CCGT 09T304 SH725 Wendeplatten - Tungaloy

Take advantage of a tough, edge‑stable coated carbide grade and precise ISO rhombic geometry to improve process reliability and surface quality in turning operations; the combination of a 0.4 mm corner radius and a 7° relief angle provides controlled cutting behaviour and flexible use with a wide range of holders — order directly via Metav Werkzeuge or ask our consultants for holder compatibility.

CCGT 09T304 SH725 indexable insert for turning — Tungaloy

CCGT 09T304 SH725 is an ISO‑standard rhombic indexable insert designed for external and internal turning, combining a 0.4 mm corner radius with a 7° relief angle for stable performance in variable engagement conditions.

• ISO rhombic insert geometry
• SH725 coated carbide for edge stability
• 0.4 mm corner radius for fine finishing
• Central hole with countersink for secure clamping

Reliable performance from a tough coated grade

The SH725 coating variant is a coated carbide grade optimised for toughness and cutting‑edge stability, making it suitable where tool engagement can vary or where smaller tooling is used. The grade's composition supports consistent chip formation and extended edge life in interrupted cuts, which in turn reduces unplanned tool changes and contributes to higher overall productivity. By selecting a robust grade such as this, process planners gain a measurable advantage in machining repeatability and component quality.

Geometry and clamping features that aid precision

The insert's rhombic form (size 09) and 80° included angle deliver predictable approach geometry for turning tasks, while the 0.4 mm corner radius balances edge strength with the ability to produce fine surface finishes. The 7° relief angle reduces rubbing and heat generation at the flank, improving tool life in many turning applications. The plate is 3.97 mm thick, and the centre is prepared with a cylindrical hole plus single‑side countersink (40°–60°) to ensure secure, repeatable clamping in compatible holders. These geometric details are decisive when matching inserts to clamping systems and fixture tolerances.

Practical selection guidance for machinists and engineers

Compatibility depends on insert form, relief angle, tolerance class, clamping method, size and thickness; therefore, choose the matching external holder or boring bar, underplate/shim and fastening screws that correspond to the insert geometry. The included single‑sided chipbreaker is aimed at predictable chip control for many turning tasks; selecting an alternative chipbreaker and the SH725 grade according to workpiece material and machining stability will help to optimise cycle time and surface integrity. The insert is intended primarily for turning and integrates into standard ISO indexable insert systems for straightforward tool‑room planning.

FAQ

What materials is this insert best suited for?
The CCGT 09T304 SH725 insert is intended for turning a broad range of materials where a tough, edge‑stable grade is required; the SH725 coated carbide performs particularly well in applications with variable engagement and interrupted cuts.

How does the 0.4 mm corner radius affect surface finish and tool life?
A 0.4 mm corner radius offers a compromise between increased edge strength and the ability to produce a fine surface finish; the radius helps to distribute cutting forces and extend edge life under standard turning conditions.

Which holder features are required for secure clamping?
Holders compatible with the ISO CCGT form, accepting size 09 plates with a central cylindrical hole and single‑side countersink, are required to ensure repeatable, secure clamping for the Tungaloy indexable insert.

Is the chip control suitable for finishing passes?
The single‑sided chipbreaker on this insert supports controlled chip formation and can be used for finishing where stable cutting conditions are present; pairing the insert grade with the correct feed and speed settings improves surface integrity.

What identifies the product and where is it from?
This item is the CCGT 09T304 SH725 indexable insert (SKU 6737133‑Tungaloy) manufactured by Tungaloy and designed for ISO turning applications.
