EPGT040102 SH730 Tungaloy indexable turning insert — turning, rhombic 04, ISO 040102

The EPGT040102 SH730 Tungaloy insert is an ISO rhombic indexable insert engineered for external and internal turning, offering stable cutting-edge performance and dependable chip control in variable engagement conditions.

• SH730 grade for stable cutting edges
• Rhombic 04 geometry, 75° cutting angle
• 0.2 mm corner radius for fine finishing
• Single-sided chipbreaker with centre hole

Proven grade for consistent productivity

The coated cemented carbide SH730 grade combines toughness with cutting-edge stability, designed to maintain edge integrity under fluctuating cutting conditions. This specification supports productive turning cycles and reduces downtime caused by unexpected edge failures. As a result, workshops benefit from improved process reliability and steady part quality when machining steels and mixed batches where tool engagement varies. The composition and coating technology provide a balance between wear resistance and shock tolerance, making this insert suitable for demanding, production-oriented environments.

Geometry and chip control that protect surface quality

The rhombic 04 shape with a 75° approach and 11° relief offers a versatile cutting geometry that improves insert life and surface finish in both external and internal turning operations. The single-sided chipbreaker and the central hole with a cylindrical bore plus a single-sided countersink (40°–60°) support secure locating and repeatable clamping, reducing vibration and supporting controlled chip flow. A 0.2 mm corner radius helps achieve finer finishes and tighter tolerances, especially on smaller-diameter tools. Compatibility with holders is determined by form, clearance angle, tolerance class, fastening method, size and plate thickness.

System compatibility and workshop handling to ease assembly

The insert is supplied in the ISO series format and integrates into standard clamping systems consisting of a matching external holder or boring bar, support shim/clamping set and replacement screws. With a 1.59 mm plate thickness and a centred hole, the component offers straightforward retrofit into existing toolrooms where ISO indexable tooling is used. The SKU and manufacturer article number simplify reordering and inventory management, while the grade choice and chipbreaker type guide selection for specific materials and cutting strategies. For small tools or frequently changing engagement, this insert’s balanced design aids consistent machining results.

FAQ

What materials is this insert suitable for?
The EPGT040102 SH730 insert is specified for general turning tasks and performs well on a wide range of steels and mixed batches owing to the tough SH730 grade.

Which holders are compatible with the insert?
Compatibility requires a matching ISO rhombic holder designed for 04-size plates; holder selection must account for form, clearance angle, tolerance class, fastening method and plate thickness.

How does the chipbreaker affect performance?
The single-sided chipbreaker on this insert provides controlled chip formation and evacuation, which helps to stabilise cutting forces and improve surface finish during turning.

Can the insert be used for internal boring?
Yes, the rhombic geometry and the 75° cutting angle support both external and internal turning when paired with a suitable boring bar and proper clamping.

What is the significance of the 0.2 mm corner radius?
A 0.2 mm corner radius balances finishing capability with edge strength, allowing finer surface finishes while maintaining robustness in many turning operations.
