EPGT 040104 SH7025 — ISO turning insert (rhombic, with hole) by Tungaloy

The EPGT040104 SH7025 is an ISO-standard rhombic turning insert for external and internal turning, featuring a one-sided chipbreaker and a cylindrical hole with single-side countersink for secure clamping.

• Tough SH7025 coated carbide grade for stable edges
• Rhombic insert form with 11° clearance angle
• Central hole with cylindrical seat and 40°–60° countersink
• 0.4 mm corner radius for versatile engagement

Longer service life through a tough, edge-stable grade

The coated carbide SH7025 is engineered for edge stability and consistent wear behaviour, which is particularly beneficial in small tools or when engagement conditions vary. The composition and coating promote predictable abrasion, reducing the frequency of index changes and supporting uninterrupted production cycles. This stability translates into fewer interruptions and improved component consistency when machining both external and internal features.

Geometry that improves accuracy and repeatability

A rhombic plate form with a defined 11° clearance angle and a 0.4 mm corner radius delivers a balance between strength and cutting precision. The small corner radius reduces cutting forces on interrupted cuts while still providing sufficient edge support for smoother surfaces. The specified geometry helps maintain dimensional accuracy across a series of parts, making the insert suitable for repeatable turning tasks where surface finish and tolerance adherence matter.

Secure mounting and straightforward system compatibility

The insert incorporates a cylindrical central hole with a single-sided countersink (40°–60°) to ensure firm seating and positive clamping in ISO-compatible holders. Compatibility with toolholders depends on form, clearance angle, tolerance class, fastening, size and thickness; the 1.59 mm plate thickness and ISO designation align with common external holders and boring bars. Clear mechanical seating reduces micro-movement at the cutting edge and supports process stability.

Practical advantage for workshop workflows

Specified as an ISO-series turning insert, this plate integrates into established tool systems with minimal adjustment. The one-sided chipbreaker aids chip control for many turning operations, and the compact design suits small-diameter tools or constrained setups. For shops seeking dependable inserts for a variety of steels and mixed production runs, the combination of grade, geometry and mounting features yields a simple route to dependable, productive machining.

FAQ

What holders are compatible with this insert?
Compatibility is determined by insert form, clearance angle, tolerance class, fastening, size and thickness; the EPGT 040104 SH7025 fits standard ISO rhombic holders and matching boring bars when those specifications match.

Which materials can be machined with this grade?
The SH7025 coated carbide grade is a tough, edge-stable choice suited to a broad range of steels and mixed-material batches; select the chipbreaker and cutting parameters according to workpiece behaviour.

How does the central hole influence clamping?
The cylindrical hole with a single-side countersink (40°–60°) provides positive seating and reliable clamping in ISO-compatible toolholders, reducing micro-movement at the cutting edge.

Is the insert suitable for small-diameter tools and interrupted cuts?
Yes; the relatively small 0.4 mm corner radius and the SH7025 grade are targeted at applications with changing engagement conditions and smaller tools, offering robustness for interrupted cuts.

How is the chip control achieved?
Chip control is supported by the one-sided chipbreaker; matching the breaker geometry and feed rates to the material and operation improves chip evacuation and surface quality.
