TNMU 1207R2 T1215 — TNMU indexable milling insert for milling, 60° included angle (Tungaloy)

The TNMU 1207R2 T1215 is a triangular, indexable insert designed for Tungaloy milling systems, offering robust edge stability and a balance of wear resistance and toughness for a wide range of milling operations.

• TNMU1207R2 T1215 carbide grade
• Triangle 12 mm insert, 60° included angle
• Double-sided chipbreaker for controlled chips
• Cylindrical hole with double countersink 40°–60°

Consistent cutting performance through material and geometry

The grade T1215, applied to a cemented carbide substrate, provides a defined compromise between hardness and toughness that supports longer tool life and predictable wear behaviour. Combined with the triangular shape and 60° included angle, the insert supplies stable cutting conditions for operations where edge security is essential. The 7.94 mm plate thickness contributes to rigidity, reducing vibration in heavy cuts and helping to maintain surface finish and dimensional accuracy over extended cycles.

Secure seating and system compatibility to reduce setup errors

Designed specifically for matching Tungaloy milling systems, the insert requires a compatible insert seat, clamp screw and milling body; correct combination ensures repeatable clamping and safe operation. The cylindrical hole with a double-sided countersink (40°–60°) centres the insert and increases clamping reliability, while the 0° relief angle supports full-face contact in the pocket. Technical matching of seat geometry avoids micro-movement and minimises the risk of edge chipping during interrupted cuts.

Productivity benefits in typical milling applications

With a double-sided chipbreaker, the insert controls chip formation for improved evacuation and stable cutting forces, which supports higher material removal rates and smoother finishing in face, shoulder, slot, high-feed and contour milling depending on the chosen tool family. The triangular form delivers three indexable cutting edges per insert, making the solution economical for batch production and maintenance of throughput. The grade complements the insert geometry by enhancing wear resistance, toughness and cutting-edge stability, resulting in reliable performance across demanding production cycles.

FAQ

What is the main advantage of the T1215 grade?
The T1215 grade on the TNMU 1207R2 provides a balance of wear resistance and toughness, supporting stable cutting-edge life for milling applications.

How many usable cutting edges does this insert provide?
As a triangular indexable insert, the TNMU 1207R2 offers three usable cutting edges per insert, enabling rapid indexing and economical edge replacement.

How does the hole and countersink design improve performance?
The cylindrical hole with a double-sided countersink (40°–60°) on the TNMU 1207R2 ensures central seating and improved clamping stability within compatible Tungaloy milling bodies.

Which milling operations suit this insert?
The insert is suited to face, shoulder, slot, high-feed and contour milling when paired with the correct tool family and body; selection depends on the specific toolholder and cutting parameters.

Is the insert compatible with other manufacturers’ milling bodies?
Compatibility requires identical seat geometry and clamping method; the TNMU 1207R2 is intended for use in Tungaloy milling systems and must be checked against any alternative body design.
