CCMT 09T304 GH730 turning insert — ISO rhomboid, 80° approach angle (Tungaloy)

A CCMT09T304 GH730 indexable insert engineered for external and internal turning, featuring a rhomboid form, a single-sided chipbreaker and a cylindrical hole with a one-sided countersink.

• ISO rhombic insert, 80° cutting angle
• GH730 grade for wear resistance and toughness
• 0.4 mm corner radius for precise finishing
• Cylindrical hole with 40°–60° countersink

Consistent machining performance for turning

The CCMT09T304 is built on a carbide substrate and the GH730 grade, which complements the insert geometry to provide a deliberate balance between wear resistance and edge toughness. This balance reduces unexpected tool failure and sustains cutting performance across longer tool life cycles, making the insert suitable for a wide range of turning tasks. The integrated chip control and edge stability lead to fewer interruptions during batch runs and a more predictable production output.

Secure seating and accurate tool engagement

As an ISO-standardised rhomboid insert with an 80° approach angle and a 3.97 mm plate thickness, the component is dimensioned to ensure repeatable seating in compatible holders. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; the supplied cylindrical hole with a one-sided countersink (40°–60°) facilitates secure clamping and accurate axial positioning. Reliable mechanical engagement reduces micro-movement during heavy cuts, which in turn improves dimensional consistency on turned components.

Improved productivity through stable chip control and finishing

The single-sided chipbreaker provides optimised chip formation for many turning operations, helping to evacuate swarf efficiently and maintain a stable cutting zone. The 0.4 mm corner radius offers a compromise between surface finish and edge strength, enabling fine finishing passes without sacrificing robustness. Together, the geometry and grade support higher metal removal rates where process security is required, while lowering the frequency of insert changes — a clear contribution to operational economy and time-saving on the shop floor.

FAQ

Is this insert suitable for both external and internal turning? Yes. The CCMT09T304 GH730 insert is designed for external and internal turning; selection of the chipbreaker and grade should be matched to the workpiece material and the machining conditions.

What determines compatibility with a tool holder? Compatibility is set by insert form, relief (frewinkel), tolerance class, fastening method, size and thickness; the CCMT09T304’s cylindrical hole plus countersink ensures secure clamping in holders designed for ISO rhomboid inserts.

Which machining benefits does the GH730 grade provide? The GH730 grade adds a balance of wear resistance and toughness to the geometry, enhancing edge stability and extending useful tool life in a variety of turning operations.

How does the 0.4 mm corner radius affect surface finish? A 0.4 mm corner radius offers improved edge strength while enabling a fine surface finish on finishing passes; it is suitable where dimensional accuracy and good surface quality are required.

What is the purpose of the single-sided chipbreaker? The single-sided chipbreaker is engineered to control chip formation and evacuation during turning, promoting a stable cutting zone and reducing the risk of chip interference with the workpiece.
