CCMT09T302 GH730 CCMT turning insert — Tungaloy ISO rhombic insert, 0.2 mm radius

A CCMT09T302 GH730 indexable insert designed for ISO‑standard external and internal turning, delivering stable cutting edges and reliable chip control.

• GH730 grade for improved wear resistance
• 0.2 mm corner radius for fine surface finishes
• ISO rhombic CCMT form for holder compatibility
• Central hole with 40°–60° countersink for secure clamping

Predictable cutting performance with high edge stability

The GH730 carbide grade combines wear resistance and toughness to support consistent tool life under varying turning conditions. The CCMT09T302 geometry, with its 0.2 mm corner radius and 7° clearance, helps to balance surface finish and strength at the cutting edge; a small radius reduces chatter and improves finish at modest feeds, while the specified clearance angle minimises rubbing on the flank. The single‑sided chipbreaker offers controlled chip formation for many turning tasks, reducing the risk of built‑up edge and easing swarf management for shorter cycle times and fewer interruptions.

System compatibility and secure clamping for reliable results

Compatibility with the toolholder is governed by the insert’s form, ISO‑standard designation, clearance angle, tolerance class, clamping type, size and thickness. The rhombic CCMT form ensures interchangeability with matching external holders and boring bars, while the central hole with cylindrical bore plus one‑sided countersink (40°–60°) provides a repeatable seating and clamping interface. A complete system includes the indexable insert, a suitable external holder or boring bar, a shim/clamping set and replacement screws; selecting the correct combination is essential for repeatable geometrical accuracy and process stability.

Practical application scope and production benefits

Intended for general turning operations, the insert suits both external and internal turning where a moderate corner radius and robust edge are required. Its carbide construction and the GH730 grade prioritise productivity by extending tool life and maintaining a stable cutting edge under fluctuating loads. This leads to fewer insert changes, lower machine downtime and a more predictable part quality — advantages that directly support efficient production workflows and consistent surface finishes. For customers seeking guidance on grade selection or chipbreaker pairing for specific workpiece materials, targeted advice is available to align insert choice with machining stability and finish requirements.

FAQ

What turning tasks is this insert suited for?
The CCMT09T302 GH730 insert is intended for ISO‑standard external and internal turning where a moderate corner radius and reliable edge stability are required, covering common finishing and semi‑finishing operations.

How does the 0.2 mm corner radius affect the surface finish?
A 0.2 mm radius reduces the likelihood of chatter at moderate feeds and improves surface quality compared with larger radii; the GH730 grade helps maintain edge integrity to preserve finish over longer cycles.

Which holders are compatible with this insert?
Compatibility depends on form and ISO designation; holders designed for CCMT inserts with matching size, thickness and clamping style will fit. The central hole and countersink ensure secure seating in standard CCMT holders.

What is the benefit of the single‑sided chipbreaker?
A single‑sided chipbreaker provides consistent chip control in a range of cutting conditions, improving swarf handling and reducing the risk of chip entanglement during turning.

Can this insert be used for hardened materials?
The insert’s GH730 grade offers a balance of wear resistance and toughness suited to a broad spectrum of steels and common turning materials; for highly hardened alloys, verify suitability against specific hardness ranges and machining parameters.
