• Suitable for stainless steel turning
• Double-sided chipbreaker, cylindrical hole
• Corner radius 1.2 mm, plate thickness 4.76 mm

Longer tool life and consistent productivity from a CVD-coated grade

This insert is made from cemented carbide with a CVD-coated surface and the T6215 grade, delivering improved wear resistance in the typical work range for stainless steels. The coating reduces flank wear and stabilises the cutting edge, which translates into longer tool life and fewer indexings per component. For production environments seeking repeatable cycle times, the combination of substrate and coating supports predictable performance and reduced downtime due to tool changes.

Geometry and mechanical features that support precision turning

The rhombic 55° geometry with a nose radius of 1.2 mm and a 0° relief angle gives a balanced compromise between cutting force distribution and surface finish. The insert is double-sided with a cylindrical locating hole, enabling economical use of both edges and secure clamping in standard ISO-compatible holders. Compatibility with a holder is determined by the insert form, relief angle, tolerance class, clamping method, size and thickness; matching those parameters ensures correct seating and repeatable alignment in the toolholder.

Optimised for stainless steel and practical machining scenarios

Designed specifically for stainless steel turning, this grade performs well under stable cuts and tolerates light interruptions typical of groove entries or parting operations. The double-sided chipbreaker encourages reliable chip control, reducing heat concentration at the cutting edge and helping to maintain surface integrity on the workpiece. Where surface finish and dimensional accuracy are priorities, the insert’s construction supports consistent results with standard turning feeds and speeds adapted to stainless steel.

System approach and workshop advantages

The insert forms part of an ISO indexable insert system: a matching external holder or boring bar, a supporting shim or clamp set and replacement screws are required for complete assembly. Using standardised inserts simplifies tool management and reduces inventory complexity. The item is identified by manufacturer references for easy reordering, and its predictable wear behaviour supports planned tool-change intervals, improving overall process stability on the shop floor.

FAQ

What materials is this insert suitable for?
The DNMG150412 T6215 insert is specified for turning stainless steel; the CVD-coated carbide grade T6215 provides wear resistance suitable for stable to slightly interrupted cuts in these materials.

How does the insert mount in a toolholder?
Mounting requires an ISO-compatible external holder or boring bar with the correct pocket for a rhombic 55° insert, plus the appropriate shim/clamp set and fastening screw; the cylindrical hole ensures positive location.

How many cutting edges are available per insert?
This is a double-sided insert; flipping and indexing allow both cutting edges to be used, extending the usable life before replacement.

Is the relief angle standard for ISO holders?
The insert features a 0° relief angle, which is a common specification for certain turning operations; compatibility should be confirmed against the chosen holder’s pocket geometry and tolerance class.

What advantages does the T6215 grade bring?
T6215, a CVD-coated carbide grade, improves wear resistance and edge stability when machining stainless steel, reducing flank wear and supporting consistent surface finish over longer tool life.
