TCGT16T308-MN2 WNN10 indexable insert — triangle 60°, MN2 chipbreaker | Walter Tools

TCGT16T308-MN2 WNN10 is a coated carbide indexable insert intended for turning and boring operations where stable chip formation and predictable tool life are required

• WNN10 coated carbide for wide applicability
• Chipbreaker MN2 for controlled chip formation
• Triangle 60° form with 0.8 mm corner radius
• 7° clearance and T3 thickness for stable contact

Consistent chip control that improves cycle stability

The combination of a coated carbide grade and the chipbreaker MN2 provides reliable chip segmentation across a range of cutting conditions. The coated substrate is engineered to reduce adhesion and wear, while the MN2 geometry shapes chips to evacuate cleanly from the cutting zone. For production environments this means fewer interruptions caused by tangled chips, improved process stability and a reduction in manual rework. The technical design therefore supports higher machine uptime and predictable component quality.

Geometry engineered for strength and surface finish

The triangle 60° shape with a 0.8 mm corner radius balances cutting-edge durability and surface quality. A larger corner radius increases edge strength and reduces the likelihood of chipping under interrupted cuts, while still enabling fine surface finishes when light radial engagement is applied. The 7° clearance angle minimises flank contact and the T3 thickness contributes to secure seating in compatible toolholders. Together, these geometric choices deliver repeatable performance where consistent dimensional accuracy is required.

Flexible integration into turning and boring toolholders

Designed as a combined turning and boring insert, the component integrates with standard clamping systems that accept triangular inserts. The tolerance class G and the 16 mm plate size simplify selection of compatible toolholders and help ensure stable clamping forces during heavy cuts. The insert’s designation identifies its chipbreaker and grade, enabling straightforward pairing with holder types specified for triangle 60° inserts and providing a practical path to retrofit or expand existing tool sets without extensive retooling.

Coating and grade insights for reliable wear resistance

The WNN10 grade is a coated carbide formulation developed for broad material coverage and predictable wear behaviour. Coatings reduce friction at the cutting edge and extend flank life under varied cutting conditions; the underlying carbide substrate sustains the mechanical loads typical in roughing and finishing passes. For specific workpiece materials and optimal cutting data, consult the manufacturer’s product matrix to match grade performance to the intended application and achieve consistent tool life.

Practical considerations for selection and handling

When selecting this insert, verify holder compatibility, clamping orientation and the recommended insert seat geometry. Replace inserts at the first signs of edge chipping or progressive flank wear to maintain part tolerances and surface quality. Storage in a dry, protected environment and using correct torque values for the clamping screws will preserve the insert’s integrity and help to achieve the repeatable performance expected from Walter Tools cutting solutions.
