DCMT 070204 GH730 – Indexable turning insert (Tungaloy, ISO)

The DCMT070204 GH730 is an ISO-standard indexable turning insert designed for external and internal turning, providing a balance of wear resistance and cutting-edge stability.

• ISO-standard rhombic insert
• GH730 grade for wear resistance
• One-sided chipbreaker for controlled chips
• 0.4 mm corner radius, 7° clearance

Durable carbide grade for longer cutting life

The insert is produced in a carbide composition with the GH730 grade, engineered to combine wear resistance and edge stability. This results in reduced flank wear and more consistent part tolerances over longer tool life, so fewer interruptions for insert changes are required. The grade complements the insert geometry to withstand varying cutting loads while maintaining a reliable cutting edge, which supports predictable cycle times and reduces overall tooling costs in production environments.

Precise fit and straightforward integration into ISO tool systems

Designed to ISO dimensions, the rhombic indexable insert fits a wide range of holders when matching form, clearance angle and thickness. The combination of 2.38 mm thickness, rhombic shape and the with-hole design featuring a cylindrical hole plus a single-side countersink (40°–60°) ensures secure clamping and reproducible seating. The listed 7° clearance and 0.4 mm corner radius help to define the contact geometry and cutting line, enabling consistent results across repeated indexings and minimising setup rework when replacing inserts in compatible holders.

Consistent chip formation and effective turning performance

A built-in one-sided chipbreaker provides controlled chip formation, improving swarf evacuation and reducing the risk of re-cutting. This contributes to more stable cutting forces and better surface finish in typical turning operations. The insert’s geometry supports both external and internal turning tasks where a predictable chip pattern and robust edge are essential, particularly in automated or series production. The system approach—insert, compatible external holder or boring bar, backing plate/clamping set and replacement screws—ensures operational reliability and straightforward replacement procedures.

FAQ

What materials is this insert intended for? The DCMT070204 GH730 indexable insert is specified for turning operations; the GH730 grade is formulated to provide a balance of wear resistance and edge stability suitable for a broad range of turning conditions.

How does the insert locate in the holder? Location is achieved by the ISO-standard form and the central hole with cylindrical seat and single-side countersink; correct holder matching to the insert form, clearance angle and thickness is essential for secure clamping.

What is the advantage of the one-sided chipbreaker? The one-sided chipbreaker of the insert ensures controlled chip formation, improving swarf evacuation and contributing to stable cutting forces and a consistent surface finish during turning.

Can this insert be used for internal turning? Yes, the insert is designed for both external and internal turning applications when fitted to an appropriate external holder or boring bar and clamped with the correct backing plate or clamping set.

How is the corner radius relevant to my machining? The 0.4 mm corner radius influences the strength of the cutting edge and the surface finish; a small radius like 0.4 mm helps achieve a compromise between edge robustness and finer surface quality for many turning tasks.
