EPGT040104 SH730 ISO turning insert by Tungaloy — rhombic, 11° clearance, with hole

The EPGT040104 SH730 is an ISO-compliant rhombic indexable turning insert designed for external and internal turning applications, optimised for small tools and varying engagement conditions.

• ISO-compliant rhombic insert, size 04
• Coated carbide grade SH730 for stable edges
• 11° clearance angle for versatile turning
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for mixed cutting conditions

The coated carbide SH730 grade delivers a tough, edge-stable substrate that maintains cutting integrity even under fluctuating engagement and smaller tool geometries. The coating and substrate combination reduces premature edge breakdown and supports stable chip formation, which in turn extends effective tool life and reduces unscheduled insert changes. For machining operations where repeatable surface quality and predictable tool behaviour are required, this insert provides a measurable improvement in process stability.

Faster set-up and secure clamping for productive turning

As an ISO-compliant insert, compatibility with a wide range of holders is determined by geometry, clearance angle, tolerance class, fastening and thickness — factors that simplify tool selection and reduce set-up time on the shop floor. The cylindrical hole with single-sided countersink (40°–60°) enables secure, repeatable clamping and straightforward replacement, while the rhombic shape gives access to multiple effective cutting edges. The resulting reduction in machine downtime supports higher throughput and improved process reliability.

Clear specifications that support precise application planning

Key dimensions and geometry are designed to support predictable performance: a 0.4 mm nose radius, a plate thickness of 1.59 mm, and a 11° clearance angle together define the cutting footprint and rigidity. The single-sided chipbreaker aids evacuation and is most effective when selected to match workpiece material and cutting parameters. The ISO designation and standardised size facilitate stock management and interchangeability across tool systems, allowing production planners to rely on consistent insert data when programming and setting up turning operations.

FAQ

What cutting tasks is this insert intended for?
The EPGT040104 SH730 indexable insert by Tungaloy is intended for external and internal turning, especially where small-tool geometries or changing engagement conditions demand a tough, edge-stable coated carbide.

How is the insert mounted in a holder?
Mounting uses the cylindrical hole with a single-sided countersink (40°–60°); compatibility with the holder depends on form, clearance angle, tolerance class, fastening, size and thickness — details reflected in the EPGT040104 SH730 data sheet (SKU 6862197-Tungaloy).

Which geometric values should be considered when planning a cut?
Important values include the 0.4 mm nose radius, 1.59 mm plate thickness, 11° clearance angle and the rhombic plate shape; these determine cutting footprint, stiffness and recommended cutting parameters for the EPGT insert.

Is this an ISO-standardised insert?
Yes — the insert is part of the ISO turning insert series and follows standardised dimensions and designations to ensure interchangeability across compliant holders.

What are the main advantages of the SH730 grade?
The SH730 coated carbide grade is formulated for stable cutting edges and reliable chip control under variable engagement; it is particularly suitable for smaller tools and situations where consistent edge life is required.
