TNMG220412 T5115 indexable insert for turning — 60° triangle, 1.2 mm nose radius — Tungaloy

A TNMG220412 T5115 indexable carbide insert designed for external and internal turning, offering a universal grade for cast iron with balanced wear resistance and reliable cutting-edge stability

• CVD-coated carbide T5115 for cast iron
• ISO-standard triangular insert, 60° included angle
• 1.2 mm nose radius for stable turning results
• Double-sided chipbreaker, hole for secure clamping

Consistent machining through proven coating and substrate

The combination of a CVD coating and a carbide substrate provides a wear-resistant cutting edge that is especially suited to cast-iron applications. The specified T5115 grade is a universal formulation that balances wear resistance and edge stability, which translates into fewer unscheduled insert changes and more consistent component tolerances. Because the coating reduces abrasive adhesion and the substrate maintains toughness, cycle times can be stabilised and tool life extended under typical turning conditions.

Geometry and clamping designed for predictable results

A triangular insert with a 60° included angle and a 1.2 mm nose radius gives a good compromise between strength and surface finish: the corner radius supports stable cutting forces while the geometry remains versatile for a range of turning profiles. The insert is ISO-standard, which ensures compatibility with common indexable holders and boring bars when the holder selection matches form, clearance angle, tolerance class, fixing method, size and thickness. The double-sided chipbreaker extends usable life by permitting indexation of both faces, while the cylindrical hole enables secure location and clamping in standard carrier systems.

System-level benefits and application guidance

This insert is intended for use within a complete system comprising the insert, a suitable external holder or boring bar, an underlay/clamp set and replacement screws. For external and internal turning, selecting the correct chipbreaker and grade relative to the workpiece material and machining stability is essential; the included chip control solution is optimised for cast iron but can be matched to different machining strategies. The nominal plate thickness of 4.76 mm, combined with the triangular form, supports rigid clamping and vibration resistance, which helps preserve edge integrity and surface quality during finishing passes.
