SCMT120408 T6215 – Indexable milling insert (square, R0.8) by Tungaloy for milling

SCMT120408 T6215 is an indexable insert for milling, designed for productive machining of stainless steels in stable to lightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Square insert 12 × 12 mm, R0.8
• One-sided chipbreaker for controlled chips
• Cylindrical hole with countersink

Productive machining with CVD-coated carbide for stainless steels

The CVD coating on the T6215 grade delivers high wear resistance and stable edge life when machining stainless steels, translating into fewer tool changes and lower production costs per component. The use of carbide substrate with a protective layer reduces flank wear and helps maintain dimensional accuracy during longer engagements. For process planners, this means more predictable tool life and repeatable surface quality in batch production.

Secure seating and geometry that supports consistent results

Designed as a square insert with a cylindrical hole and one-sided countersink, the component ensures firm clamping in compatible cutter bodies. The 90° insert angle and R0.8 corner radius increase corner strength for interrupted or shoulder milling, while the 4.76 mm plate thickness aids rigidity under load. Correct seat matching between insert and cutter body is essential; when mounted in the appropriate Tungaloy milling system, the geometry supports accurate repeatability and reduced vibration.

Controlled chip formation and application flexibility

The one-sided chipbreaker promotes predictable chip flow and evacuation in common milling tasks such as face, shoulder, slot and contour operations. The 12 mm square format and medium corner radius make the insert suitable for a balance of robustness and edge definition, helping achieve consistent surface finish and tool performance. Used in stable to slightly interrupted cuts, the insert supports both roughing passes with effective chip control and finishing cuts where surface quality matters.

Selection guidance and practical handling notes

When choosing this indexable insert, confirm compatibility of insert seat, clamping screw and cutter family to ensure ideal performance; mismatched interfaces can compromise stability. The SCMT120408 T6215 benefits from matching cutter bodies specified for its seat geometry and through-hole style (cylindrical hole plus single-side countersink).

FAQ

What materials is this insert best suited for?
The SCMT120408 T6215 insert is optimised for stainless steels, offering wear resistance and stable cutting behaviour under the specified conditions.

Is the insert compatible with all milling cutter bodies?
Compatibility requires a matching insert seat and clamping design; the SCMT120408 must be used in cutter bodies designed for its seat, hole style and geometry.

What advantage does the R0.8 corner radius provide?
A 0.8 mm corner radius increases edge strength for interrupted cuts and shoulder milling while still allowing decent surface finish in finishing passes.

How does the one-sided chipbreaker affect machining?
The one-sided chipbreaker ensures controlled chip formation and evacuation, improving surface finish and reducing the risk of chip entanglement during milling.

Which coating and grade are used on this insert?
This insert features a CVD coating on a carbide substrate in the T6215 grade to enhance wear resistance when machining stainless steels.
