CCMT 09T304 T9215 ISO turning insert by Tungaloy — for medium‑steel turning

The CCMT09T304 T9215 ISO turning insert is an indexable turning solution designed for external and internal turning in medium‑steel applications.

• CVD-coated carbide grade T9215
• 0.4 mm corner radius for precise profiles
• 7° clearance angle for stable cutting
• Rhombic CCMT shape with fixing hole

Increased productivity through a wear‑resistant grade

The CVD‑coated carbide grade T9215 delivers a balanced combination of wear resistance and fracture resistance, making it well suited to demanding, continuous or slightly interrupted turning operations on medium steels. Selecting this grade helps to sustain cutting performance over longer tool life, which in turn reduces tool change frequency and improves overall throughput. The chemical vapour deposition layer provides a hard, heat‑resistant finish that supports higher cutting speeds and consistent dimensional results.

Geometry engineered for dimensional accuracy and surface quality

The rhombic CCMT geometry with an included angle of 80° and a 0.4 mm corner radius provides controlled contact at the cutting edge for accurate form turning and profile work. A 7° clearance angle reduces rubbing behind the cutting edge, improving stability and lowering cutting forces; this supports predictable tool behaviour and better surface finish even under varying feed conditions. These geometric features are particularly valuable where repeatability and tight tolerances are required.

Secure clamping and quick integration into machining systems

As an ISO‑standard insert, this component integrates into common external holders or boring bars and is fastened using the centre hole configuration. The centre hole with a cylindrical hole plus single‑sided countersink (40°–60°) ensures reliable seat and repeatable positioning on the clamping set. System recommendations include a compatible outer holder or boring bar, a backing shim or clamp set, and replacement screws; this setup reduces downtime when exchanging inserts and supports consistent assembly alignment on the toolpost.

Practical application advice and selection criteria

Designed for turning, the insert performs best when matched with an appropriate chipbreaker and cutting parameters that reflect material condition and machine stability. For external and internal turning of medium steels, choose feeds and speeds that exploit the T9215 grade’s capabilities: higher cutting speeds for productivity while maintaining chip control for safety and surface quality. Where interrupted cuts or unstable setups occur, adjust depth of cut and reduce cutting speed to preserve edge integrity.

FAQ

Which materials is this insert best suited for?
The Tungaloy CCMT09T304 T9215 insert is optimised for medium‑steel machining; the T9215 grade combines wear and fracture resistance for productive turning in this material class.

Can this insert be used for internal turning?
Yes. The ISO‑standard geometry and the rhombic form allow use in both external and internal turning holders when the correct holder and clamping components are chosen.

What does the 0.4 mm radius affect in machining?
A 0.4 mm corner radius smooths the transition at the cutting edge, improving surface finish and distributing cutting forces to lower the risk of edge chipping during profile and finishing passes.

How is the insert fixed in the toolholder?
Fixing is via the centre hole: the plate uses a cylindrical hole with a single‑sided countersink (40°–60°) to ensure a stable seat and repeatable orientation when mounted in an ISO‑compatible holder.

Which chipbreaker should be selected for this grade?
Select a chipbreaker matched to workpiece material, feed rate and depth of cut; for medium steels and continuous cuts, a moderate‑duty chipbreaker that promotes short, controllable chips is recommended for this grade.
