SDMT09T3AZN-F57 WKP25S milling insert – Tiger·tec Silver, 15° clearance (Walter Tools)

The SDMT09T3AZN-F57 WKP25S is a square 90° milling insert engineered for productive machining of steel and cast iron with a Tiger·tec Silver coated, T3-thickness construction.

• Tiger·tec Silver coating for high wear resistance
• WKP25S grade optimised for steel and cast iron
• Square 90° geometry with 15° clearance
• T3 thickness for stable cutting edge and repeatability

Consistent chip control for more productive milling

The square 90° geometry combined with the F57 chipbreaker provides reliable chip formation during interrupted and continuous cuts, which reduces secondary operations and machine downtime. Designed for common steel and cast-iron tasks, the insert’s geometry promotes predictable chip flow and lowers the risk of built-up edge. The result is improved process stability and fewer rejected parts when machining components where repeatable dimensions matter.

Longer edge life thanks to advanced coating and grade

The Tiger·tec Silver coating together with the WKP25S coated carbide grade reduces abrasive wear and resists thermal stress during typical steel and cast-iron applications. This coating technology is developed to preserve the cutting edge at elevated cutting speeds, extending tool life and cutting intervals. For production environments where tool change frequency affects cycle time, this combination is an economical choice that supports consistent surface finish and dimensional accuracy.

Robust mechanical design for secure clamping and repeatability

With a T3 thickness and M tolerance class, the insert offers mechanical stability and repeatable seating in standard milling toolholders. The square format with a 90° cutting corner enables straightforward indexation and multiple effective cutting edges per insert, improving usage efficiency. The 15° clearance angle reduces friction at the flank, lowering cutting temperatures and enabling stable performance in a wide range of feeds and depths of cut.

Application focus and where the insert adds most value

This insert is intended primarily for machining operations involving unalloyed and alloyed steels as well as cast irons, reflecting the P/K applicability classification. It suits face and shoulder milling tasks where robust edge retention and reliable chip breaking are required. For engineers seeking a balance between tool life and productivity, the SDMT09T3AZN-F57 WKP25S insert supports higher process reliability and predictable component quality in medium-to-high volume production settings.

FAQ

What materials are suitable for this insert?
The SDMT09T3AZN-F57 WKP25S insert is specified for P (steel) and K (cast iron) applications and is optimised for machining unalloyed/alloyed steels and cast-iron components.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating on the WKP25S grade reduces abrasive wear and improves thermal resistance, extending edge life and maintaining surface quality in typical milling operations.

What does the 15° clearance provide in practice?
A 15° clearance angle reduces flank contact and friction, which helps to lower cutting temperatures and supports stable tool performance across varying feeds and depths of cut.

Is the insert suitable for interrupted cuts and heavy milling?
Yes, the square 90° geometry and F57 chipbreaker are designed to provide controlled chip formation and stable cutting in many interrupted and continuous milling scenarios.

How many cutting edges are available per insert and how is repeatability ensured?
The square format provides multiple indexable cutting edges; the T3 thickness and M tolerance class ensure secure seating and repeatable positioning in compatible milling holders.
