EPGT 040101 SH730 Turning insert by Tungaloy — 75° rhombic 04, coated carbide

EPGT 040101 SH730 is an ISO-format turning indexable insert designed for precision external and internal turning in standard holder systems

• ISO rhombic insert EPGT 040101 SH730
• 75° geometry for robust external turning
• Coated carbide grade SH730 for stable edge
• Cylindrical hole with 40°–60° one-sided countersink

Stable cutting edges for mixed entry conditions

The coated carbide grade SH730 is formulated for edge toughness and consistent performance under varying engagement conditions. As a consequence, insert life is extended where feed or depth of cut varies and where intermittent cuts occur. The result is fewer tool changes and improved process reliability. The coating supports heat resistance and wear control while the substrate delivers the toughness needed for small tools and unstable cut conditions.

Geometry that balances strength and finish

A 75° cutting geometry combined with the rhombic 04 form gives a robust edge line suited to general and heavy-facing cuts while still permitting accessible approach angles for external operations. The 0.1 mm corner radius provides a compromise between strength and surface finish, enabling consistent part tolerances. The 11° clearance reduces flank contact and heat generation, helping to maintain dimensional accuracy and surface quality with lower risk of rubbing.

Secure clamping and ISO compatibility for predictable results

Clamping is facilitated by a cylindrical hole with a one-sided countersink (40°–60°) that ensures positive seating in common ISO-compatible holders. The insert thickness of 1.59 mm and single-sided chipbreaker design contribute to stable chip control and mechanical security under load. Compatibility with a holder is determined by matching form, clearance angle, tolerance class, clamping method, size and thickness, so selection within the ISO system yields reproducible cutting conditions and simplifies tool inventory.

FAQ

What operations is this insert intended for?
The insert is intended for external and internal turning operations; the EPGT 040101 SH730 insert suits general turning tasks within ISO holder systems.

What material and grade is used for the cutting substrate and coating?
This insert is made from coated carbide in the SH730 grade, designed for edge stability and good wear resistance under mixed cutting conditions.

How is the insert secured in the toolholder?
The insert uses a cylindrical hole with a one-sided countersink (40°–60°) to ensure reliable seating and clamping in compatible ISO toolholders.

Which geometry features influence surface finish and strength?
The 75° geometry, 0.1 mm corner radius and 11° clearance combine to balance cutting strength and surface quality, enabling controlled finishing while maintaining edge robustness.

What does the ISO code 040101 indicate?
The ISO code reflects the standardised geometry and size within the ISO system: the designation 040101 corresponds to the rhombic 04 form and the specified geometric parameters used for matching holders and tool systems.
