EPGT 040100 SH725 — Tungaloy turning insert, rhombic 04, 11° relief

The EPGT040100 SH725 insert is an ISO rhombic turning insert intended for stable external and internal turning, optimised for small tools and varying engagement conditions.

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

Consistent cutting performance for everyday turning

The rhombic 04 geometry combined with the coated carbide grade provides a dependable solution for a wide range of turning tasks. Designed as an ISO‑standard indexable insert, this component delivers repeatable seating in standard holders and enables predictable cutting behaviour. The SH725 grade is formulated for toughness and edge stability, which reduces the risk of premature chipping when machining interrupted cuts or when using smaller diameter tools. The result is less downtime and a steadier production flow.

Improved edge life and chip control where it matters

A single‑sided chipbreaker tailored to the geometry facilitates controlled chip formation and evacuation during both external and internal operations. The combination of a tough substrate and a functional coating promotes wear resistance and sustained sharpness at the cutting edge, extending tool life and reducing insert changes. For shops seeking efficiency, the better edge retention of this grade translates into fewer machine stops and lower overall tooling consumption.

Designed for secure clamping and broad compatibility

Compatibility with holders is determined by form, relief angle, tolerance class, fixing, size and thickness. The 11° relief and the rhombic form make the insert suitable for a range of external holders and shank tools; the cylindrical hole with one‑side countersink (40°–60°) ensures secure fastening and simple replacement of screws. A complete working system includes the insert, a matching external holder or shank, a shim/clamping set and replacement screws — all selected to match the geometry and tolerance requirements for safe, repeatable clamping.

Practical guidance for selecting the right grade and geometry

When choosing an insert for turning, select the chipbreaker and grade according to material, machining type and stability of the setup. The SH725 grade is recommended for applications that demand toughness and reliable edge integrity, especially when conditions vary or when smaller tooling is used. With a plate thickness of 1.59 mm and a compact rhombic outline, this geometry supports fine finishing as well as general‑purpose turning tasks. Where high process stability and consistent surface quality matter, this insert offers a balanced compromise between economy and performance.
