CNMG 160612 AH8005 – Turning Insert (ISO CNMG160612, PVD-coated Carbide) by Tungaloy

The CNMG160612 AH8005 is an ISO‑standard rhombic turning insert designed for external and internal turning of heat‑resistant alloys and hard materials, offering wear resistance and process stability in demanding machining tasks

• ISO CNMG160612 format, rhombic 80° geometry
• PVD‑coated carbide AH8005 for wear resistance
• Double‑sided chipbreaker for stable cutting
• 16 mm size, 6.35 mm thickness, R1.2 corner

Predictable cutting performance through hardened grade and coating

The combination of a PVD‑coated surface and a wear‑resistant AH8005 carbide composition delivers reliable resistance to abrasion and thermal load. This results in more predictable tool life and fewer unexpected interruptions in production. For turning applications on heat‑resistant alloys and relatively hard workpieces, the treated cutting edge maintains form under steady cutting conditions, which supports consistent surface quality and reduces the need for frequent insert changes. The treated edge also assists in maintaining tolerance accuracy over longer runs.

Quick interchangeability and stable clamping for reduced downtime

Built to the ISO CNMG160612 format with a rhombic, 80° main cutting geometry and a cylindrical hole for secure fastening, the insert is compatible with standard CNMG holders when form, clearance angle and tolerance class match. The ISO standardisation supports straightforward replacement and inventory management, while the supplied geometry ensures a stable seating and minimal micro‑movement during cutting. The practical outcome is reduced setup time and improved repeatability across series production.

Better chip control and process security with a double‑sided chipbreaker

The integrated double‑sided chipbreaker promotes controlled chip formation across a range of feeds and depths of cut, lowering the likelihood of entangling or long, stringy chips that can harm the workpiece or tool. In combination with a stable machine setup, this feature enhances process reliability and helps to secure reproducible results in both roughing and finishing passes. Choosing the correct chipbreaker and grade according to the workpiece material and machining stability further optimises productivity.

Geometry and dimensions that support versatile turning tasks

With a 16 mm inscribed circle, 6.35 mm thickness and an R1.2 corner radius, the insert suits operations where a balance between edge strength and accuracy is required. The 0° clearance angle and rhombic shape make it suitable for a variety of external and internal profiles, while the robust carbide substrate provides the rigidity necessary for interrupted cuts in stable setups. These dimensions are especially useful where a compromise between fine surface finish and economical material removal is sought.

FAQ

How well does this insert handle heat‑resistant alloys?
The CNMG160612 AH8005 grade, with its PVD‑coating and wear‑resistant carbide composition, is engineered to withstand the thermal and abrasive stresses typical of heat‑resistant alloys, offering extended edge life under stable cutting conditions.

Is the geometry compatible with standard CNMG holders?
Yes—being ISO CNMG160612 format with a rhombic 80° geometry and a cylindrical hole, the insert is compatible with holders designed for CNMG inserts provided that form, free angle and tolerance class match the holder specifications.

Which workpiece materials are recommended for this grade?
The AH8005 grade is optimised for heat‑resistant alloys and harder materials; it also performs well on a broad range of steels when machining conditions and machine stability are appropriate.

What benefit does the double‑sided chipbreaker provide?
The double‑sided chipbreaker ensures controlled chip formation, improving process security and surface finish while reducing the risk of chip interference during both roughing and finishing operations.

How should one choose the correct insert for a specific turning task?
Select the insert based on workpiece material, machine rigidity and the stability of the setup; the CNMG160612 AH8005 is suitable where wear resistance and thermal stability are priorities—Metav Werkzeuge can advise on matching holder geometry and cutting data.
