Consistent results with PVD-coated carbide for stainless steels

The combination of PVD-coated carbide and the AH6225 grade provides a balance between edge sharpness and wear resistance, which is particularly beneficial when machining stainless steel. The coating enhances thermal stability and reduces built-up edge formation, so operators experience fewer interruptions and more predictable tool life. As an ISO-standard rhombic insert, the geometry ensures reliable seating and repeatable orientation in compatible holders, contributing to process stability in batch production and single-part runs.

Precision geometry and chip control that improve productivity

The 55° rhombic shape with a 1.2 mm corner radius gives a robust cutting edge that tolerates moderate interruptions while maintaining surface quality. The double-sided chipbreaker and the cylindrical hole support consistent chip formation and evacuation, lowering the risk of tool damage and workpiece marks. These attributes result in measurable gains in efficiency: reduced rework, fewer insert changes, and more time on productive machining. For applications where surface finish and repeatability matter, the design aids both efficiency and component quality.

Compatibility guidance and system setup for reliable mounting

Compatibility depends on holder form, clearance angle (noted here as 0°), tolerance class, fastening method, size and thickness. The insert requires a matching external holder or boring bar, plus an underlay/clamping set and spare screws for secure assembly. As part of an ISO indexable turning inserts system, it integrates into standard toolholders when those parameters align. For external and internal turning, confirm seat geometry and clamping method to ensure the stable cutting edge performs as intended under varying cutting conditions.
