EPGT 040102 GH110 – Tungaloy indexable turning insert for turning (rhombic, 75°)

EPGT 040102 GH110 is a rhombic ISO indexable insert designed for general turning and finishing operations, offering a balance of wear resistance and edge stability for demanding production environments.

• ISO‑compliant rhombic insert
• Tungaloy GH110 grade for durability
• 0.2 mm corner radius for fine profile control
• Single‑sided chipbreaker with hole

Consistent cutting performance for production turning

The insert is engineered to deliver reproducible results across batch and single‑piece production. Built on a cemented carbide substrate and supplied in the GH110 grade from Tungaloy, this turning solution provides a measured compromise between hardness and toughness that reduces edge breakdown and extends tool life. The 75° included angle and 11° relief angle create a robust cutting edge that resists chipping under interrupted or stable cuts, while the single‑sided chipbreaker helps to control chip formation and evacuate swarf more predictably. These characteristics translate into fewer tool changes and a steadier process window on both shopfloor and CNC turning centres.

Geometry and grade explained — why it matters for part quality

The rhombic form with a 0.2 mm corner radius gives a precise contour for delicate external profiles and light finishing passes, keeping dimensional scatter to a minimum. The insert thickness of 1.59 mm and the ISO designation 040102 define the seating and clamping requirements, so selecting the correct holder geometry is essential for consistent cutting conditions. The GH110 grade complements the geometry by offering enhanced wear resistance without sacrificing the necessary edge toughness; in practice this means improved surface finish and longer intervals between re‑grinds. The presence of a cylindrical hole plus a single‑side countersink (40°–60°) ensures secure clamping and correct axial positioning in appropriately designed toolholders.

System compatibility and workshop advantages

This insert is part of a standard ISO turning insert system and will be compatible with holders and boring bars that match the ISO form, relief angle, tolerance class, fastening method, size and thickness. Including the insert in a systematic tooling setup facilitates fast changeovers: simply pair the insert with the matching external holder, shim/clamping kit and spare screws to restore cutting performance quickly. The Tungaloy carbide grade and chipbreaker design support efficient metal removal and consistent surface quality, which reduces downstream finishing effort and improves overall process economy.

FAQ

What applications suit this insert best?
The EPGT040102 GH110 Tungaloy indexable insert is intended for general external and internal turning tasks where a rhombic insert and a 75° included angle are advantageous for profile work and finishing.

How does the GH110 grade affect performance?
The GH110 grade supplied by Tungaloy provides a balance of wear resistance and edge toughness, meaning the EPGT040102 delivers longer life in abrasive conditions while maintaining stable cutting edges.

Is this insert compatible with standard ISO holders?
Yes, the insert complies with ISO form and size (040102) and will fit holders that match the form, relief angle, tolerance class, fastening method, size and thickness specified for this type.

What is the benefit of the single‑sided chipbreaker?
The single‑sided chipbreaker on this insert helps control chip flow and breakage, improving swarf evacuation and reducing the risk of chip entanglement in turning operations using the EPGT040102 GH110 insert.

How should the hole and countersink be used when mounting?
The cylindrical hole with a single‑side countersink (40°–60°) ensures precise axial positioning and reliable clamping when the insert is secured in a matching insert seat and clamping kit.
