CCMT 120404 T6215 — ISO rhombic turning insert by Tungaloy for turning

The CCMT120404 T6215 is an ISO-standard rhombic turning insert designed for external and internal turning of stainless steels, offering a wear-resistant CVD-coated carbide grade for stable machining.

• CVD-coated carbide for increased wear resistance
• ISO CCMT 120404 rhombic geometry
• 0.4 mm nose radius for controlled profiling
• 7° clearance angle for secure cutting
• With hole and 40°–60° countersink

Stable machining performance for stainless steels

The design focuses on delivering consistent metal removal when machining stainless steels under stable to lightly interrupted conditions. The combination of a CVD-coated carbide substrate and the specified grade provides improved resistance to adhesive wear and work-hardening tendencies typical of stainless alloys. For production environments, this means fewer insert changes and more predictable cycle times, supporting overall process reliability and higher throughput.

Coating and substrate engineered for long tool life

A carbide substrate with T6215 CVD-style coating gives the insert a balance of toughness and abrasion resistance. CVD coatings form a protective ceramic layer that reduces flank wear and helps maintain cutting-edge integrity at elevated cutting temperatures. In practice, this results in extended useful life compared with uncoated grades and more consistent dimensional control across batches, which benefits quality assurance and reduces scrap rates.

Geometry and edge preparation for predictable finishes

The rhombic ISO shape with an 80° included angle and a 0.4 mm nose radius supports both profiling and light finishing passes while limiting chatter in stable setups. A 7° clearance angle maintains positive cutting action and helps avoid rubbing on the flank, while the one-sided chipbreaker adapts chip flow to common turning feeds. Together these features produce repeatable surface quality and make toolpath planning more straightforward for workshop programmers and machinists.

System compatibility and practical integration

As an ISO-standard plate, the insert integrates into established toolholding systems when the holder is matched by form, clearance, tolerance class, fixing method, size and thickness. The plate is supplied with a central hole and a cylindrical hole plus single-sided countersink (40°–60°) to suit common clamping screws and shim combinations. Typical system components include an appropriate external holder or boring bar, support shim or clamping set and replacement screws to maintain assembly integrity and repeatable seat location.
