EPGT040102 SH7025 Tungaloy insert — ISO rhombic turning insert, 75° cutting angle

A EPGT040102 SH7025 Tungaloy insert for ISO‑standard external and internal turning, engineered to offer edge stability in small‑tool setups and variable engagement conditions

• SH7025 coated carbide grade
• ISO rhombic insert size 04, 75° cutting angle
• 0.2 mm corner radius for fine finishes
• Cylindrical hole with single-side countersink

Durable grade for varying engagement conditions

The SH7025 designation identifies a coated cemented carbide grade developed for toughness and edge stability. In practice, this means the insert sustains cutting forces in situations with fluctuating chip load or interrupted cuts, especially when used in smaller toolholders. The combination of a resilient substrate and a protective coating reduces flank wear and helps maintain repeatable tool life, supporting continuous production or small‑batch runs where consistent performance is required.

Geometry designed for precision and holder compatibility

The rhombic plate shape with ISO code 040102 and a nominal cutting angle of 75° ensures predictable cutting vectors for conventional turning operations. The insert’s 11° clearance angle and the 1.59 mm plate thickness contribute to stable seating in the pocket and reliable chip flow. Compatibility with ISO‑standard holders is determined by form, clearance, tolerance class, fastening style, size and thickness; selecting a matching holder and clamp set ensures accurate alignment and repeatable results in serial machining.

Fine finishing and secure clamping for improved surface quality

A 0.2 mm corner radius provides a balance between edge strength and the ability to achieve fine surface finishes on external and internal features. The single‑sided chipbreaker is optimised for specific cutting conditions and, when matched to workpiece material and machining parameters, promotes compact chips and stable cutting. The cylindrical hole with single‑side countersink (40°–60°) facilitates secure clamping with replacement screws and underlay kits, reducing the risk of micro‑movement and improving dimensional consistency across batches.

Practical application notes and selection guidance

This insert is intended for turning applications where variable engagement or small‑tool geometries are present; choose the chipbreaker and cutter grade according to the workpiece material, operation and machine stability. When replacing inserts, confirm holder compatibility by checking form and tolerance class, and use the specified underlay and clamping set for repeatable seat height. For tailored parameter recommendations or if clarification is required regarding suitability for a given task, refer to Metav Werkzeuge’s technical advisers or provide the operative conditions for an informed selection.

For robust, repeatable turning with Tungaloy’s SH7025 grade, request the EPGT040102 insert from Metav Werkzeuge or contact our consultants at Metav Werkzeuge for application support and ordering assistance.

FAQ

What operations is this insert suited for?
The EPGT040102 SH7025 Tungaloy insert is designed for external and internal turning where edge stability and toughness are needed, particularly in small‑tool setups or changing engagement conditions.

How does the SH7025 grade influence tool life?
SH7025 is a coated cemented carbide grade that promotes stable edge behaviour under variable loads, helping to delay flank wear and extend the useful life of the insert in many turning applications.

What must be checked to ensure holder compatibility?
Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and thickness; confirm these parameters with the chosen ISO‑standard holder before assembly.

Can this insert achieve fine surface finishes?
Yes — the 0.2 mm corner radius and the plate geometry support fine finishing when combined with suitable cutting parameters and a properly matched chipbreaker.
