CCMT 09T304 GH730 Wendeplatten - Tungaloy

Take advantage of the combination of GH730 wear resistance, a 0.4 mm corner radius and ISO compatibility for steady, predictable turning performance; order original inserts via Metav Werkzeuge or request advice from our consultants to match grade and chipbreaker to the specific machining task.

CCMT09T304 GH730 — CCMT turning insert by Tungaloy, 0.4 mm corner radius

CCMT09T304 GH730 is an ISO‑standard indexable turning insert engineered for both external and internal turning operations where edge stability and repeatable wear behaviour are required.

• ISO-standard rhombic CCMT geometry
• GH730 grade for wear resistance
• 0.4 mm corner radius for versatile turning
• Cylindrical hole with 40°–60° countersink

Consistent tool life through a balanced carbide grade

The GH730 composition, supplied by Tungaloy and applied to this indexable insert, provides a deliberate balance of wear resistance and toughness that helps maintain cutting-edge integrity under varied turning conditions. As a cemented carbide product, the insert resists abrasive wear while the grade optimises edge support; this reduces the frequency of edge changes and contributes to a more predictable tool life. Selecting a matching chipbreaker and application-specific grade minimises downtime and supports consistent component tolerances.

Precise geometry for reliable mounting and repeatability

Designed to ISO specifications, the rhombic CCMT form ensures compatibility with matching holders when the shape, relief angle, tolerance class, clamping style, size and thickness are observed. The insert features an 80° included angle and a 7° relief angle, with a plate thickness of 3.97 mm, which together provide a secure seat in the toolholder and repeatable positioning for serial production. The through-hole is cylindrical with a single‑side countersink (40°–60°) to suit standard clamping systems, aiding fast replacement and stable performance in both external and internal operations.

Practical benefits for everyday turning workpieces

With a corner radius of 0.4 mm, the insert offers a compromise between strength and finish capability: small enough for tighter radii yet robust enough to withstand interruptions or moderate feeds. The single-sided chipbreaker geometry supports controlled chip formation in a wide range of turning tasks; choosing the correct chipbreaker and the GH730 grade helps manage temperature and chip flow, which improves surface quality and reduces secondary operations. System assembly typically comprises the ISO insert, a suitable external holder or boring bar, a shim/clamp set and replacement screws for quick servicing and minimal downtime.

Integration into production and selection guidance

For smooth integration into machining routines, consider the workpiece material, machine stability and cutting parameters when specifying the insert and holder. The insert is intended for turning and is part of an ISO insert system; matching the insert geometry and the GH730 material grade to the part geometry and cutting strategy yields the best balance of productivity and component quality. If further clarification is needed on holder compatibility or optimal cutting data, our technical team can provide guidance and help define the most economical setup.

FAQ

What materials is this insert intended for?
The CCMT09T304 GH730 indexable turning insert is designed for general turning; the GH730 grade complements the geometry by providing a balance of wear resistance and toughness suitable for a broad range of turning applications.

How does the 0.4 mm corner radius affect cutting results?
A 0.4 mm corner radius on the CCMT09T304 GH730 insert offers a compromise between edge strength and surface finish, enabling moderate feeds with good edge life while allowing tighter profile details than larger radii.

Which holders are compatible with this ISO CCMT insert?
Compatibility depends on holder form, relief angle, tolerance class, clamping style, size and thickness; the CCMT09T304 GH730 fits standard CCMT holders when these parameters match the insert specifications.

Is the insert supplied as original Tungaloy product?
Yes, the CCMT09T304 GH730 insert is supplied as an original, factory‑new product from Tungaloy; reference SKU 6820969‑Tungaloy for ordering and verification.
