stable swarf formation

• Tiger·tec Silver coated carbide grade WKP35S
• 15° clearance angle for positive cutting geometry
• 0.8 mm corner radius for improved edge strength
• Optimised F57 chipbreaker for stable chip control

Consistent chip control for uninterrupted production

The insert’s F57 chipbreaker is designed to shape and evacuate chips reliably during milling, reducing the risk of re-cutting and tool interruption. In practice, a well-matched chipbreaker minimises built-up edge and prevents long, stringy swarf from tangling in the cutter, which improves cycle stability. Reliable chip control translates directly into fewer machine stops and more predictable batch throughput for shops prioritising uptime and process repeatability.

Coating and grade engineered for steel and cast iron

The Tiger‑tec Silver coating combined with the WKP35S grade gives a balanced solution for the ISO groups P and K, i.e. steel and cast iron. Coated carbide reduces flank and crater wear by improving thermal resistance and hardness at the cutting edge; for the end user this means longer intervals between index changes and a better total cost of ownership. Where abrasive cast iron or heat-prone steels are machined, the coated grade helps maintain a stable cutting edge under variable cutting conditions.

Geometry and edge design that boost edge life

A 15° clearance angle and a 0.8 mm corner radius create a robust cutting geometry that resists chipping while maintaining favourable cutting forces. The modest corner radius distributes cutting loads across a larger area of the edge, improving resistance to mechanical shock during interrupted cuts. For shoulder milling and face operations, the square 90° format delivers predictable plunge and step-over behaviour, allowing process engineers to set feeds and depths with confidence.

Integration into the toolchain and practical advantages

The insert is specified as SDMT09T308‑F57 in ISO format and uses a T3 plate thickness in size 09, making it compatible with standard indexable milling cutters designed for square inserts. Its execution and tolerance class M support consistent repeatability in production series. By pairing the insert with the correct cutter body and clamping torque, workshops gain a reliable, serviceable solution that supports both roughing and semi-finishing operations, reducing the need for frequent requalification of tool settings.

FAQ

What materials is this insert suitable for?
The SDMT09T308-F57 WKP35S is designed for ISO groups P and K, making it suitable for machining steel and cast iron in a range of production applications.

How does the F57 chipbreaker affect machining?
The F57 chipbreaker promotes short, controllable chips and reliable evacuation, which reduces the risk of chip-related interruptions and contributes to steady machining performance with the Walter Tools insert.

Is the insert suitable for finishing as well as roughing?
Yes; the combination of the 0.8 mm corner radius and Tiger‑tec Silver coating provides a compromise between edge strength and surface finish, allowing use in both heavy and semi-finishing operations when set up appropriately.

Which cutter bodies are compatible with this ISO designation?
The insert follows the ISO-style designation SDMT09T308‑F57 and fits standard milling cutters specified for square 90° inserts of size 09 and T3 thickness; selection of the correct body and clamping ensures repeatable performance.

How does the Tiger‑tec Silver coating influence tool life?
Tiger‑tec Silver enhances thermal and abrasive resistance at the cutting edge, typically extending edge life compared with uncoated grades and stabilising wear behaviour on both steel and cast iron.
