DCET 070202 SH725 turning insert for turning by Tungaloy — 55° rhombic, 7° clearance

The DCET070202 SH725 is an ISO-standard rhombic indexable insert designed for external and internal turning, optimised for varying engagement conditions and smaller-tool applications.

• Rhombic insert DCET 55° geometry
• Coated carbide grade SH725 for edge stability
• 7° clearance angle for reliable cutting
• Cylindrical hole with single-sided countersink

Consistent cutting performance through a tough coated grade

The SH725 grade is a coated carbide developed for edge stability under fluctuating cutting conditions. Its formulation emphasises toughness, which helps maintain the integrity of the cutting edge when tool engagement varies or when smaller toolholders are used. This results in steadier machining and reduced risk of unexpected edge chipping, supporting repeatable production runs where process reliability is required. The combination of coating and substrate is selected to extend effective tool life while simplifying tool-change planning.

ISO conformity that simplifies toolholder selection and integration

As an ISO-standard insert, the component benefits from defined geometry and dimensioning; ISO designation makes compatibility assessment straightforward. Correct integration is determined by insert form, clearance angle, tolerance class, clamping method, size and thickness. Matching these parameters to the chosen external holder or boring bar avoids unnecessary rework and secures the insert reliably during turning operations. Clear documentation of these criteria supports predictable set-up times and consistent clamping behaviour across machines.

Geometry and chip control for efficient turning operations

The rhombic 55° lead angle provides a versatile cutting orientation for both external and internal turning, balancing approach angle and cutting edge accessibility. The 7° clearance reduces rubbing on the flank face, improving surface finish and lowering heat generation. A single-sided chipbreaker offers controlled chip formation for many turning tasks, while the cylindrical hole with a one-sided countersink (40°–60°) ensures positive and repeatable clamping. The small 0.2 mm corner radius adds versatility for finishing passes without compromising edge strength, and the 2.38 mm thickness maintains sufficient rigidity in the insert seat.

System-minded design for practical shop-floor use

The insert forms part of a typical turning system comprising the ISO insert itself, a compatible external holder or boring bar, a suitable shim/clamping set and replacement screws. Selecting the correct chipbreaker and grade for the specific workpiece material and machine stability ensures optimal results. The modular nature of ISO inserts allows rapid replacement and inventory management, promoting uptime and consistent component quality in production environments where tool change frequency and process repeatability matter.

FAQ

Is the insert suitable for both external and internal turning?
The DCET070202 SH725 insert is designed for external and internal turning applications and is compatible with ISO-standard holders when matched for form, size and clamping.

What advantages does the SH725 grade offer?
The SH725 coated carbide grade provides enhanced toughness and edge stability, making it particularly suitable for smaller tools and operations with variable engagement conditions.

What is the corner radius and thickness of the insert?
The insert has a corner radius of 0.2 mm and a thickness of 2.38 mm, offering a compromise between finishing capability and edge strength.

How is the insert secured in the holder?
This insert features a cylindrical hole with a one-sided countersink (40°–60°) for positive clamping; the correct holder and clamping set ensure reliable fixation during turning.

Can the chipbreaker be used for different materials?
The single-sided chipbreaker provides controlled chip formation; selection of the exact chipbreaker and grade should be matched to the workpiece material and machining stability for optimal results.
