TCGT110202-MN2 WNN10 indexable insert for boring and turning — Walter Tools, coated carbide, MN2 chipbreaker, triangular 60°

TCGT110202-MN2 WNN10 is a coated-carbide indexable insert designed for versatile boring and turning operations in production environments

• Triangular 60° form for multi-edge use
• Coated carbide grade WNN10 for broad applications
• MN2 chipbreaker for controlled chip formation
• 0.2 mm corner radius for fine finishing

Maximising process reliability with an engineered insert design

The triangular insert offers a compact cutting geometry that supports repeatable tool engagement and reduced downtime. Thanks to the 60° triangle and the MN2 chipbreaker, chip formation is controlled, lowering the risk of built-up edge and improving swarf evacuation. This leads to a more predictable machining process and fewer interruptions. The combination of the WNN10 coated-carbide grade and the insert geometry supports a stable cutting edge, which is especially beneficial in series production where consistency and tool life are decisive.

Coated-carbide grade WNN10: balanced wear resistance and versatility

The WNN10 grade is a coated carbide class chosen for broad workpiece compatibility; the coating increases resistance to abrasive wear while maintaining a sharp cutting edge. For many common turning and boring tasks this means longer tool life and more consistent surface quality, reducing rework and machine idle time. Operators unfamiliar with carbide grades can consider WNN10 as a general-purpose, productive option — check the product matrix for exact material matches and cutting data to ensure optimal use.

Geometry details that benefit surface finish and accuracy

Key geometry parameters are engineered to influence the cutting result: the 0.2 mm corner radius supports fine finishing and helps achieve tight dimensional tolerances, while the 7° clearance angle reduces rubbing and promotes smooth cutting action. The insert’s compact size and 2.0 mm thickness (standard for this designation) enable secure clamping and minimise vibration in light to medium-duty turning and boring operations, which in turn enhances the achievable surface quality and repeatability.

Practical application advice and selection notes

When selecting this type of insert, choose the MN2 chipbreaker for operations where consistent small chips and stable forces are required; it is well suited to semi-finishing and finishing passes. The insert’s triangular form offers multiple indexable cutting edges, helping to lower tooling cost per part. For unfamiliar materials or critical components, consult the manufacturer’s product matrix to verify that WNN10 is the recommended grade for the specific workpiece material and machining parameters.

FAQ

Which materials is this insert suited for?
The insert in the TCGT110202-MN2 WNN10 designation is intended for a broad range of materials; the WNN10 coated-carbide grade is versatile, but the product matrix should be consulted to confirm suitability for a specific workpiece material.

How does the MN2 chipbreaker affect machining?
The MN2 chipbreaker promotes controlled chip formation and evacuation, resulting in more stable cutting forces and improved process reliability for semi-finishing and finishing cuts.

What does the 0.2 mm corner radius mean for surface finish?
A 0.2 mm corner radius helps to achieve finer surface quality and better dimensional control during finishing passes, with reduced risk of edge chipping compared with sharper radii.

Can this insert be indexed multiple times?
The triangular 60° form provides multiple cutting edges, allowing several indexing operations per insert and reducing tooling cost per effective cutting edge.

Is WNN10 suitable for high-speed machining?
WNN10 is a coated-carbide grade designed for productive machining; for specific high-speed applications, verify recommended cutting speeds and parameters in the product matrix.
