CCGT CCGT09T304 SH725 turning insert (ISO rhombic) — Tungaloy

A CCGT09T304 SH725 ISO rhombic turning insert designed for external and internal turning applications, offering a tough coated carbide grade for changing engagement conditions.

• ISO rhombic CCGT09T304 geometry for wide compatibility
• Coated carbide grade SH725 for edge stability
• 0.4 mm nose radius for precise surface finish
• Cylindrical hole + single‑side countersink mounting

Reliable performance for diverse turning tasks

The insert is built on an ISO rhombic platform that ensures broad compatibility with standard toolholders; this geometry facilitates straightforward indexability and predictable cutting behaviour. The coated carbide substrate provides a balance between toughness and wear resistance, making the component suitable for both external and internal turning. By choosing a defined nose radius of 0.4 mm, machining yields consistent surface finish and dimensional control while keeping cutting forces moderate. The design emphasis is on repeatability and process stability, which is essential for series production and mixed-batch work.

Edge stability and suitability for variable engagement

The SH725 grade is a purpose‑developed coating and substrate combination that enhances edge robustness under varying depths of cut and interrupted cuts. This makes the insert particularly useful when tool size is small or when engagement conditions change frequently—common scenarios in subcontract and precision turning shops. The single‑sided chipbreaker contributes to controlled chip formation and evacuation, reducing the risk of recutting and thermal peaks. In practical terms, the result is fewer scrap parts and longer intervals between index changes, supporting efficient cycle times.

Mounting accuracy and mechanical fit for consistent results

Mechanical mounting features are decisive for insert behaviour; this item is supplied with a hole and a cylindrical hole with a single‑side countersink (40°–60°) to match standard clamping arrangements. The plate thickness of 3.97 mm and the ISO size designation ensure correct seating and clamping force distribution when paired with compatible holders. The 7° clearance angle reduces flank rubbing while maintaining adequate support for the cutting edge. Correct selection of holder geometry in line with these parameters ensures repeatable positioning and reduces vibration, which in turn improves surface integrity.

Materials, applications and practical guidance

Constructed from carbide with a protective SH725 coating, the insert is optimised for turning a broad range of materials when used with appropriate cutting data. Typical applications include finishing and medium‑duty roughing passes in steel and alloyed materials where edge security is a priority. For operators less familiar with grade selection: the coated carbide layer increases thermal resistance and wear life, while the substrate maintains toughness—together reducing the likelihood of chipping during variable cuts. Selection of feeds, speeds and coolant strategy should follow machining recommendations for the chosen workpiece material to exploit the insert’s advantages fully.

FAQ

What materials is this insert suited for?
The CCGT09T304 SH725 Tungaloy turning insert is designed for a wide range of metals; its coated carbide construction favours steel and alloyed materials where edge stability is essential.

How does the 0.4 mm nose radius affect surface finish?
A 0.4 mm nose radius on the insert delivers improved surface quality and dimensional control during finishing cuts while keeping cutting forces at manageable levels.

Is the insert compatible with standard ISO holders?
Yes — the ISO rhombic geometry and the specified hole/countersink configuration make the insert compatible with holders that accept CCGT‑form plates, provided the clamping and tolerance class match.

What advantages does the SH725 coating provide?
The SH725 coating enhances edge toughness and wear resistance, offering greater stability in applications with variable engagement or smaller tool sizes.

Can the insert be used for internal turning?
The insert is suitable for both external and internal turning when mounted in an appropriately sized and supported toolholder.
