EPGT 040101 SH7025 ISO rhombic turning insert by Tungaloy — 75° cutting geometry, 11° relief

The EPGT 040101 SH7025 is an ISO-standard rhombic turning insert designed for general external and internal turning applications where a tough, edge-stable grade is required.

• Coated carbide grade SH7025
• Rhombic 04 geometry, 75° cutting angle
• 0.1 mm corner radius
• Cylindrical hole with 40°–60° countersink

Durable grade optimised for variable engagement

The coated carbide designation SH7025 denotes a tough, edge-stable cutting grade developed for turning tasks where tool engagement can vary. This composition improves resistance to chipping during interrupted cuts and supports reliable performance on smaller tools. By combining a robust substrate with a protective coating, the insert delivers extended tool life and lower machining costs per part, making it a rational choice for production environments that value predictable wear behaviour and long tool cycles.

Geometry and relief that support secure clamping and precise cutting

The rhombic 04 form with a 75° cutting angle and an 11° relief angle provides a balance between strength and accessibility in confined turning operations. The modest 0.1 mm corner radius aids in producing consistent surface quality while reducing the risk of premature edge failure. The insert’s cylindrical hole with a single-side countersink (40°–60°) ensures accurate seating and repeatable clamping forces when used with compatible ISO holders. These geometry features translate into stable cutting conditions, improved process reliability and easier tool changeover during batch production.

Practical system compatibility and chip control for efficient turning

Compatibility with the toolholder depends on form, relief angle, tolerance class, fastening arrangement, size and thickness; this insert is intended to be integrated into a system consisting of the ISO insert, a matched external holder or boring bar, a seating/clamp set and replacement screws. The single-sided chipbreaker directs chips away from the cutting zone, reducing recutting and facilitating chip evacuation — a clear operational benefit for improving cycle times and reducing manual post-process handling. For flexible operations where cutting conditions change, selecting the correct combination of chipbreaker and grade helps secure consistent production results.

FAQ

What machining tasks suit this insert best?
The EPGT 040101 SH7025 insert is designed for external and internal turning where a tough, edge-stable grade is required, particularly in operations with variable engagement or smaller tooling.

How does the insert’s geometry affect performance?
The rhombic form with a 75° cutting angle and 11° relief provides strength and access in turning, while the 0.1 mm corner radius supports consistent surface finish and reduced risk of edge chipping during interrupted cuts.

How is compatibility with holders determined?
Compatibility depends on the insert’s form, relief angle, tolerance class, fastening, size and thickness; correct pairing with ISO holders, clamp sets and screws is essential for repeatable clamping and process stability.

What benefit does the single-sided chipbreaker provide?
The single-sided chipbreaker on this insert improves chip control and evacuation, which reduces recutting and can shorten cycle times while enhancing operator safety and part quality.
