EPGT 040101 SH7025 – coated carbide turning insert (ISO) by Tungaloy

EPGT040101 SH7025 is an ISO-standard rhombic indexable insert developed for external and internal turning, offering a resilient cutting edge suited to variable engagement conditions.

• ISO-standard rhombic insert, size 04
• Coated carbide grade SH7025 for stable edges
• 0.1 mm corner radius for fine turning
• Cylindrical hole with 40–60° countersink

Proven cutting performance under changing conditions

The SH7025 coated carbide grade delivers a tough, edge-stable performance that is particularly effective in smaller tool assemblies and when engagement conditions vary. This composition reduces the frequency of edge deterioration and supports a more consistent surface finish, which in turn lowers the number of tool changes and idle times on the shop floor. The result is a measurable increase in process uptime and predictable component quality, especially in medium- to high-volume turning operations.

Geometry designed for reliable clamping and accessibility

A rhombic 04 form with a 75° main angle and a 0.1 mm corner radius provides a balance between profile accuracy and cutting robustness. The insert’s 11° clearance angle and 1.59 mm thickness support stable seating in compatible holders, while the cylindrical hole with single-sided countersink (40°–60°) ensures secure clamping and correct axial positioning. These geometric details make indexing straightforward and maintain repeatable cutting lines, which is essential when switching between holders or when tight tolerances are required.

Simple system integration for turning tasks

As an ISO indexable component, the insert integrates into a system comprising a matching external holder or boring bar, a backing shim or clamp set, and standard replacement screws. The single-sided chipbreaker supports controlled chip formation for turning applications, and the grade selection should be matched to workpiece material and machining stability for best results. For external and internal turning tasks, selecting the appropriate chipformer and cutting data will optimise cycle times and tool life without the need for specialised fixtures.

Consistent productivity and dependable supply chain

Using an ISO-standard, coated carbide insert from a recognised manufacturer reduces process variance and supports predictable throughput across production runs. The combination of standard dimensions and a resilient grade minimises setup errors and assists with rapid recovery after tool indexing. For manufacturers seeking production reliability, the insert’s design and material characteristics contribute to lower scrap rates and steadier machining performance. If a specific holder or machining scenario requires verification, Metav Werkzeuge can provide application-focused guidance based on shop-floor conditions.

FAQ

What materials is this insert suited for?
The EPGT040101 SH7025 turning insert by Tungaloy is a coated carbide grade designed for versatile turning; the SH7025 grade is chosen to provide edge stability across a broad range of machining conditions, making it suitable when tool robustness is required.

How does the 0.1 mm corner radius affect the turning result?
A 0.1 mm corner radius on the EPGT040101 SH7025 insert improves finish in fine turning operations and reduces the risk of profile chatter, while still allowing for precise contouring where smaller radii are required.

Is the insert compatible with different holder types?
Compatibility depends on holder geometry, clearance angle and size; the ISO form and 1.59 mm thickness of the EPGT040101 SH7025 ensure it fits standard ISO holders of size 04 when form, fastening method and tolerance class match.

What is the benefit of the cylindrical hole with countersink?
The cylindrical hole with 40°–60° countersink ensures accurate axial positioning and secure clamping of the EPGT040101 SH7025 insert, enhancing repeatability and reducing the likelihood of insert movement under cutting forces.

How should the chipbreaker be selected for specific turning tasks?
Choose the chipbreaker and SH7025 grade according to workpiece material, cut depth and machine stability; the single-sided chipbreaker on this insert promotes controlled chip formation for many turning operations, but optimisation of feeds and speeds is recommended for best results.
