EPGT040104 SH7025 indexable turning insert — rhombic 04, 11° clearance (Tungaloy)

The EPGT040104 SH7025 is an ISO‑format indexable turning insert designed for external and internal turning operations, offering a tough, edge‑stable coated carbide grade for variable engagement conditions.

• ISO rhombic 04 form, 11° clearance
• SH7025 coated carbide, edge‑stable grade
• Single‑sided chipbreaker, hole with countersink
• Compatible with standard ISO turning holders

Stable cutting edges for mixed and intermittent turning

The coated carbide SH7025 grade delivers a balance between toughness and wear resistance, making it suitable where engagement conditions change or where smaller tools are used. The combination of a 0.4 mm corner radius and a robust coating supports consistent edge life and reduces the risk of chipping during interrupted cuts. This results in fewer insert changes and steadier process outputs, which is particularly relevant for batch production and jobs with variable cut depths.

Predictable fit and simple retrofitting to existing holders

Made to the ISO series specification, the insert’s rhombic 04 form and defined geometry ensure reproducible seating in compatible toolholders. Holder compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness, so selecting a holder that matches these parameters guarantees correct clamping and stable cutting. The central cylindrical hole with a one‑sided countersink (40°–60°) simplifies secure fastening and repeatable indexing of the cutting edge.

Controlled chip formation for cleaner surfaces

The one‑sided chipbreaker design encourages orderly chip control in typical turning applications, improving evacuation and reducing the chance of built‑up edge. Combined with the insert’s 1.59 mm thickness, the geometry supports adequate rigidity for finish and semi‑finish turning, delivering improved surface integrity and dimensional consistency with fewer reworks.

Practical geometry for versatile turning tasks

The 11° clearance angle and the insert’s overall geometry permit flexible use on both external and internal turning operations. The compact 04 size is advantageous where access is limited or where multiple indexed corners are required from a single insert. As a purpose‑designed ISO insert, it integrates into standard tooling systems and supports efficient tool management through straightforward rotation and replacement.

FAQ

What turning tasks is this insert designed for?
The EPGT040104 SH7025 insert is designed for both external and internal turning, offering versatility for finish and semi‑finish operations where stable edges and good chip control are required.

Which materials suit the SH7025 grade?
The SH7025 coated carbide is a tough, edge‑stable grade intended for a wide material range; the actual choice of chipbreaker and cutting parameters should match the workpiece material and machining conditions when using this insert.

How can compatibility with existing holders be ensured?
Compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness; verifying these parameters against the holder specification ensures correct seating of the insert.

Why is the 0.4 mm corner radius important?
A 0.4 mm corner radius increases edge strength and contributes to improved surface finish, helping the insert withstand light shock and maintain dimensional stability during turning.

Is the insert indexed and easy to replace?
Yes, the ISO‑formatted geometry, central hole and countersink facilitate secure clamping and straightforward indexing, enabling efficient replacement during production.
