SPMT120404 T6215 Tungaloy indexable turning insert — CVD‑coated carbide for stainless steels, 0.4 mm radius

SPMT120404 T6215 Tungaloy‑Wendeplatte is a square, ISO‑standard insert designed for external and internal turning of stainless steels in stable to slightly interrupted conditions

• CVD-coated carbide grade T6215
• 12 mm square, 0.4 mm corner radius
• Single-sided chipbreaker for controlled chips
• Central hole with 40°–60° countersink

High productivity through optimised wear resistance and coating

The CVD‑coated carbide wear‑resistant grade T6215 delivers a balanced combination of toughness and resistance to abrasive wear, specifically tuned for turning stainless steels. This results in longer tool life and fewer index changes, reducing downtime and tool costs—advantages that support continuous, efficient production. The coating stabilises the cutting edge at elevated temperatures, which helps maintain a consistent surface finish even under long batch runs or continuous shifts.

Robust geometry for stable turning and reliable chip control

The square 12 mm plate with 0.4 mm corner radius and a 90° included angle offers a rigid cutting edge suitable for facing and general turning operations. The single-sided chipbreaker manages swarf for predictable evacuation, while the central hole with a cylindrical bore and a single‑side countersink (40°–60°) enables secure clamping in standard insert seats. The 11° clearance angle minimises rubbing and supports stable contact with the workpiece, improving dimensional repeatability and reducing the risk of built‑up edge formation during stainless steel machining.

System compatibility and selection guidance for efficient integration

As an ISO‑standard indexable plate, compatibility with a holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The insert works with standard external holders or boring bars when a matching seat, shim/clamp set and appropriate screws are used. For slightly interrupted cuts or heavier feeds, pairing the insert with a robust clamping system and the correct chipbreaker variant ensures consistent cutting forces and improved process reliability. Selection of the chipbreaker and grade should follow the workpiece alloy, machining parameters and machine rigidity.

Practical handling, assembly and application range

The insert forms part of a system comprising the ISO plate, a suited external holder or boring bar, a shim/clamp set and replacement screws to ensure safe fastening and repeatable positioning. Typical uses include external and internal turning of stainless steels under stable to slightly interrupted conditions; the grade performs well where a balance of wear resistance and edge stability is required. For mixed production, choosing the appropriate chipbreaker and monitoring cutting data will maximise tool life and maintain consistent component quality.

FAQ

What materials is this insert intended for?
The Tungaloy SPMT120404 T6215 insert is formulated for machining stainless steels, offering wear resistance and edge stability in stable to slightly interrupted turning operations.

Which holder types are compatible with this ISO insert?
Compatibility is defined by the insert form, clearance angle, tolerance class, fastening and thickness; use a matched external holder or boring bar with the correct shim/clamp set and screws for the SPMT120404 T6215.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius improves edge strength and surface finish while balancing cutting forces, making it suitable for general turning where a compromise between robustness and finishing is required.

Is this plate suitable for interrupted cuts?
Yes — the wear‑resistant grade T6215 and the plate geometry support stable to slightly interrupted cuts; however, machine rigidity and correct clamping remain important for repeatable results.
