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

The CCMT09T304 T9215 is an ISO rhombic turning insert designed for external and internal turning, offering a robust balance of wear resistance and fracture toughness for continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215 for medium steel
• Rhombic ISO CCMT geometry for versatile turning
• 0.4 mm corner radius for balanced edge strength
• Cylindrical hole with single-sided countersink 40°–60°

Delivering high productivity through a durable cutting grade

The combination of a CVD-coated carbide substrate and the T9215 grade provides a reliable mix of wear resistance and fracture toughness, making the insert well suited to sustained production runs. This balance reduces unexpected tool changes and supports a consistent surface finish when machining medium steel. The material choice is focused on maintaining a stable cutting edge under continuous to slightly interrupted conditions, which translates directly into higher component throughput and lower tool-related downtime.

Compatibility and correct clamping ensure predictable results

Compatibility with a toolholder is determined by insert form, relief angle, tolerance class, fastening, size and thickness; the insert’s 7° relief angle and rhombic CCMT geometry require a matching holder and shim/clamp set to achieve the specified cutting geometry. Correct selection of holder and tightening torque prevents runout and ensures repeatable positioning, while the insert’s cylindrical hole with a single-sided countersink (40°–60°) secures positive clamping. For system assembly: use a matching outer holder or boring bar, the appropriate base shim/clamp and replacement screws.

Practical machining benefits and chip control

The single-sided chipbreaker design combined with a 0.4 mm corner radius gives a balanced compromise between edge strength and sharpness, supporting reliable chip formation and improved surface quality on turned parts. In practice, this geometry is particularly useful for medium-strength steels where moderate feeds and cutting depths are used; the insert’s features help avoid continuous long chips and aid evacuation when using standard chip control strategies. Expect consistent edge behaviour across batch runs, which simplifies process planning and quality control.

System-level advantages and economical use of tooling

As part of an ISO insert system, the item fits into a modular approach: the ISO CCMT insert can be stocked and paired with a selection of holders to cover a wide range of turning operations, reducing tooling variety and inventory costs. The 3.97 mm thickness, standard 09 size and the robust carbide construction contribute to a good lifetime under appropriate conditions, supporting predictable tool-change intervals and efficient production scheduling. Traceable identifiers like the manufacturer SKU reinforce procurement and reordering accuracy.

FAQ

What workpieces is this insert designed for?
The CCMT09T304 T9215 insert is primarily intended for medium steel turning, where its CVD-coated carbide grade combines wear resistance with fracture toughness for productive cutting.

How does the T9215 grade affect performance?
The T9215 grade offers increased wear resistance while retaining sufficient toughness to resist chipping, which supports higher productivity in continuous to lightly interrupted turning operations.

Which holder features are required for correct fitment?
Compatibility depends on insert form, 7° relief angle, tolerance class, fastening method, size and thickness; a matching CCMT-compatible outer holder or boring bar, correct shim/clamp and screws are required for secure clamping.

What does the 0.4 mm corner radius mean in practice?
A 0.4 mm corner radius balances edge strength and sharpness, providing improved surface finish potential while offering better resistance to edge damage compared with very small radii.

Can this insert handle interrupted cuts?
The insert is suitable for continuous to lightly interrupted cuts; heavy interruption may demand a different grade or geometry optimised for shock resistance.
