DCGT070202-FM2 WSM20S indexable turning insert – Tiger·tec Silver, 7° relief (Walter Tools)

The DCGT070202-FM2 WSM20S is an indexable turning insert designed for secure, productive machining of rostfreier Stahl and heat‑resistant superalloys, delivering controlled chip formation and consistent edge life.

• Tiger·tec Silver coating for high thermal resistance
• WSM20S coated carbide for rostfreier Stahl and superalloys
• Rhombic 55° form with 0.2 mm corner radius
• 7° relief and FM2 chipbreaker for stable chips

Increased productivity through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WSM20S grade provides a balance of heat resistance and edge strength that translates directly into more reliable cycle times when working with demanding materials. Coated carbide improves thermal stability at the cutting zone and reduces the risk of adhesive wear; as a result, tool life becomes more predictable and downtime is reduced. This technical pairing is particularly suitable for components where consistent performance on rostfreier Stahl or titanium‑containing alloys matters to throughput.

Predictable chip control and better surface integrity

The integrated FM2 chipbreaker together with the rhombic 55° geometry and a 0.2 mm corner radius promotes controlled chip formation and evacuation. For operations prone to built‑up edge or poor chip evacuation—typical with rostfreier Stahl and nickel‑based superalloys—this geometry supports stable cutting forces and improves surface finish. The moderate corner radius helps to distribute cutting stresses without compromising dimensional accuracy, making the insert well suited for medium to finishing passes where surface quality is a priority.

Robust geometry for versatile turning operations

A relief angle of 7° creates a favourable clearance for many turning setups while maintaining cutting edge support. The insert’s designation and form ensure compatibility with standard rhombic toolholders and allow straightforward indexation to a fresh cutting edge. As the grade is a coated carbide, the insert combines toughness with wear resistance, which reduces the frequency of tool changeovers and simplifies inventory management for production environments that process a mix of rostfreier Stahl and difficult‑to‑cut alloys.

Practical application guidance and pairing recommendations

For best results, pair the insert with a rigid toolholder and a stable clamping setup to exploit the grade’s edge stability. When machining rostfreier Stahl or heat‑resistant alloys, moderate cutting speeds and higher feed rates often improve chip breaking and heat distribution; the WSM20S grade is developed to support such strategies. Where possible, match coolant and machining parameters to the workpiece to avoid thermal shock; the insert’s coating and chipbreaker will assist in maintaining consistent performance across sequential parts.
