TCGT090202-FN2 WNN10 – Triangular 60° Turning/Boring Insert by Walter Tools, 7° Relief, 0.2 mm Radius

The TCGT090202-FN2 WNN10 is a triangular indexable insert intended for turning and boring applications, engineered to provide controlled chip formation and repeatable edge performance in production environments.

• Coated carbide grade WNN10
• Triangular 60° geometry
• 0.2 mm corner radius for fine finishing
• FN2 chipbreaker for controlled chips

Stable cutting performance that protects cycle times

The insert's coated carbide grade WNN10 is formulated as a general-purpose, coated hardmetal option that emphasises reliable wear resistance and consistent cutting behaviour. The combination of the coating and substrate aims to deliver stable chip formation, which reduces unexpected interruptions in automated cycles and helps maintain spindle productivity. The presence of a dedicated chipbreaker FN2 improves evacuative behaviour for a range of cutting depths and feeds; this means fewer manual interventions and a reduced risk of edge damage during interrupted cuts. In practice, the result is more predictable tool life and a steadier production flow.

Geometry designed for accuracy and surface quality

The triangular 60° shape, together with a 7° relief angle, provides a balance between edge strength and access into tight profiles. The small corner radius 0.2 mm enables improved surface finish on light finishing passes while still retaining sufficient edge robustness for general turning and boring tasks. The geometry aids in achieving repeatable tolerances without unnecessary overcutting; a smaller radius supports finer finishes, whereas the 60° form provides multiple indexed cutting edges for economical use. Replacement and indexing are straightforward, reducing machine downtime and speeding up tool change procedures.

Application advice and selection guidance

The insert belongs to the Walter Schneidstoffsorte – Serie offen and is identified as TCGT090202-FN2 WNN10, with material assignment listed as catalogue-dependent; therefore material suitability must be checked against the manufacturer's product matrix. The execution T, tolerance class G and plate dimensions (plate size 09, thickness 02) define the mechanical fit and interchangeability within matching toolholders. For customers seeking process optimisation, the insert supports strategies that prioritise consistent chip control and reproducible edge life rather than aggressive finishing at single-pass maximum metal removal.

FAQ

What cutting tasks is this insert intended for?
The TCGT090202-FN2 WNN10 is intended for turning and boring operations where reproducible chip control and predictable edge life are priorities.

How does the FN2 chipbreaker influence operation?
The FN2 chipbreaker promotes controlled chip formation and evacuation, improving process stability and reducing the likelihood of recut or chip-related interruptions during machining.

What does the 0.2 mm corner radius mean for surface finish?
A corner radius of 0.2 mm supports finer surface finishes on light finishing passes while maintaining sufficient edge strength for common turning tasks.

Is the grade WNN10 suitable for all materials?
The WNN10 grade is a coated hardmetal option; material compatibility should be verified against the manufacturer's product matrix for precise recommendations.

Which toolholders are compatible with this insert geometry?
Toolholders designed for triangular 60° inserts with plate size 09 and plate thickness 02 will be mechanically compatible; check holder specifications for matching seat and clamping features.
