SCGT09T304-MM4 WSM01 — Square 90° Indexable Insert, Tiger‑tec Silver by Walter Tools

The SCGT09T304-MM4 WSM01 is a square 90° indexable insert optimised for heavy-duty machining of rostfreiem Stahl and heat‑resistant superalloys in turning and drilling-adjacent operations

• Tiger‑tec Silver for thermal stability and wear resistance
• Optimised MM4 chipbreaker for controlled chips
• 0.4 mm corner radius for repeatable edge life

Increased process reliability through coated‑carbide performance

The Tiger‑tec Silver coating and the WSM01 grade combine to deliver consistent tool life and lower risk of built-up edge during continuous production runs. The coated carbide substrate provides improved resistance to thermal degradation; together with the MM4 chipbreaker, it promotes predictable chip formation and evacuation. This results in fewer interruptions for tool changes and reduced scrap rates, supporting higher machine utilisation and dependable component quality.

Purpose-built for rostfreiem Stahl and demanding superalloys

The grade is specified for ISO groups M and S — that is, rostfreiem Stahl and heat‑resistant superalloys or titanium alloys. These materials generate elevated temperatures and tend to produce tough, stringy chips; the insert’s coating and geometry are engineered to maintain a stable cutting edge under those conditions. For shops transitioning from conventional grades, the insert helps reduce risks associated with work‑hardening and thermal loading, making it suitable where process security and repeatable surface finish matter.

Geometry and tolerances for consistent machining results

The Square 90° form, 7° relief angle and 0.4 mm corner radius combine to offer a balanced profile between robustness and versatility. The T3 thickness and tolerance class G ensure repeatable seating in toolholders and consistent cutting engagement across indexings. Such geometric stability simplifies tooling management: fewer adjustments are required, insert indexing is reliable and finished part tolerances remain constant over long production cycles, which supports efficient downstream processes.

FAQ

What materials is this insert best suited for?
The SCGT09T304-MM4 WSM01 from Walter Tools is intended for ISO groups M and S, making it suitable for rostfreiem Stahl and heat‑resistant superalloys, where thermal stability and chip control are critical.

How does the MM4 chipbreaker affect performance?
The MM4 chipbreaker on the SCGT09T304-MM4 WSM01 promotes controlled chip formation and evacuation, reducing the likelihood of entangling chips and improving surface finish consistency during long production runs.

What does the tolerance class G mean for tool setup?
Tolerance class G indicates tight manufacturing tolerances for the insert, ensuring consistent seating and repeatable geometry when indexing, which simplifies setup and reduces positional variation in the machining process.

Can this insert be used for finishing as well as roughing?
Depending on the chosen cutting parameters and holder setup, the insert’s geometry and 0.4 mm corner radius allow a balance between robust roughing and acceptable finishing results; parameter optimisation is recommended.

Is a special holder required for the Square 90° form?
The square 90° form uses standard indexable insert holders compatible with SCGT‑style seats; ensure the holder matches the insert thickness T3 and tolerance G for secure clamping.
