CCMT 09T312 AH6225 Tungaloy indexable insert — ISO turning insert for stainless steels, PVD-coated carbide

The CCMT09T312 AH6225 is an ISO-standard indexable turning insert designed for external and internal turning, offering a sharp yet robust cutting edge suited to medium machining of stainless steels.

• PVD-coated carbide AH6225 grade
• Universal for stainless steels
• 1.2 mm nose radius for versatility
• Rhombic 80° profile with hole

Consistent cutting performance for medium turning

The insert combines a PVD-coated surface with a carbide substrate to deliver consistent edge stability during variable conditions. The AH6225 grade is formulated as a universal option for stainless steels, giving a balance between a sharp cutting edge and wear resistance for medium cutting depths. This results in reliable cycle times and predictable tool life, which supports efficient turnover in batch and jobbing environments.

Predictable seating and secure clamping with ISO compatibility

Constructed to the ISO designation 09T312, the plate’s rhombic geometry and precise tolerances ensure compatibility with ISO turning holders when the form, relief angle, tolerance class, fastening method, size and thickness match. The insert has a cylindrical hole with a single-side countersink (40°–60°) which facilitates stable clamping and repeatable positioning. Clear specification of these mounting details reduces set-up time and helps avoid seating errors that could affect concentricity or surface finish.

Versatility and process benefits for surface finish and stability

A 1.2 mm nose radius paired with a single-sided chipbreaker provides a compromise between strength and surface quality: the radius allows secure cutting edge engagement, while the chipbreaker promotes controlled chip formation during turning. The 80° rhombic profile improves access for general-purpose turning and supports good surface integrity on external contours. For applications where medium machining and changing conditions are common, this Tungaloy insert helps maintain productivity with consistent results.
