EPGT 040102 SH730 indexable insert for turning — rhombic 04 | Tungaloy

The EPGT 040102 SH730 is an ISO‑standard rhombic indexable insert for external and internal turning, designed for stable cutting under varying engagement conditions and compact tool assemblies.

• ISO‑standard rhombic insert 04
• Coated carbide grade SH730
• 0.2 mm corner radius for fine finishing
• Cylindrical hole with countersink 40°–60°

Reliable machining performance with a robust coated carbide grade

The insert is manufactured from coated carbide in the SH730 grade, a formulation optimised for toughness and a stable cutting edge. This material pairing reduces premature chipping during interrupted cuts and when using smaller toolholders, delivering consistent results in short‑batch and mixed‑operation environments. The hardened coating supports wear resistance, enabling predictable edge behaviour and longer in‑process life, which in turn lowers tooling costs per component.

Geometry and dimensions that reduce vibration and improve repeatability

Built to ISO specifications, the geometry includes a 75° included angle and a 11° relief angle, combined with a 0.2 mm corner radius and a plate thickness of 1.59 mm. These dimensions increase rigidity at the cutting zone and help to dissipate cutting forces evenly, which improves surface finish and dimensional accuracy. The compact form factor supports use in confined setups while maintaining an effective cutting edge for finishing and semi‑finishing operations.

Practical mounting features for fast changeovers and secure clamping

The insert is supplied with a hole, featuring a cylindrical hole and a single‑side countersink (40°–60°), which ensures secure fixing in compatible clamping systems. The rhombic 04 shape and single‑sided chipbreaker facilitate straightforward indexing and reorientation on external holders or boring bars. A complete system typically consists of the ISO insert, the matching external holder or boring bar, a shim/clamp set and replacement screws for immediate interchangeability and minimal downtime.

Grade benefits and application suitability for productive turning

The SH730 grade emphasises toughness and edge stability, making it particularly suitable where engagement conditions vary or when using smaller tool geometries. The combination of a dependable substrate and coating supports a wide range of turning tasks while maintaining consistent performance. When paired with a correctly selected holder and clamping arrangement, this insert contributes to productive machining with less risk of unexpected tool changeovers.

FAQ

Is the insert compatible with standard ISO holders?
Compatibility is determined by the insert form, relief angle, tolerance class, clamping method, size and thickness; the EPGT 040102 SH730 conforms to ISO standards for use with matching holders.

What does the SH730 designation mean for performance?
SH730 denotes a coated carbide grade focused on toughness and a stable cutting edge, suited to turning tasks where variable engagement and small tool geometries are common.

Which dimensions should be checked before ordering?
Check the included angle (75°), relief angle (11°), corner radius (0.2 mm), plate thickness (1.59 mm) and the hole/countersink style to ensure correct fitment.

Can this insert be used for internal turning operations?
Yes, the geometry and single‑sided chipbreaker make it suitable for both external and internal turning applications when paired with an appropriate boring bar or internal holder.

What additional components are required to mount the insert?
A compatible external holder or boring bar, the correct shim/clamp set and replacement screws are required to form the complete clamping system for the insert.
