CNMG 160616 AH905 – Turning insert by Tungaloy (PVD‑coated, rhombic, 80°)

CNMG 160616 AH905 is an ISO‑standard rhombic turning insert intended for external and internal turning operations, offering a sharp cutting edge and high process security with PVD‑coated cemented carbide.

• ISO 160616 rhombic turning insert
• PVD-coated cemented carbide grade AH905
• 80° lead angle, 1.6 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Durable, PVD‑coated carbide for stable production

The PVD coating on this cemented‑carbide grade delivers a balanced combination of wear resistance and edge integrity that suits demanding turning operations. By limiting flank and crater wear, the coating extends the usable life of the cutting edge while maintaining a sharp cutting geometry for predictable surface finish. The selected carbide matrix supports thermal stability and toughness, which reduces the risk of premature edge failure under interrupted cuts. These technical properties translate into fewer tool changes and more consistent cycle times on both batch and continuous production.

Precision geometry that fits ISO tool systems

The rhombic shape with an 80° lead angle and a 1.6 mm corner radius provides a versatile geometry for general turning tasks where a defined cutting line and strength at the corner are required. The insert thickness of 6.35 mm and the ISO designation 160616 ensure compatibility with standard ISO holders; the insert is supplied with a cylindrical hole for secure clamping and correct axial location. The double‑sided design permits indexable use, doubling the number of effective cutting edges per insert and improving cost efficiency per cutting edge. Specified tolerances for form, relief and fixing must be considered when pairing the insert with a holder to guarantee repeatable clamping and performance.

Chip control and process security for reliable turning

A double-sided chipbreaker optimises chip formation for a broad range of cutting parameters and workpiece materials commonly encountered in turning. The AH905 grade is described as wear‑ and chipping‑resistant, making it particularly suitable where a sharp edge and high process security are required—for example, finishing and medium‑duty roughing in steels and similar materials. Stable chip control reduces rework and downtime and improves operator safety. For best results, match feed rates and depth of cut to the insert geometry and choose the holder rigidity to suit the intended operation; correct coolant application will further enhance edge life and surface quality.

FAQ

What materials is this insert suitable for? The CNMG 160616 AH905 turning insert, with its PVD‑coated cemented‑carbide grade, is designed for general turning applications and performs well in a wide range of common steels and similar materials where a sharp edge and process security are required.

Can the insert be indexed and reused? Yes, the insert is double‑sided and indexable; the CNMG geometry allows multiple edges to be used by repositioning the plate, which improves cost efficiency per edge.

How does the corner radius affect cut quality? A 1.6 mm corner radius increases edge strength and supports better surface finish in semi‑finishing and finishing operations, offering a compromise between robustness and the required cutting force.

Is the CNMG 160616 compatible with standard ISO holders? The insert carries the ISO designation 160616 and is intended for use with ISO‑compatible holders that match the plate form, size, thickness and hole style; correct holder selection ensures repeatable clamping and tool performance.

What benefits does the AH905 grade provide in turning? The AH905 PVD‑coated grade delivers wear‑resistance and resistance to chipping, combining a sharp initial edge with reliable life under variable cutting conditions, which supports consistent productivity.
