EPGT 040104 SH725 — Indexable turning insert, rhombic, 75° geometry, Tungaloy

The EPGT040104 SH725 is an ISO‑standard rhombic indexable insert for external and internal turning, engineered for stable cutting under variable engagement conditions and designed for use with compatible ISO holders.

• Coated carbide grade SH725 for durable cutting edges
• Rhombic 75° form for versatile external and internal turning
• 0.4 mm corner radius for controlled chip formation
• Cylindrical hole with countersink for reliable clamping

High‑performance grade for variable cutting conditions

The insert is manufactured from coated carbide in the SH725 grade, a formulation focused on toughness and edge stability. This makes the component particularly suitable for small tools and operations where engagement conditions change frequently. The 0.4 mm corner radius moderates cutting forces and helps to avoid premature edge chipping, while the applied coating extends tool life by improving wear resistance. For production environments seeking a balance of life and reliability, this grade supports steady cycle times and reduced tool change frequency.

ISO compatibility and secure mounting for repeatable results

Designed as an ISO indexable insert, the component fits typical ISO‑compliant holders when the holder’s form, clearance angle (11°), tolerance class, fixing and size match the insert specification. The rhombic plate form and 75° approach angle give flexibility for both external and internal turning tasks. The cylindrical hole with one‑sided countersink (40°–60°) ensures secure clamping and consistent seat location, which reduces assembly variability and supports repeatable geometry in serial production. Mismatched holder geometry or incorrect tolerance classes can lead to instability; therefore, correct pairing of insert and holder is essential for safe, efficient machining.

Application guidance and productivity benefits

This insert features a single‑sided chipbreaker and a plate thickness of 1.59 mm, enabling controlled chip formation in many cutting scenarios. Typical use cases include finishing and medium‑duty roughing in turning operations; selection of the most suitable chipbreaker and the SH725 grade should follow the workpiece material and machining strategy. The robust cutting edge behaviour contributes to fewer unscheduled stops and consistent surface quality. For complex production needs, technical drawings and compatibility checks can be provided to ensure the insert integrates cleanly into existing tool systems.

FAQ

What is the primary application for this insert?
The EPGT 040104 SH725 insert is intended for turning operations, suitable for both external and internal turning where a rhombic, 75° geometry is beneficial.

Which workpiece materials are appropriate for this grade?
The SH725 grade provides tough, edge‑stable performance; the insert can be used across a broad range of materials but the chipbreaker and specific cutting data should be selected according to the workpiece material and machining type.

How is the insert clamped in the toolholder?
Clamping is achieved via the cylindrical hole with a one‑sided countersink (40°–60°); secure and repeatable seating requires a matching ISO‑compliant holder and correct tolerance class.

What effect does the 0.4 mm corner radius have?
A 0.4 mm corner radius reduces local stress on the cutting edge, improves edge strength and contributes to controlled chip formation and surface finish in finishing and medium‑cutting operations.
