EPGT 040104 GH110 Tungaloy turning insert — rhombic ISO insert, 75°

EPGT040104 GH110 is an ISO-standard rhombic turning insert designed for precision external and internal machining in general turning applications.

• ISO rhombic insert, 75° principal cutting edge
• GH110 grade for wear resistance and toughness
• Cylindrical hole with one-sided countersink
• 0.4 mm corner radius, 1.59 mm thickness

Consistent cutting performance through optimized grade and geometry

The GH110 grade from Tungaloy combines wear resistance and edge toughness to deliver repeatable results in production turning. The rhombic 75° main cutting edge and the 0.4 mm corner radius reduce cutting forces while maintaining a robust edge, which translates into longer service cycles and fewer indexings. This balancing of properties supports stable surface finish and dependable dimensional control when machining shafts, shoulders and profiles. Selecting the correct chipbreaker and holder setup further improves chip evacuation and process reliability.

Precise fit and repeatable clamping for accurate parts

The insert’s ISO-standard geometry ensures compatibility with a wide range of external holders and boring bars; fit is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness. The 1.59 mm thickness and rhombic form provide a compact, rigid contact area that reduces vibration in light to medium-duty turning. A cylindrical hole with one-sided countersink (40°–60°) secures positive clamping and simplifies replacement, while the nominal 11° relief angle aids clearance and reduces rubbing on complex contours. Together, these features make the system easier to set up and maintain, supporting consistent tolerances across batch runs.

Flexible integration across turning tasks and materials

Intended for external and internal turning, the insert accepts a single-sided chipbreaker and is suitable for a range of materials when the correct chip control and cutting data are selected. The carbide substrate and GH110 surface characteristics provide good generality: the grade performs well where a mix of wear resistance and edge stability is required. In practice, the insert is part of a system—indexable insert, matching holder or boring bar, shim/clamp set and replacement screws—which allows rapid adaptation to different batch sizes and component geometries. This flexibility shortens downtime and contributes to a more productive workshop flow.

FAQ

What materials is this insert suitable for?
The EPGT040104 GH110 insert is a carbide indexable insert designed for turning; the GH110 grade provides a balance of wear resistance and toughness suitable for a wide range of steels and mixed material batches when paired with the appropriate chipbreaker.

How does the rhombic 75° geometry affect machining?
A rhombic 75° insert offers a compromise between strength and access: the geometry provides a sturdy cutting edge for general turning while enabling turning of shoulders and mouldings with good surface finish when correctly set up.

What does the cylindrical hole with countersink improve?
The cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping and accurate repeatability in the tool pocket, reducing movement under load and simplifying fast replacement in the clamping system.

Can this insert be used for internal and external turning?
Yes, the insert is intended for both external and internal turning; compatibility with the holder must be checked for form, clearance, tolerance class, fastening, size and thickness to ensure correct seating.

Which components are needed to assemble a working system?
A complete system comprises the indexable insert, a matching outer holder or boring bar, an appropriate underlay/shim and clamp set, plus replacement screws; together they deliver the necessary rigidity and repeatability for consistent production.
