EPGT 040102 SH7025 indexable turning insert by Tungaloy — ISO-standard 75° rhombic insert for external and internal turning

The EPGT 040102 SH7025 is an ISO-standard indexable insert designed for external and internal turning, offering a coated carbide grade optimised for edge stability and variable engagement conditions

• ISO-standard rhombic insert 75° geometry
• SH7025 coated carbide for edge stability
• One-sided chipbreaker, hole with 40°–60° countersink
• 0.2 mm corner radius, 1.59 mm plate thickness

Consistent machining performance through a robust coated carbide grade

The SH7025 coating and the underlying coated carbide substrate are formulated for edge stability under changing cutting conditions, which leads to consistent tool life and reduced unplanned stoppages. In practice, this means the insert sustains a reliable cutting edge during sequence changes and smaller toolholders, helping maintain production flow. The coating reduces adhesion and wear, while the tougher substrate tolerates intermittent chip loads; together these properties give a balance between wear resistance and toughness that suits general-purpose turning tasks.

ISO geometry and clamping design that simplifies toolholder compatibility

The insert’s ISO-standard designation and its 75° rhombic form make selection and documentation straightforward in a toolroom environment. Compatibility with a holder is determined by form, clearance angle, tolerance class, clamping method, size and thickness — details that are standardised so the insert fits compatible external holders and boring bars. The one-sided chipbreaker and the cylindrical hole with 40°–60° countersink support positive clamping and predictable chip control, which helps maintain surface finish and reduces the need for extensive process tuning when switching inserts.

Precise dimensions for repeatable surface finish and toolpath planning

A 0.2 mm corner radius supports finer surface finishes at common finishing feeds, while the 11° clearance angle reduces rubbing and heat buildup at the flank, improving surface integrity and part tolerances. The nominal 1.59 mm plate thickness and the size code (04) ensure mechanical stability in the intended range of bore and external turning operations. By selecting the appropriate feed and depth of cut to match the small corner radius, the result is a predictable balance of edge strength and finished-part quality, especially useful when machining components that demand consistent dimensional accuracy.

Practical advantages for workshop use and process planning

Being an ISO-spec insert, the item integrates easily into existing tool management systems and stock lists, which simplifies procurement and replacement cycles. The insert’s chip control features and robust grade mean fewer insert changes in mixed-production environments, improving overall productivity. For operators assessing inserts for specific materials or hardness ranges, the coated carbide grade offers broad applicability; paired with the correct chipbreaker style and holder rigidity, it supports a wide spectrum of turning tasks from semi-finishing to light finishing.

FAQ

What materials is this insert suitable for?
The EPGT 040102 SH7025 insert is formulated with a coated carbide grade that provides broad material coverage; the SH7025 grade is chosen for toughness and edge stability across common steels and mixed workloads in turning.

How does the chipbreaker influence machining?
The one-sided chipbreaker on the EPGT 040102 SH7025 assists in controlled chip formation and evacuation, which supports consistent surface finish and reduces the risk of chip entanglement during external and internal turning.

Is this insert compatible with standard ISO holders?
Yes — the EPGT 040102 designation follows ISO geometry rules, and compatibility depends on matching form, clearance angle, tolerance class, fixation method, size and thickness to the intended holder.

Which features improve repeatability in production?
The coated carbide grade SH7025 and precise dimensional tolerances (0.2 mm corner radius, 1.59 mm thickness) deliver edge stability and consistent mounting, which together enhance repeatable machining performance.
