SCMT120412-PM AH725 Tungaloy turning insert — PVD-coated carbide, 1.2 mm nose radius

SCMT120412-PM AH725 Tungaloy turning insert is an ISO-format indexable turning plate designed for general external and internal turning where process stability and material versatility are required.

• PVD-coated AH725 carbide grade
• 1.2 mm nose radius for robust edge
• Square ISO insert, 90° included angle
• Chipbreaker PM for general turning tasks

Consistent wear resistance for mixed-material production

The PVD-coated AH725 grade combines a wear-resistant surface layer with a tough carbide substrate to balance edge stability and longevity. This configuration is particularly effective where workpieces vary between Stahl and rostfreier Stahl, since the coating reduces flank wear and the substrate resists chipping under interrupted cuts. The ISO-format indexable design simplifies tool changes and supports predictable tool life, which improves planning and reduces unplanned machine downtime.

Geometry engineered for productivity and finish

The square plate geometry with a 90° included angle and a 1.2 mm nose radius offers a compromise between edge strength and surface finish: the larger nose radius stabilises the cutting edge for heavier passes, while the 7° clearance angle maintains good cutting clearance and reduces rubbing. The chipbreaker PM is matched to the insert form to control chip flow in typical turning operations, and the insert’s hole and countersink arrangement ensure secure clamping in compatible holders. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness of the holder system.

Designed for process security and ease of integration

As an ISO-standard turning insert, the SCMT120412-PM can be integrated into existing tool systems with minimal adaptation. The AH725 composition is intended as a universal, breakage-resistant grade suitable for smaller tools and setups demanding high process security. Reduced frequency of unexpected edge failures translates into lower tool consumption and more consistent component tolerances, supporting efficient production workflows and better first-pass yields.

FAQ

What materials is this insert suitable for?
The SCMT120412-PM AH725 insert is designed for a broad material range, with the AH725 grade particularly suited to Stahl and rostfreier Stahl applications where process security is important.

How does the PM chipbreaker affect machining?
The chipbreaker PM guides chip formation for typical turning tasks, improving evacuation and reducing the risk of entanglement in both external and internal turning operations.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the insert’s cylindrical hole with single-sided countersink is intended for standard clamping systems that accept this ISO variant.

What are the main dimensional characteristics to check before ordering?
Key dimensions include plate size (12 mm), plate thickness (4.76 mm), nose radius (1.2 mm) and clearance angle (7°); these determine fit and expected cutting performance.

Is this an indexable ISO-format insert and how does that help production?
Yes — the SCMT120412-PM is an ISO indexable insert; its standard format enables quick indexing and replacement, supporting predictable tool life and reduced downtime.
