EPGT 040101 SH730 — Tungaloy ISO turning insert, rhombic 04, coated carbide

The EPGT 040101 SH730 is a rhombic ISO turning insert designed for external and internal turning, offering a robust option where small tools or variable engagement demand reliable edge stability.

• Coated carbide grade SH730
• Rhombic 04 geometry, compact profile
• 11° relief angle for stable cutting
• Cylindrical hole with 40°–60° countersink

Reliable edge stability for short-cycle turning

The combination of the SH730 composition and a coated carbide substrate provides a balance of toughness and wear resistance, making the insert particularly effective in applications with changing engagement or interrupted cuts. This edge-stable grade was developed to reduce edge chipping and maintain consistent cutting performance, which in turn supports more predictable machining cycles and lower scrap rates. The result is improved process reliability for repetitive external and internal turning tasks.

ISO conformity and simple system integration

Manufactured to ISO dimensions, compatibility with the chosen holder depends on geometry, 11° relief angle, tolerance class, clamping method, size and 1.59 mm thickness. The insert forms part of a complete system that includes an ISO insert seat, a matching external holder or boring bar, a shim/clamp set and replacement screws. Specifying the correct holder and clamping hardware ensures secure seating and repeatable tool life, helping to preserve surface finish and dimensional accuracy during production runs.

Practical machining benefits and chip control

The compact rhombic 04 shape and one-sided chipbreaker deliver effective chip control for many turning operations while the small 0.1 mm radius helps to balance corner strength with fine edge definition for improved surface quality. The cylindrical hole with a single-side countersink (40°–60°) provides straightforward clamping and reliable location in the pocket, reducing the risk of insert movement under load. These characteristics support steady material removal rates without unnecessary vibration or premature wear.

Guidance for selecting the right insert configuration

Choose the chipbreaker and grade according to workpiece material, feed and depth of cut, and the rigidity of the tool assembly; the SH730 grade is recommended for situations requiring a tough, chip-resistant edge, especially in small-tool applications or variable engagement. If further specification data or cutting-parameter recommendations are required, the technical team can offer application-focused guidance to align insert choice with production goals and machine capability.
