SNMG120412 AH8005 Tungaloy insert – ISO turning insert with 1.2 mm corner radius

The SNMG120412 AH8005 is an ISO‑standard turning insert designed for stable external and internal turning of heat‑resistant alloys and other hard materials within production environments.

• PVD-coated carbide AH8005
• 1.2 mm corner radius for robust cuts
• Double-sided chipbreaker for versatility
• Cylindrical hole for secure clamping

High‑temperature wear resistance for productive machining

The combination of PVD‑coated carbide and the AH8005 grade is engineered for demanding turning tasks where heat and abrasion are significant factors. The coating reduces flank and crater wear at elevated temperatures, so tool life is extended and interruptions for index changes are less frequent. Where conventional grades show rapid wear on heat‑resistant alloys, this insert maintains a stable cutting edge, yielding consistent tolerances and fewer scrap parts. The coating also improves resistance to built‑up edge formation, which supports consistent surface integrity during long production runs.

Secure clamping and ISO compatibility for easy integration

Compatibility is assured by the ISO designation and by matching form, 0° clearance, tolerance class, attachment and size to the chosen holder. The cylindrical hole provides positive location and improved clamp stability, while the double‑sided geometry doubles the available cutting edges for cost‑effective indexing. With a 4.76 mm thickness and 12 mm size, the insert fits common ISO holders; the square plate form and 90° included angle suit both external and internal turning where a robust edge is required. Selection of the correct chipbreaker and grade should be matched to workpiece alloy and machining stability to exploit the insert’s performance.

Application advice for improved throughput and surface quality

For general turning, the double‑sided chipbreaker aids controlled chip formation across varying depths of cut and feeds, helping to avoid chip interference and tool damage. In more stable set‑ups, the insert delivers improved surface finish and repeatable dimensional accuracy; in interrupted cuts or unstable stoꞏk-holding scenarios, the 1.2 mm corner radius provides added edge strength and reduced risk of chipping. The insert is intended to be used as part of a system comprising an ISO insert, a matching external holder or boring bar, an underlay/clamping set and the correct replacement screws to ensure reliable fixation and repeatable results.
