SNMG 120408 AH6225 square indexable insert for turning (Tungaloy)

SNMG120408 AH6225 is a square ISO indexable insert for external and internal turning, engineered for reliable performance on stainless steels

• PVD-coated carbide grade AH6225
• Universal grade for stainless steels
• Double-sided chipbreaker design
• Square 12 mm plate, 90° cutting angle

Increased productivity through a stable cutting edge

The combination of a PVD-coated surface and a carbide substrate provides a balance of wear resistance and edge sharpness that supports medium‑duty turning operations. The AH6225 grade is formulated as a universal solution for stainless steels, so the insert maintains a consistent cutting edge under variable cutting conditions; this reduces the need for frequent tool changes and improves uptime. Where process reliability matters, the insert’s coating reduces adhesion and flank wear, helping to extend tool life while preserving part quality.

Precise geometry for predictable results

With a square form and a nominal 90° cutting angle, the insert delivers predictable tool paths for both external and internal turning. The 0.8 mm nose radius supports a good compromise between surface finish and edge strength, allowing stable performance on interrupted cuts while still enabling fine surface quality. The cylindrical hole and standard ISO dimensions ensure compatibility with common holders; insert clamping is determined by form, clearance, tolerance class, fixation, size and thickness, supporting straightforward integration into existing tool systems.

Versatile chip control for cleaner production

Equipped with a double-sided chipbreaker, the insert offers improved chip formation across a range of feeds and depths. The chipbreaker geometry helps to control swarf formation when machining ductile alloys such as stainless steels, decreasing the risk of chip entanglement and facilitating safer, cleaner production. Selecting the appropriate chipbreaker and grade according to workpiece material and machining stability delivers tangible benefits in process efficiency and surface integrity.

Practical fitment and handling advantages

The insert’s 4.76 mm thickness and 12 mm plate size conform to ISO standards, simplifying inventory management and replacement procedures. Being double-sided, each insert offers two usable cutting edges per side before indexing, which enhances cost efficiency in high‑volume shops. The insert is supplied in the SNMG 120408 format, making it straightforward to match with compatible external holders or tool shanks for turning tasks.
