CCMT120412 T6215 — CCMT turning insert for stainless-steel, CVD-coated carbide by Tungaloy

CCMT120412 T6215 is a rhombic ISO turning insert designed for external and internal turning of stainless steel under stable or slightly interrupted conditions.

• CVD-coated carbide grade T6215
• Suitable for stainless-steel turning
• Rhombic 80° geometry, 7° clearance
• Central hole with cylindrical bore and countersink

Reliable performance for stainless-steel machining

The combination of a CVD-coated surface and a wear-resistant carbide substrate provides predictable tool life and steady cutting behaviour when machining rostfreier Stahl (stainless steel). As a result, process stability is improved and scrap rates are reduced. The T6215 grade is formulated for abrasive and adhesive wear resistance, which means longer intervals between indexings and fewer unscheduled tool changes — a clear advantage where uptime and surface quality matter.

System compatibility and quick index change for efficient production

Built to ISO dimensions, the insert integrates with standard holders so replacement is straightforward and repeatable. The rhombic 80° shape and central hole with a 40°–60° countersink ensure secure clamping and consistent seating in the cutter body. Because compatibility depends on form, clearance angle, tolerance class, attachment method, size and thickness, the ISO designation simplifies selection and reduces downtime when switching inserts, supporting faster tool setup and predictable process control.

Geometry and features that support finishing and roughing tasks

The 1.2 mm corner radius provides a balance between edge strength and achievable surface finish; a larger radius increases robustness for heavier cuts, while a smaller radius favours finer finishes. The 7° clearance minimises flank rubbing and helps maintain sharp cutting action, and the single-sided chipbreaker is optimised for controlled chip formation when turning stainless steel under typical setups. The plate thickness of 4.76 mm and the 12 mm inscribed circle suit a wide range of external and internal turning applications without compromising rigidity.

Practical guidance for integration into production

Intended for external and internal turning, select the chipbreaker and grade to match workpiece material, cutting mode and machine-tool rigidity. For stable setups the T6215 grade will deliver extended life; for more interrupted operations or specialised alloys consider evaluating holder stability and smaller depth of cut steps. The ISO-standard format facilitates stocking and rapid replacement, helping to keep cycle times low and maintain consistent component quality.

FAQ

What materials is this insert suitable for?
The CCMT120412 T6215 Tungaloy turning insert is optimised for rostfreier Stahl (stainless steel) and delivers wear resistance suited to stable and lightly interrupted turning operations.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO dimensions; compatibility is determined by shape, clearance angle, tolerance class, attachment method, size and thickness, so matching the holder to these parameters ensures proper fit and clamping.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm radius enhances edge strength for heavier cuts while still allowing a good surface finish; it represents a compromise between robustness and the ability to achieve finer surface textures.

What is the benefit of the CVD coating on this grade?
The CVD-coated surface on the T6215 grade increases resistance to abrasive and adhesive wear, extending effective tool life and maintaining cutting-edge stability in stainless-steel turning.

Does the insert have a specialised chipbreaker?
Yes, the insert features a single-sided chipbreaker designed to control chip formation during turning of stainless steel, improving process reliability and surface integrity.
