EPGT 040101 SH725 — Rhomboid ISO turning insert, coated carbide, Tungaloy

The EPGT040101 SH725 is an ISO‑standard rhomboid indexable insert designed for external and internal turning, offering a robust 75° cutting geometry and a single‑sided chipbreaker for controlled chip formation.

• ISO‑standard rhomboid insert
• Coated carbide grade SH725
• 75° cutting geometry for robustness
• 0.1 mm nose radius for fine finishing

High productivity through a tough, edge‑stable grade

The SH725 coated carbide grade is formulated for edge stability and reliable wear behaviour during turning operations, especially where engagement conditions vary. As a result, process security is improved and tool changes are less frequent, which supports higher machine utilisation. The combination of a coated carbide SH725 grade with an ISO‑conform insert geometry enables reproducible results across batches and shortens setup verification time, delivering tangible gains in production efficiency.

Precise geometry that improves surface quality and repeatability

A small 0.1 mm nose radius and a 75° cutting angle produce a balance between fine surface finish and cutting edge robustness. The 11° relief angle reduces rubbing on the flank while maintaining contact stability, and the 1.59 mm plate thickness contributes to stiffness in thin‑walled or intricate holders. Together these geometric parameters reduce vibration and chatter, which translates directly into improved surface finish and tighter dimensional repeatability for turned profiles.

Simple integration in ISO tool systems and secure clamping

Compatibility with the clamping system is determined by form, relief angle, tolerance class, fastening style, size and thickness. The insert features a cylindrical hole + single‑side countersink (40°–60°) that ensures accurate seating and secure torque transmission when combined with the appropriate holder, shim and clamping set. Using standard ISO‑type inserts in matched holders shortens tool preparation and supports predictable changeovers, making the component suitable for mixed‑batch manufacturing and flexible production cells.

Reliable chip control and suitability for variable cutting conditions

The single‑sided chipbreaker design assists controlled chip formation under a range of feeds and depths of cut, reducing the risk of long curled chips that can affect process safety. The SH725 grade is described as a tough grade engineered for stable cutting edges, which is particularly beneficial for smaller tooling or operations where engagement varies. This combination provides a dependable balance between wear resistance and fracture toughness, helping maintain cycle times and lowering the frequency of unexpected interventions.

FAQ

What is the primary application for this insert?
The EPGT040101 SH725 Tungaloy insert is intended for external and internal turning operations, where stable edge behaviour and reproducible chip control are required.

How is compatibility with a toolholder determined?
Compatibility depends on form, relief angle (11°), tolerance class, fastening method, size (04) and thickness (1.59 mm); adherence to the ISO standard simplifies selection of a matching holder.

What does the SH725 designation indicate?
SH725 denotes a coated carbide grade formulated for toughness and cutting‑edge stability, suitable for smaller tooling and changing engagement conditions.

How does the 0.1 mm nose radius affect the turned surface?
A 0.1 mm nose radius produces finer surface finish and more accurate contouring while keeping the cutting edge robust enough for general finishing and light profiling tasks.

Why is the hole style relevant for clamping?
The cylindrical hole with a single‑side countersink (40°–60°) ensures precise seating and reliable clamping torque transmission, reducing the risk of insert movement during heavy cuts.
