EPGT 040101 SH725 EPGT turning insert (ISO 040101) by Tungaloy — coated carbide, 11° relief

The EPGT040101 SH725 is an ISO‑form rhombic turning insert designed for external and internal turning, featuring a single‑sided chipbreaker and a cylindrical mounting hole with a 40°–60° countersink.

• ISO rhombic insert, size 04
• Coated carbide grade SH725
• 11° relief angle for stable cutting
• Cylindrical hole with 40°–60° countersink

Reliable cutting performance with a stable grade

The coated carbide grade SH725 is formulated for edge stability and dependable wear behaviour during turning, making it especially suitable for operations with varying engagement or for smaller tooling systems. Thanks to the coated carbide construction, the insert maintains cutting integrity under intermittent cuts and light to moderate machining forces. This results in fewer indexings, consistent component dimensions and reliable process repeatability, helping to reduce downtime and tool handling.

Clear mounting criteria for secure clamping

The insert conforms to the ISO designation EPGT040101, which streamlines compatibility checks with external holders and boring bars. Compatibility depends on form, 11° relief, tolerance class, clamping method, size and thickness, so matching the ISO rhombic geometry and the 1.59 mm thickness ensures a secure fit. The cylindrical hole with a single‑side countersink (40°–60°) provides positive seating and reproducible clamping when used with the appropriate shim and screw set, improving concentricity and repeatable positioning in production setups.

Geometry tuned for surface and edge control

The 0.1 mm corner radius on this insert balances edge strength with the ability to achieve fine surface finishes on turned parts. Combined with the single‑sided chipbreaker, the geometry encourages predictable chip formation and evacuation for many turning operations. Selecting the correct chipbreaker and grade relative to the machining conditions optimises chip flow and cutting forces; this in turn supports stable cutting, consistent surface quality and longer tool life, which are central to efficient production workflows.

System approach and practical use

This ISO turning insert is intended to be used as part of a system: the insert itself paired with a suitable external holder or boring bar, plus shim/clamp sets and replacement screws where required. The model series is designed so that the user can choose the chipbreaker and grade best suited to the workpiece and process stability. For routine workshop implementation, the combination of the EPGT040101 geometry and the SH725 coating simplifies inventory management while offering flexibility across a range of turning tasks.

FAQ

What holders are compatible with this insert? The EPGT040101 geometry requires holders that accept ISO rhombic inserts of size 04 with 11° relief; ensure the clamp and tolerance class match the EPGT040101 SH725 for correct seating.

Which machining tasks is the SH725 grade intended for? The SH725 coated carbide grade is intended for turning operations where edge stability is required, particularly useful for smaller tools and changing engagement conditions.

How does the corner radius affect the turned surface? A 0.1 mm corner radius gives a compromise between edge strength and surface finish; it supports controlled cutting forces and helps achieve consistent surface quality on turned components.

What is the purpose of the countersunk hole design? The cylindrical hole with a 40°–60° single‑side countersink provides positive seating and reproducible clamping when used with the correct shim and screw set, improving repeatability in production.
