EPGT 040102 SH725 ISO turning insert for turning — Tungaloy

The EPGT040102 SH725 is an ISO‑standard rhombic turning insert engineered for external and internal turning, offering a tough, edge‑stable grade and a single‑sided chipbreaker for varying engagement conditions

• SH725 coated carbide grade for stable cutting
• ISO rhombic insert, size 04, 11° clearance
• Nose radius 0.2 mm for fine finish
• Cylindrical hole with one‑sided countersink

High productivity from a tough, edge‑stable grade

The core advantage of this indexable insert is the SH725 coating and substrate combination, designed to deliver stable cutting edges and consistent performance under fluctuating engagement conditions. The coated carbide composition provides toughness that reduces the risk of chipping during interrupted cuts and when using smaller toolholders. As a result, machining cycles become more predictable and tool change frequency is reduced, supporting a smoother production flow and lower unplanned downtime.

Precise mounting and secure clamping for repeatable results

Built to the ISO series format, the insert’s rhombic geometry and defined tolerances ensure compatibility with standard holders when the form, clearance, tolerance class, fixation, size and thickness match. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) and an 11° clearance, which together enable reliable clamping and accurate seating on the backing pad or clamp set. This mechanical security improves vibration resistance and contributes to a consistent surface finish and tool life from one seat‑off to the next.

Versatile application range and system integration

Intended for general turning, the insert supports both external and internal operations; the 0.2 mm nose radius is optimised for fine surface quality while the 75° geometry assists chip formation in common turning tasks. Selection of the single‑sided chipbreaker and the SH725 grade should be matched to the workpiece material and machine stability for best results. Typical system assembly comprises the ISO insert, a matching external holder or boring bar, a backing pad/clamp set and spare screws, enabling fast replacement and minimal setup time at the machine.

FAQ

What materials is this insert best suited for?
The SH725‑grade coated carbide insert is formulated for broad material coverage and is particularly suitable where a tough cutting edge is required; material selection should be matched with the chipbreaker and machine stability.

How does the hole style affect clamping?
The cylindrical hole with a one‑sided countersink (40°–60°) ensures secure seating on standard backing pads and clamp sets, reducing micro‑movement and improving repeatability for the EPGT040102 insert.

Can the insert be used for both external and internal turning?
Yes, the ISO‑format rhombic insert is intended for both external and internal turning operations when paired with the appropriate holder or boring bar.

What surface finish can be expected with a 0.2 mm nose radius?
A 0.2 mm nose radius provides a balance between surface quality and tool strength; it is well suited for fine finishes while maintaining edge stability under common turning conditions.

What should be considered when choosing the chipbreaker?
Select the chipbreaker based on the workpiece material, depth of cut and machine rigidity; the single‑sided chipbreaker on this insert is optimised for stable chip control in typical turning scenarios.
