EPGT040102 SH725 indexable insert for turning — Tungaloy

EPGT040102 SH725 Tungaloy indexable insert for external and internal turning with rhombic ISO 04 form, single-sided chipbreaker and a cylindrical hole with one-sided countersink

• Coated carbide grade SH725
• Rhombic ISO 04 geometry
• 0.2 mm corner radius for fine finishing
• Cylindrical hole with 40°–60° countersink

High-performance grade for reliable turning results

The EPGT040102 SH725 is an ISO-standard indexable insert manufactured for robust turning tasks where changing engagement conditions occur. The coated carbide construction and specific SH725 grade provide a balance between toughness and edge stability, making the insert particularly suitable for small tools and variable cuts. The coating enhances wear resistance while the base carbide ensures shock tolerance, which together extend tool life and reduce interruption in production.

Precise geometry that supports surface quality

The rhombic ISO 04 form combined with a 0.2 mm corner radius and 1.59 mm thickness delivers predictable contact geometry and surface finish. The specified 11° clearance (relief angle) controls cutting forces and helps avoid rubbing on the flank, while the 75° included angle governs approach and chipflow direction. These geometric parameters translate into fewer vibrations and an improved surface on the workpiece, which is especially beneficial when performing finishing passes on components machined from a range of steels and alloys.

Design features that simplify clamping and chip control

A cylindrical hole with a single-side countersink (40°–60°) ensures secure locating and repeatable seating in compatible holders. The one-sided chipbreaker promotes controlled chip segmentation for many turning scenarios; combined with the insert’s coated substrate, chip formation stays stable across interrupted cuts and varying depths of cut. The outcome is reduced risk of built-up edge and more consistent cycle times during batch production.

Selection advice and system compatibility

Compatibility with a chosen holder depends on the insert’s shape, relief angle, tolerance class, fastening method, size and thickness. Select the correct clamp style and screw set to match the ISO geometry and the insert’s hole/countersink arrangement; this prevents misalignment and ensures the SH725 grade performs as intended. For applications requiring repeatable results and easy index changes, pair the insert with holders designed for ISO rhombic 04 inserts and verify seating with the recommended torque and backing pads.

FAQ

What materials is this insert suitable for?
The answer depends on the selected grade and machining parameters; the SH725-coated carbide insert is designed for a broad range of turning tasks and offers good edge stability on many steels and alloys.

How does the 0.2 mm corner radius affect finishing?
A 0.2 mm corner radius produces a finer edge transition and helps achieve improved surface quality during finishing passes compared with larger radii.

Is the insert compatible with standard ISO rhombic 04 holders?
Yes, the insert follows ISO rhombic 04 geometry; compatibility requires matching holder design, fastening method and tolerance class.

What is the purpose of the single-sided chipbreaker?
The single-sided chipbreaker promotes predictable chip segmentation for turning operations, aiding chip evacuation and reducing the risk of tangling on the workpiece.

How should the insert be clamped and indexed?
Clamp the insert using a holder compatible with the cylindrical hole and countersink geometry, ensure correct seating and apply the recommended clamping torque to maintain repeatable positioning.
