EPGT040102 UX30 Tungaloy indexable turning insert — uncoated carbide, rhombic 04, 11° clearance

The EPGT040102 is an ISO-standard rhombic indexable insert designed for precision external and internal turning applications where low cutting forces and controlled chip formation are required

• ISO-standard rhombic 04 geometry
• Sharp-edge UX30 grade for low cutting forces
• Cylindrical hole with single-sided countersink
• 0.2 mm corner radius for improved surface finish

High-efficiency turning with a sharp UX30 grade

This insert combines a sharp cutting edge with an uncoated carbide substrate to reduce cutting forces and promote predictable chip breakage. The UX30 grade is engineered for operations where minimised cutting resistance and consistent chip formation make the process more productive; because the grade is uncoated, it performs well where abrasive wear is moderate and edge integrity is paramount. The result is improved cycle times on light to medium turning tasks and fewer interruptions for rework.

Precise mounting and compatibility for stable machining

Designed to ISO standards, the geometry, 11° clearance angle, tolerance class and thickness must match the chosen holder to ensure clamping security and repeatable positioning. The rhombic 04 form and the cylindrical hole with single-sided countersink (40°–60°) facilitate secure fastening and straightforward indexation, so changeovers are efficient and tool life is reproducible. Because correct holder pairing determines performance, compatibility is verified by form, free angle, fastening type, size and thickness.

Chip control and surface quality in demanding operations

A one-sided chipbreaker combined with the 0.2 mm corner radius helps to shape chips and reduce the risk of built-up edge, contributing to a finer surface finish on turned components. The 1.59 mm plate thickness and the rhombic geometry support controlled engagement in narrow depths of cut, making the insert suitable for finishing passes or where tight tolerances are required. The design therefore balances chip control and dimensional stability for consistent part quality.

Practical benefits for production-oriented workshops

The insert is part of an ISO-series system concept that pairs with matched holders, shim sets and clamping screws, enabling quick replacement and straightforward inventory management. Its uncoated carbide body provides a stable cutting edge that is resilient in face of intermittent cutting conditions and small interruptions. For machinists and production planners this translates into predictable tool behaviour and easier process planning, reducing setup time and increasing shop-floor uptime.

FAQ

What materials is this insert suitable for?
The EPGT040102 UX30 insert is intended for general turning tasks; the UX30 uncoated carbide grade offers good chip formation and low cutting forces for a broad range of steels and non-hard materials.

How should the insert be mounted for best results?
Mounting must match the ISO holder form, clearance angle and thickness; the rhombic geometry and cylindrical hole with countersink require a compatible clamping seat and fastening screw for secure positioning.

Can this insert be used for finishing passes?
Yes, the 0.2 mm corner radius and slim 1.59 mm thickness make the insert well suited to finishing and light material removal where surface quality is important.

What is the benefit of the uncoated carbide UX30 grade?
The UX30 grade provides a sharp, stable cutting edge that reduces cutting forces and promotes consistent chip formation, which is advantageous in applications prioritising edge integrity over high-temperature resistance.

Is the insert compatible with standard ISO toolholders?
The plate conforms to ISO dimensions; compatibility is determined by matching the insert form, free angle, tolerance and thickness with the toolholder specifications.
