EPGT 040102 SH730 ISO turning insert for turning — Tungaloy

EPGT040102 SH730 is an ISO rhombic turning insert designed for reliable external and internal turning with a tough, edge-stable coated carbide grade.

• Coated cemented carbide SH730
• Rhombic 04 form, 75° geometry
• 11° clearance, 1.59 mm thickness
• Single-sided chipbreaker with hole

Precision and compatibility for consistent machining

The ISO standard form ensures consistent fitment in holders that match by shape, clearance angle, tolerance class, fastening and thickness, which reduces setup variability and improves repeatability. With an 11° clearance and a 75° cutting geometry, the insert gives a clear definition of the cutting edge orientation and predictable contact conditions. This predictability shortens adjustment time during tool changes and helps maintain process stability across batches. The rhombic 04 plate form and the standardised mounting ensure the insert integrates smoothly into established tool systems, supporting faster changeovers and consistent component quality.

SH730 grade: toughness and edge stability for varied engagement

The SH730 grade is a tough, edge-stable coated cemented carbide developed for turning operations where tool size or engagement conditions vary. The coating and substrate combination is selected to resist chipping and wear during interrupted cuts or fluctuating depths of cut; this translates into longer in-process life and fewer unscheduled tool changes. For applications with smaller tool bodies or changing entry angles, the grade’s toughness maintains a reliable cutting edge, helping to sustain cycle times and reduce scrap rates. In production terms, that means lower tool consumption and a steadier output.

Geometry and chip control for improved surface finish

The insert’s 0.2 mm corner radius and single-sided chipbreaker support controlled chip formation and a balanced cutting load, which contributes to a finer surface finish on external and internal profiles. The plate thickness of 1.59 mm combined with the rhombic geometry provides sufficient support for the cutting edge while allowing access in confined areas. The central cylindrical hole with a one-sided countersink (40°–60°) enhances clamping security in compatible holders and helps to maintain alignment under load. Together, these geometric details aid chip evacuation and reduce the risk of edge damage, supporting consistent part quality.

Practical selection advice for turning applications

Select the chipbreaker and grade to suit the workpiece material, machining strategy and machine stability; a tougher grade such as SH730 is preferable for interrupted cuts or variable engagement, while the chipbreaker choice affects chip flow and surface quality. Compatibility depends on matching the insert by form, clearance angle, tolerance and thickness to the chosen holder and clamping system. When these parameters are aligned, the result is a robust turning solution that balances productivity with predictable component quality and economical tool life.

FAQ

What is the primary application of this insert?
The EPGT040102 SH730 insert is intended for turning, covering both external and internal operations where a rhombic insert form and a tough, edge-stable grade are advantageous.

How does one ensure the insert fits the holder correctly?
Compatibility is achieved by matching the insert’s form, 11° clearance, tolerance class, fastening method, size and 1.59 mm thickness to the holder specification; the cylindrical hole and countersink help secure clamping.

What machining conditions suit the SH730 grade best?
The SH730 grade is designed for varied engagement and smaller tool setups; its toughness and coating resist edge chipping during interrupted cuts and unstable entry conditions.

Which geometry features aid chip control and surface finish?
The rhombic 04 form, 0.2 mm corner radius and single-sided chipbreaker promote controlled chip formation and contribute to an improved surface finish on turned parts.
