CPGT09T301-MM4 WSM01 — Walter Tools indexable insert, Tiger‑tec Silver, 11° clearance, 0.1 mm nose radius

The CPGT09T301-MM4 WSM01 is an indexable insert designed for boring and turning operations on stainless steels and heat‑resistant superalloys, offering a balance between edge stability and surface quality.

• Tiger‑tec Silver coating for heat resistance
• Grade WSM01 for stainless and superalloys
• 11° clearance angle for stable engagement
• 0.1 mm nose radius for precise finishing

Improved reliability on stainless steels and superalloys

The combination of the Tiger‑tec Silver series and the WSM01 grade gives a coated carbide performance tailored to materials that challenge cutting edges. The platelet's substrate and coating chemistry favour thermal resilience and oxidation resistance, which helps to reduce built‑up edge and maintain a stable cutting edge under elevated temperatures. For ISO group M (stainless steels) and S (superalloys, titanium), this results in more predictable tool life and consistent component surface integrity, especially where heat generation and material work hardening would otherwise compromise process stability.

Geometry engineered for chip control and surface finish

The insert’s rhombic 80° form, combined with an 11° clearance angle and a 0.1 mm nose radius, creates a cutting geometry that supports both robust engagement and fine finishing. The MM4 chipbreaker is configured to promote segmented, controllable chips in difficult‑to‑machine materials, reducing the risk of long stringing chips and improving evacuation. With a T3 insert thickness, the design offers sufficient rigidity for interrupted cuts while allowing precise edge contact for finishing passes, resulting in reduced rework and improved first‑pass yields.

Productivity gains through stable cutting and predictable life

In series production, repeatability and minimal process variation are decisive. The CPGT09T301‑MM4 in WSM01 provides a combination of wear resistance and edge stability that reduces index‑and‑replace frequency and supports longer uninterrupted runs. Stable chip formation and a consistent edge condition decrease the likelihood of unexpected tool changes and enable tighter control of surface roughness, which translates into lower machining costs per part and higher overall equipment effectiveness. For integration into toolrooms, the insert’s standard designation and form factor simplify holder selection and inventory management.

FAQ

Which materials is this insert suited for?
The CPGT09T301‑MM4 WSM01 is intended for stainless steels and heat‑resistant superalloys (ISO groups M and S); the WSM01 grade and Tiger‑tec Silver coating enhance thermal resistance and chip behaviour on these materials.

What machining tasks match this geometry?
The rhombic 80° form and 0.1 mm nose radius are suitable for a mix of roughing and finishing in turning and boring applications, where a balance of edge strength and surface quality is required.

How does chip control perform with this insert?
The MM4 chipbreaker is designed to produce stable, segmented chips in demanding materials, improving evacuation and reducing the risk of chip interference during continuous machining.

What impact does the WSM01 grade have on tool life?
WSM01 is a coated carbide grade engineered for materials that generate heat and strain the cutting edge; it provides improved edge life and a more consistent wear pattern, helping to extend operating intervals between indexing.

Is the insert compatible with standard holders for CPGT inserts?
The CPGT09T301‑MM4 format follows common CPGT indexable insert dimensions; compatibility should be checked against holder specifications to confirm seat and clamp fit.
