EPGT040104 SH725 ISO turning insert by Tungaloy — rhombic 04, 11° relief

EPGT040104 SH725 is an ISO‑standard turning insert engineered for external and internal turning with a single‑sided chipbreaker and a cylindrical locating hole

• ISO rhombic insert EPGT040104 in grade SH725
• Coated carbide for stable cutting edge
• Single-sided chipbreaker for controlled chips
• 11° relief angle, 0.4 mm corner radius

Increased process stability for routine turning

The coated‑carbide composition and the SH725 grade deliver a balance between toughness and wear resistance that benefits repeatable turning tasks. With a rhombic 04 footprint and 0.4 mm corner radius, the insert offers predictable engagement and a consistent cutting line, reducing vibration and minimising unexpected tool changes. The result is a more dependable cycle time and reduced scrap rate when machining components where dimensional consistency matters.

Clear mounting and compatibility reduce setup time

Compatibility with a toolholder is defined by form, relief angle, tolerance class, fastening, size and thickness, so the insert integrates into standard ISO turn‑tool systems with no surprises. The cylindrical hole with a single‑side countersink (40°–60°) ensures secure clamping and accurate seating in compatible holders. This predictable interface shortens setup, improves repeatability and simplifies inventory management for workshop toolrooms.

Controlled chip formation for safer turning

The single‑sided chipbreaker is designed to direct and fragment chips for stable evacuation during both external and internal turning. Combined with the coated substrate, this geometry supports continuous cutting under varying engagement conditions, particularly useful on smaller tools or when cutting parameters fluctuate. The engineered chip control assists coolant flow and contributes to safer machining cycles and cleaner lathe environments.

Practical advice on materials and applications

Intended primarily for turning, the insert is suited where a tough, edge‑stable grade is needed — especially when smaller inserts or variable cut depths are used. The combination of coating and grade makes this insert appropriate for a wide range of steels and alloyed materials; selection of the chipbreaker and grade should match the workpiece material and machining stability. Where roughing and finishing alternate on short runs, this insert offers the resilience and edge security to maintain surface quality.
