WCGT030204-FM2 WSM21 indexable insert — Trigon 80° geometry, FM2 chipbreaker (Walter Tools)

The WCGT030204-FM2 WSM21 is an indexable insert for drilling, boring and turning applications, engineered for machining rostfreier Stahl and heat-resistant superalloys in production and repair environments

• Coated cemented carbide WSM21 grade
• Trigon 80° insert geometry
• FM2 chipbreaker for stable chip control
• Suited for rostfreier Stahl and superalloys

Optimised grade for difficult-to-machine materials and consistent productivity

The WSM21 grade is a coated cemented carbide developed for materials that challenge conventional tooling. Its substrate and coating combination enhance heat resistance and edge life when facing the higher work hardening and thermal loads typical of rostfreier Stahl and superalloys. For production lines that require fewer tool changes and predictable tool life, this insert supports consistent cutting performance and reduced downtime. The specification of a coated carbide grade means improved wear resistance and a higher tolerance to thermal shock compared with uncoated substrates.

Geometry and edge preparation that control cutting forces and surface results

The Trigon 80° form and 0.4 mm corner radius balance strength and form detail for general finishing and light semi-finishing passes. A 7° relief angle reduces rubbing while maintaining edge support under radial and axial loads, which helps to lower cutting temperatures and micro-chipping. The compact plate dimensions (size 03, thickness 02) make the insert suitable for tight-pocket toolholders and versatile turning fixtures, while the trigon shape offers three usable cutting edges for economical indexing. These geometric choices translate into stable cutting forces and improved surface integrity on difficult alloys.

Chip control, process security and shop-floor advantages

The FM2 chipbreaker is tuned for forming and evacuating chips when machining sticky, work-hardening materials. Stable chip formation reduces the risk of build-up on the cutting edge and limits secondary thermal loading, thereby extending effective tool life. With tolerance class G and repeatable seating geometry, the insert contributes to predictable assembly and interchangeability across toolholders. For production engineers this means fewer interruptions, more reproducible cycle times and a clearer path to process optimisation when working with rostfreier Stahl and titanium-alloy components.
