CCMT120404 T6215 CCMT turning insert – Tungaloy

CCMT120404 T6215 is an ISO-format indexable turning insert designed for external and internal turning of stainless steels under stable to mildly interrupted conditions.

• ISO CCMT geometry for standard toolholders
• CVD-coated carbide for improved wear resistance
• 0.4 mm corner radius for profile stability
• Single-sided chipbreaker for predictable chips

Consistent performance when machining rostfreier Stahl

The ISO-format insert delivers a balance of edge security and surface finish when machining rostfreier Stahl; the CVD-coated carbide substrate resists abrasive and adhesive wear common with chromium-rich alloys, reducing flank‑wear progression. The moderate 0.4 mm corner radius supports dimensional control and simple finishing passes without aggressive feed steps, while the single-sided chipbreaker helps form compact chips in typical turning operations. These properties translate into fewer insert changes and more stable cycle times on serial production runs.

Reduced process risk through clear holder compatibility

Compatibility depends on geometry, clearance angle and tolerance class; the ISO CCMT120404 designation clarifies fitment with commercially available CCMT holders. The insert's 80° diamond shape and 7° clearance match common holder profiles, and the central cylindrical hole with one-sided countersink (40°–60°) secures reliable clamping and repeatable seating. Specifying the insert by its ISO code and thickness simplifies tool inventory and minimises setup errors, improving first‑pass yield in workshop environments.

Durable edge life and predictable chip control

The T6215 grade is a CVD-coated carbide designed for wear resistance during turning of rostfreier Stahl in stable to lightly interrupted cuts. The single-sided chipbreaker is tuned to the grade and geometry to promote controlled, detachable chips that clear reliably from the cut, reducing the risk of surface damage and machine downtime. When paired with an appropriate holder and cutting parameters, the combination enhances productivity and reduces the frequency of regrinds or insert swaps.
