CCMT 09T304 T6215 Turning insert (rhombic) — Tungaloy

The CCMT09T304 T6215 is an ISO‑standard rhombic turning insert engineered for external and internal turning of stainless steel in stable to lightly interrupted conditions.

• CVD‑coated carbide for wear resistance
• Suitable for stainless steel machining under stable cuts
• Rhombic geometry with 80° cutting angle
• Cylindrical hole with 40°–60° countersink

Increased process stability through wear‑resistant grade

The CVD‑coated carbide in the T6215 grade delivers a combination of wear resistance and stable cutting behaviour that extends tool life in continuous turning operations. The robust coating reduces flank wear and maintains edge security under the light interruptions common in stainless steel turning, which in turn lowers scrap rates and improves overall productivity. This makes the insert particularly suited to serial production where repeatability is essential.

Improved surface finish and dimensional control

The insert’s rhombic geometry and 80° cutting angle provide a balanced cutting action that supports good surface quality while preserving tool strength. The 0.4 mm corner radius helps to absorb minor variances in feed, improving dimensional consistency on turned parts without compromising the edge. The 7° clearance reduces rubbing on the flank and helps to avoid work hardening on stainless grades, while the single‑sided chipbreaker assists chip formation for better swarf control and safer machining.

Practical compatibility and application guidance

As an ISO standard turning insert, the plate requires a matching holder defined by form, relief angle, tolerance class, fastening, size and thickness for correct seating. With a 3.97 mm thickness, the insert fits standard clamping systems and uses a cylindrical hole with single‑side countersink (40°–60°) for secure fixation. Select the chipbreaker and grade combination according to workpiece stability and the specific stainless steel alloy to gain the best balance of surface finish and tool life.

FAQ

What materials is this insert suited for?
The CCMT09T304 T6215 insert is designed primarily for stainless steel machining and performs best under stable to slightly interrupted turning conditions.

How does the 0.4 mm corner radius affect results?
A 0.4 mm corner radius offers a compromise between edge strength and surface finish, improving dimensional stability while still allowing a good surface quality on turned components.

Which holder features are required for correct seating?
Correct seating depends on matching form, clearance angle, tolerance class, fastening method, size and 3.97 mm thickness — use a holder compatible with ISO‑format rhombic plates and the insert’s 09 size.

What does the T6215 grade provide?
The T6215 grade, a CVD‑coated carbide, emphasises wear resistance and stable cutting behaviour, giving longer service life and reliable edge security in stainless steel turning.

Is chip control handled by the insert geometry?
Yes, the single‑sided chipbreaker is designed to improve chip formation and evacuation for the kinds of stainless steel turning applications this insert targets.
