EPGT 040104 GH110 Tungaloy indexable turning insert — for turning

A EPGT040104 GH110 insert engineered for ISO‑standard external and internal turning, offering a rhombic 04 form with 11° clearance for predictable chip formation and secure clamping.

• ISO‑standard rhombic insert 04
• GH110 grade for wear resistance
• One‑sided chipbreaker with through hole
• 11° clearance, 0.4 mm corner radius

Reliable fit and predictable integration for production workflows

The insert is an ISO‑standard indexable turning insert, designed so that compatibility with the toolholder is governed by form, clearance, tolerance class, fixing method, size and thickness. This clear separation of interface parameters simplifies procurement and replacement: when the holder matches these parameters, the insert seats precisely, enabling repeatable cutting performance and reducing setup time. For shops requiring consistent changeover, the standardised geometry supports rapid tool exchanges and predictable process control.

Material grade and cutting performance that extend tool life

Equipped with the GH110 Tungaloy carbide grade, the cutting edge combines enhanced wear resistance with sufficient toughness to withstand intermittent loads. The result is a longer effective life of the cutting edge and a steadier surface finish over extended production runs. The carbide substrate and the chosen grade help maintain edge stability in mixed turning tasks, so fewer interruptions for insert changes are needed and part quality remains reproducible.

Geometry that balances surface quality and chip control

The rhombic 04 shape together with an 11° clearance and a one‑sided chipbreaker delivers reliable chip formation for many turning tasks. The 0.4 mm corner radius provides a compromise between finishing capability and robustness: a small radius improves surface finish while still offering sufficient edge strength for semi‑finishing cuts. The insert thickness of 1.59 mm contributes to negative rake stiffness and supports stable cutting under varying radial depths, which benefits both conventional lathes and CNC turning centres.

Practical applications and process advantages for machine shops

Intended for external and internal turning, this indexable insert is suitable for general production and jobbing environments that require predictable results and good edge life. By choosing the appropriate chipbreaker and taking the GH110 characteristics into account, machining efficiency and process security can be improved. For operations seeking measurable productivity gains, the stable cutting edge and standardised form support higher machine uptime and consistent component quality.

FAQ

What operations is this insert intended for?
The EPGT040104 GH110 insert is intended for turning operations, including both external and internal turning tasks.

How is compatibility with a toolholder ensured?
Compatibility is determined by form, clearance, tolerance class, fixing method, size and thickness; the EPGT040104 requires a holder that matches these parameters for a secure fit.

What is the corner radius and how does it affect finish?
This insert has a 0.4 mm corner radius, which supports improved surface finish while maintaining sufficient edge strength for semi‑finishing cuts.

Does the insert include a hole and what is its style?
Yes — the insert features a cylindrical hole with a one‑side countersink (40°–60°) to accommodate standard clamping and secure fastening.

Which carbide grade is used and what are its benefits?
The GH110 Tungaloy grade provides a balance of wear resistance and toughness, supporting consistent edge life and stable cutting performance across varied turning conditions.
