TCGT16T308-MM4 WSM20S indexable insert — triangular 60°, Tiger·tec Silver coating — Walter Tools

The TCGT16T308-MM4 WSM20S is a triangular indexable insert designed for reliable machining of stainless steels and heat‑resistant superalloys, offering a compact 60° cutting geometry for versatile turning and drilling-related operations.

• Tiger·tec Silver coating for heat resistance
• WSM20S grade for stainless and superalloys
• 60° triangular insert with 0.8 mm radius
• 7° relief angle for stable cutting edge

Consistent performance for difficult-to-machine materials

The coated‑carbide WSM20S grade, part of the Tiger·tec Silver series, is formulated to deliver stable chip formation and extended edge life when working with stainless steels (ISO group M) and heat‑resistant alloys or titanium (ISO group S). The 60° triangular shape combined with a 0.8 mm corner radius provides a balance between strength and accessibility; larger radii increase cutting edge robustness, while the triangular form allows three indexable corners per insert. These features reduce tool change frequency and enhance process reliability in continuous production environments.

Clear advantages in machining strategy and chip control

The insert’s MM4 chipbreaker is engineered to manage chips effectively under varying cut depths and feed rates, reducing the risk of built‑up edge and improving surface finish. For less experienced users: a chipbreaker shapes and breaks the chips produced during cutting, directing them away from the workpiece and toolholder to avoid interference. The 7° relief angle lowers friction behind the cutting edge and helps maintain stable cutting forces, which translates into predictable tool behaviour and consistent cycle times on the shopfloor.

Compatibility, handling and application guidance

With a nominal size of 16 mm and thickness T3, the insert fits industry‑standard toolholders configured for triangular TCGT inserts; the tolerance class G ensures repeatable seating accuracy. Selection of the WSM20S grade is particularly worthwhile where thermal resistance and edge stability are priorities—typically in semi‑finishing and finishing passes on corrosion‑resistant steels and nickel‑based alloys. For procurement and inventory planning, the insert’s geometry and grade allow flexible deployment across toolsets, supporting both productivity improvements and stock rationalisation.

FAQ

Which materials is this insert suitable for?
The TCGT16T308-MM4 WSM20S is suited for stainless steels and heat‑resistant superalloys (ISO groups M and S) thanks to the WSM20S coated‑carbide grade and Tiger·tec Silver technology.

Is the insert compatible with standard triangular insert holders?
Yes, the insert’s 60° triangular form and 16 mm size are compatible with standard toolholders designed for TCGT‑type inserts; verify holder designation matches the insert geometry.

What is the function of the MM4 chipbreaker?
The MM4 chipbreaker assists chip formation and breaking to prevent long, stringy chips, improving surface finish and reducing the risk of chip interference during turning or drilling‑related operations.

How does Tiger·tec Silver benefit machining?
Tiger·tec Silver coating increases heat resistance and edge stability, which helps maintain cutting performance and prolongs tool life when machining materials that generate high cutting temperatures.

When is a 0.8 mm corner radius recommended?
A 0.8 mm corner radius offers a compromise between edge strength and cutting accessibility; it is recommended for general finishing and medium engagement where enhanced edge life is required.
