EPGT 040104 SH7025 turning insert (EPGT040104) by Tungaloy – coated carbide, ISO 040104, 75° rhombic

The EPGT040104 SH7025 is an ISO-standard turning insert engineered for external and internal turning where edge stability and repeatable results are required in variable engagement conditions.

• Coated carbide grade SH7025 for edge stability
• 75° rhombic insert, ISO 040104 form
• 0.4 mm corner radius for precise profiles
• Single-sided chipbreaker, with central hole

Boosted productivity through stable edge life and predictable chip control

The primary benefit of the SH7025 grade is its focus on edge stability under changing cutting conditions. As a coated carbide insert, it is designed to maintain a durable cutting edge even when smaller tools or varying engagement depths are used. The single-sided chipbreaker is tailored to promote consistent chip formation, reducing interruptions and enabling more continuous cycles in turning operations. Compatibility with standard clamping systems is determined by form, relief angle, tolerance class, fixing method, size and thickness; these factors ensure the insert can be integrated into existing toolholders without compromising process reliability.

Consistent component quality thanks to precise geometry and ISO standardisation

The 75° rhombic geometry combined with the ISO 040104 designation provides a familiar form factor for many turning applications, supporting accurate profile generation and angular approaches. The 0.4 mm corner radius gives controlled cutting edge engagement for profile accuracy while limiting stress concentrations at the cutting tip. With a plate thickness of 1.59 mm, the insert offers a balance between rigidity and favourable cutting access in confined or fine-detail turning tasks. In practice, this geometry supports repeatable surface finishes and dimensional stability when matched to appropriate machining parameters.

Practical integration and handling for workshop efficiency

Integration into a turning system is straightforward: the insert sits in a matching outer holder or boring bar and is secured with the required clamp and screw set; a small central hole with a cylindrical bore plus a single-sided countersink (40°–60°) facilitates accurate seating and positive clamping. The insert series is used together with a suitable holder, underlay/clamping kit and replacement screws to form a complete cutting unit. Selection of the correct chipbreaker and grade should be based on workpiece material and process stability; where material varieties or entry conditions change frequently, the SH7025 grade is advantageous for its toughness and resistance to chipping, supporting fewer tool changes and higher uptime.

FAQ

What materials is this insert suitable for?
The EPGT040104 SH7025 insert is a coated carbide grade engineered for a broad range of turning tasks; selection of the chipbreaker and operating parameters should be matched to the specific workpiece material for optimal results.

How is the insert clamped and located in the holder?
The insert features a central hole with a cylindrical bore and a single-sided countersink (40°–60°) for positive seating; it is used with a matching outer holder or boring bar together with an underlay/clamping kit and replacement screws.

Can the SH7025 grade be used for interrupted cuts?
The SH7025 grade offers increased toughness and edge stability, making it suitable for applications with variable engagement or moderate interruptions, particularly when smaller tools are involved.

What benefits does the 0.4 mm corner radius provide?
A 0.4 mm corner radius balances profile accuracy and tool strength, enabling precise profiles while reducing the likelihood of edge chipping during typical turning operations.

Which ISO form does this insert conform to and why is that important?
The insert is listed as ISO 040104 (EPGT040104), which ensures compatibility with holders designed for that form and simplifies tool selection and replacement across standardised tool systems.
