CNMG120412 T5115 turning insert (ISO, rhombic, 80°) by Tungaloy

CNMG120412 T5115 is an ISO-format turning insert designed for external and internal turning applications, offering a universal grade for cast iron with stable cutting-edge performance

• CVD-coated carbide grade T5115
• Universal grade for cast iron
• Double-sided chipbreaker
• ISO rhombic form, 80° geometry

High wear resistance for longer uninterrupted production

The combination of CVD-coated carbide and the T5115 grade provides a reliable balance between wear resistance and edge stability, suitable for continuous machining of cast iron. CVD (chemical vapour deposition) delivers a hard, adherent coating layer that reduces abrasive wear and temperature-related edge breakdown; this translates into fewer insert changes and more productive cutting cycles. The universal grade is formulated to manage a range of cast-iron microstructures, so the component life of the cutting edge is extended while maintaining consistent surface quality.

Consistent chip control and reduced rework

A double-sided chipbreaker integrated into the insert geometry promotes predictable chip formation and evacuation, which is essential when machining interrupted or heavy cuts. Effective chip control reduces the risk of surface damage and tool collisions, contributing to improved first-pass yield and less post-process finishing. The rhombic shape and 80° main cutting-edge angle help distribute cutting forces evenly, supporting stable turning operations and steady feed behaviour under varying depths of cut.

Seamless fit into ISO turning systems for quick set-up

The rhombic plate with a cylindrical locating hole, a plate thickness of 4.76 mm and a corner radius of 1.2 mm matches standard ISO clamping systems; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness. The 0° clearance angle and the ISO sizing simplify tool selection and replacement in modular toolholders, reducing set-up time and ensuring repeatable positioning. Where required, the system includes a suitable underlay or clamping set and replacement screws to restore clamping accuracy quickly.

FAQ

What materials is this insert best suited for? This insert is optimised for cast iron work; the T5115 CVD-coated carbide grade offers a balance of wear resistance and edge stability for a wide range of cast-iron grades.

Is the insert reversible and usable on both sides? Yes, the plate is double-sided with a chipbreaker on each cutting edge, allowing rotation and reuse of the second side to extend usable life.

Which geometry should be checked for holder compatibility? Check form, clearance angle, tolerance class, fastening type, insert size and thickness for compatibility; the CNMG120412 format follows ISO dimensions and uses a cylindrical locating hole.

What benefits does the 80° rhombic form provide in turning? The 80° geometry provides strength on the cutting edge and good access for finishing passes, helping to maintain dimensional control and surface quality during external and internal turning.
