CCMT120412 T6215 Tungaloy indexable insert for turning

A CCMT120412 T6215 indexable insert from Tungaloy designed for precision turning of rostfreier Stahl with a rhombic CCMT geometry and a single-sided chipbreaker.

• CVD-coated carbide grade T6215
• Optimised for rostfreier Stahl turning
• Rhombic CCMT geometry, 7° clearance
• 1.2 mm corner radius for robust edge

High-performance cutting for rostfreier Stahl with consistent wear resistance

The CVD-coated carbide grade T6215 provides a balance between wear resistance and edge toughness that is particularly suited to machining rostfreier Stahl. The CVD coating reduces adhesive wear and extends tool life under stable to slightly interrupted cuts, which means fewer insert changes and more continuous production time. Explained simply, a CVD-coated insert forms a thin, hard layer over the carbide substrate that improves resistance to heat and abrasion; this translates into longer life on demanding rostfreier Stahl workpieces and more predictable process windows for industrial turning operations.

Geometry and compatibility that simplify tool selection

The rhombic CCMT geometry with an included angle of 80°, a 7° clearance and a 1.2 mm corner radius makes the insert compatible with a wide range of external holders and shanks. Compatibility is determined by the insert form, clearance angle, tolerance class, mounting method, size and thickness; having standard ISO geometry ensures that the insert fits common holder families and reduces setup complexity. The insert’s central hole—with a cylindrical bore and a one-sided countersink (40°–60°)—permits secure clamping while enabling easy indexing, supporting stable cutting even when machining interrupted surfaces.

Practical system design and application guidance for reliable production

The insert is supplied as part of a system comprising an ISO indexable insert, the correct external holder or shank, a shim or clamping kit and replacement screws; selecting the appropriate chipbreaker and grade according to workpiece material and process stability is decisive. The single-sided chipbreaker on this insert supports controlled chip formation for common turning operations, improving surface finish and swarf handling. For shop-floor application: pair the insert with a suitably rigid holder, adjust feeds and speeds conservatively at first, and exploit the insert’s strengths—CVD-coated carbide, robustness and geometric standardisation—to improve process stability and reduce non-productive time.

FAQ

What materials is the CCMT120412 T6215 Tungaloy indexable insert best suited to machine?
The CCMT120412 T6215 Tungaloy indexable insert is optimised for machining rostfreier Stahl and performs well under stable to lightly interrupted turning conditions.

How does the T6215 grade compare for tool life and toughness?
Grade T6215 offers an emphasis on wear resistance through CVD coating while retaining sufficient toughness, so the CCMT120412 T6215 insert provides longer life on abrasive rostfreier Stahl workpieces without excessive chipping.

What should be considered when choosing a holder for this insert?
Holder selection depends on the CCMT form, 7° clearance, tolerance class, mounting and plate thickness; the insert’s ISO CCMT geometry ensures compatibility with many standard external holders and shanks.

Can this insert be used for interrupted cuts?
Yes, the CCMT120412 T6215 insert is suitable for stable to mildly interrupted cuts; the robust 1.2 mm corner radius and CVD-coated carbide construction help withstand occasional interruptions.

What is the function of the central hole and countersink on this insert?
The cylindrical hole with a one-sided countersink (40°–60°) provides secure and repeatable clamping in compatible holders, simplifying indexing and maintaining cutting stability.
