DNMG 110404 T9215 turning indexable insert by Tungaloy — CVD-coated carbide, 55° rhombic

The DNMG110404 T9215 is an ISO rhombic turning insert designed for external and internal turning of medium steel, offering a balance of wear resistance and fracture toughness for continuous to light interrupted cuts

• CVD-coated carbide grade T9215
• Rhombic 55° ISO geometry
• 0.4 mm corner radius
• Double-sided chipbreaker, with cylindrical hole

Consistent productivity through robust cutting material and geometry

The combination of CVD-coated carbide and the T9215 grade delivers a high level of wear resistance while maintaining fracture toughness, making the insert particularly suited to medium steel machining where stable cutting and long tool life are priorities. The rhombic 55° geometry provides reliable approach angles for both facing and turning operations, helping to sustain cutting forces and reduce vibration. As a result, cycle times can be optimised and tool-change frequency reduced, supporting continuous production environments and improving overall throughput.

Predictable integration with ISO tooling systems

Compatibility depends on established parameters such as form, clearance angle (0°), tolerance class, fastening method, size and thickness. The insert follows ISO conventions and is intended to be used with a matching external holder or boring bar, plus a suitable shim and clamping set. Specifying the correct holder geometry and fastening hardware ensures accurate seating and repeatable positioning, which in turn secures part tolerances and surface quality. The insert's cylindrical hole and standard dimensions facilitate straightforward replacement within existing tool systems.

Reliable chip control and surface finish for turning applications

Equipped with a double-sided chipbreaker, the insert supports effective chip formation and evacuation during both external and internal turning. This feature improves chip control and reduces the risk of built-up edge, particularly in continuous cuts. For medium steels the grade and chipbreaker combination help to deliver consistent surface finishes while allowing reasonable cutting parameters to be applied. Selection of the correct chipbreaker and cutting conditions will further enhance performance in light interrupted cuts and during step-down operations.

Operational benefits and selection guidance for workshop use

The compact 0.4 mm corner radius provides a balance between strength at the cutting edge and the ability to achieve close tolerances and fine finishes on turned components. The insert is suitable where a combination of productivity and predictable service life is required; selecting the matching chipbreaker and holder stability will determine achievable feed and depth parameters. Technical consultation is advisable for optimised parameter selection when introducing the insert into new machines or processes to ensure the best compromise between cycle time, finish and insert life.
