EPGT 040104 SH730 EPGT ISO turning insert, rhombic 04 — Tungaloy

The EPGT040104 SH730 indexable insert is a rhombic 04 turning grade designed for external and internal turning with an 11° clearance and a 0.4 mm corner radius.

• Coated carbide grade SH730
• Rhombic 04 geometry for versatile turning
• 11° clearance for stable cutting action
• Central hole with cylindrical countersink

Consistent cutting performance under variable conditions

The combination of the SH730 coating and a coated carbide substrate is engineered for reliable, edge-stable performance in turning operations. The grade provides improved toughness for fluctuating engagement and smaller tooling setups, reducing the risk of edge chipping. With a 0.4 mm corner radius the insert balances strength and surface finish, enabling predictable tool life and fewer interruptions in production. This leads to more economical machining and a lower overall cost per component.

Fast, standardised mounting for process reliability

Compatibility with holder systems is defined by geometry, 11° clearance, tolerance class, fastening and plate thickness, which simplifies tool selection and reduces setup time. The rhombic 04 format and central hole with a cylindrical countersink (40°–60°) ensure secure clamping and repeatable positioning in standard ISO holders. As a result, cycle-to-cycle variation is minimised and setup becomes a measurable contributor to process stability rather than a source of scrap.

Broad material coverage and grade advantages

The SH730 grade is intended for tough conditions where cutting-edge stability is required; it is particularly suitable when workpiece materials and cutting forces vary. The coated compound helps manage heat and wear, extending the effective tool life compared with uncoated grades. Selecting this insert supports consistent surface quality during both roughing and finishing passes while offering flexibility across a wide range of steels and alloyed materials.

Practical details that aid inspection and tool management

Key dimensions and form factors make the insert straightforward to inventory and inspect: ISO designation, 1.59 mm thickness, rhombic plate form and clear marking of the 040104 geometry speed up identification on the shop floor. The single-sided chipbreaker assists in predictable chip formation and evacuation in typical turning operations. Clear, verifiable specifications facilitate tool management, help planners compare alternatives quantitatively and support maintenance of machining standards.
