EPGT 040104 SH725 Wendeplatten - Tungaloy

Take advantage of the combination of an ISO-standard rhombic geometry, a coated carbide grade SH725 and a compact 0.4 mm corner radius for consistent results in general turning applications; order the insert directly via Metav Werkzeuge or ask the consultants for assistance.

EPGT 040104 SH725 turning insert — Tungaloy, coated carbide, rhombic 04, with hole

EPGT 040104 SH725 is a compact ISO-standard turning insert designed for external and internal turning, offering a tough, edge-stable grade for varied engagement conditions

• ISO‑compliant rhombic insert 04 size
• Coated carbide grade SH725
• One-sided chipbreaker for stable chips
• Cylindrical hole with countersink 40°–60°

Consistent cutting performance for mixed turning tasks

The EPGT040104 insert combines a coated carbide substrate with the SH725 grade to deliver a stable cutting edge under intermittent or varying cutting conditions. Its design supports both external and internal turning operations and is particularly suited to smaller tool assemblies where engagement depth changes. The coated surface improves wear resistance, while the robust grade reduces chipping risk during interrupted cuts, helping maintain dimensional accuracy and predictable process windows.

Simple integration into ISO tool systems

Compatibility is determined by form, relief, tolerance class, fastening, size and thickness; the rhombic 04 size and 75° included angle ensure compatibility with common ISO holders. The insert features a cylindrical hole with a single‑sided countersink (40°–60°) for secure clamping and repeatable seating. The 11° relief and 1.59 mm plate thickness make the insert suitable for compact toolholders, while the 0.4 mm corner radius balances strength and finishing capability. These attributes simplify holder selection and reduce set-up time.

Better chip control and longer productive runs

A one‑sided chipbreaker gives controlled chip formation for a range of materials and cutting modes; this chip control reduces the need for frequent interventions and supports steady cycle times. The combination of geometry and the SH725 cutting grade contributes to extended tool life, particularly when machining with small‑scale tooling or when stability varies. Selecting the appropriate chipbreaker and matching the insert grade to the workpiece material supports efficient material removal and a reliable surface finish.

FAQ

What holders are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening and size; the rhombic 04 format and the 75° included angle of the insert align with common ISO turning holders designed for EPGT‑style plates.

Which materials suit the SH725 grade?
The SH725 coated grade is formulated for tough, edge‑stable performance and is suitable where varying engagement or smaller tools are used; it performs well across a broad range of engineering materials when the chipbreaker and cutting data are matched.

How does the chipbreaker affect machining?
The one‑sided chipbreaker provides predictable chip formation and evacuation, improving machining stability and reducing the risk of chip entanglement in both external and internal turning operations.

Is the insert repeatable after re‑clamping?
The cylindrical hole and single‑side countersink ensure consistent seating and repeatability when re‑clamped in an appropriate ISO‑compatible holder.
