DCMT070204 GH730 – Tungaloy turning insert (ISO rhombic 07, 0.4 mm radius, 7° clearance)

The DCMT070204 GH730 is an ISO rhombic indexable insert engineered for external and internal turning, offering a balance of wear resistance and edge stability for general to finishing turning applications

• Wear-resistant GH730 grade
• 0.4 mm corner radius for fine finishes
• 7° clearance for secure cutting
• Cylindrical hole with single-sided countersink

Consistent machining and extended tool life

The GH730 carbide grade is formulated to combine wear resistance with sufficient toughness, reducing edge breakdown during interrupted cuts and longer production runs. By choosing an insert matched to the operation, the machining process becomes more predictable and cycle times remain stable. The ISO-designation ensures straightforward interchangeability within standard toolholder systems, making inventory management simpler and reducing downtime caused by tool changeovers.

Secure clamping and accurate cutting geometry

The rhombic 07 form and 0.4 mm corner radius enable finer surface finishes while maintaining edge strength for light to medium cuts. A 7° clearance angle supports reliable chip evacuation and lowers rubbing on the flank face, contributing to consistent dimensional results. The insert features a cylindrical hole with a single-sided countersink (40°–60°) for positive, repeatable clamping in compatible holders; the 2.38 mm plate thickness provides rigidity to resist chatter in typical turning setups.

Practical selection advice for process reliability

Select the appropriate chipbreaker and grade based on the workpiece material and machining stability: a single-sided chipbreaker suits many standard turning tasks, while the carbide composition provides a compromise between wear life and toughness. For applications where surface finish and edge consistency are crucial, the small corner radius and GH730 behaviour help deliver the necessary results.
