EPGT 040104 SH730 — Turning indexable insert by Tungaloy

EPGT040104 SH730 is an ISO rhombic turning insert designed for reliable external and internal turning where edge stability and repeatable clamping are required.

*SH730 coated carbide for tough cutting conditions
*Rhombic ISO insert, 75° cutting edge angle
*0.4 mm corner radius for versatile finishing
*Cylindrical hole with single-sided countersink

Consistent edge stability for variable engagement

The SH730 grade is a coated carbide developed for stable cutting-edge performance, particularly suited to smaller tooling and changing engagement conditions. This provides a clear production advantage: consistent chip formation under varying depths of cut leads to fewer interruptions and longer effective tool life. Specified as an ISO rhombic insert, the geometry supports predictable cutting behaviour and aids toolpath planning in turning operations.

Secure clamping and process repeatability

The insert’s ISO conformity and precise geometry ensure compatibility with matched holders when form, clearance, tolerance class, clamping method, size and thickness are observed. The cylindrical hole with one-sided countersink (40°–60°) and a plate thickness of 1.59 mm contribute to a tight mechanical fit, reducing vibration and improving repeatability. As a result, set-up times are reduced and process stability is increased in batch production.

Geometry tuned for finishing and general turning

A 75° cutting edge angle combined with a 0.4 mm corner radius makes this insert well suited to both light finishing passes and general turning tasks where surface quality matters. The 11° clearance helps prevent rubbing while preserving edge strength. The one-sided chipbreaker assists chip control in many operations, improving swarf evacuation and reducing the risk of built-up edge during continuous cuts.

Practical system integration and selection advice

The component is part of an ISO insert system including the matching external holder or boring bar, suitable shim or clamping kit and replacement screws. Selecting the correct chipbreaker and the SH730 grade for the workpiece and machining strategy will maximise productivity and consistency. For applications with changing engagement or smaller tools, the insert’s combination of grade and geometry delivers reliable performance with straightforward tool management.

FAQ

What applications suit this insert best?
The EPGT040104 SH730 Tungaloy turning insert is intended for external and internal turning where stable cutting edges and predictable chip control are required, particularly with smaller tools or variable engagement.

How does the SH730 grade affect tool life?
The SH730 coated carbide grade offers enhanced edge stability under changing cutting conditions; this typically results in more consistent wear behaviour for the EPGT040104 SH730 insert and longer productive intervals between indexings.

Which holder characteristics are important for compatibility?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the ISO rhombic form and 1.59 mm plate thickness of the EPGT040104 SH730 insert should be matched to the holder specifications.

Does the insert provide good chip control?
Yes. The one-sided chipbreaker combined with the insert geometry supports controlled chip formation for many turning operations when using the EPGT040104 SH730 insert.

What does the hole style mean for mounting?
The cylindrical hole with a single-sided countersink (40°–60°) on the EPGT040104 SH730 insert ensures reliable clamping and alignment in compatible toolholders, improving mechanical stability.
