CNMG 120412 AH8005 Turning insert (ISO CNMG120412) by Tungaloy
The CNMG120412 AH8005 is an ISO-format rhombic turning insert designed for external and internal turning, offering a wear-resistant PVD-coated carbide grade for stable machining of heat-resistant alloys and hard materials.
- PVD-coated carbide grade AH8005
- ISO CNMG120412 rhombic insert
- Dual-sided chipbreaker for stable cuts
- 1.2 mm corner radius, 0° rake angle
Durable coating and grade for extended tool life
The PVD-coated AH8005 carbide blend combines a hard substrate with a thermally stable coating, delivering improved wear resistance under elevated temperatures typical of machining heat-resistant alloys. This formulation reduces flank and crater wear, which translates into longer tool life and fewer interruptions for insert changes. Explained plainly: the coating acts as a protective layer, slowing abrasive and adhesive wear so that machining runs remain consistent over longer cycles.
ISO conformity and secure mounting for predictable integration
Supplied in the ISO CNMG format, the insert conforms to established geometric standards that simplify matching with holders and boring bars. Compatibility is governed by form, clearance angle, tolerance class, fastening method, size and thickness; the CNMG120412 shape with a cylindrical hole allows secure clamping and repeatable positioning. Predictable interfacing reduces setup time and downtime, supporting steady production flow and easier tool inventory management.
Geometry optimised for surface quality and stable cutting
The combination of a dual-sided chipbreaker, 1.2 mm corner radius and 0° rake angle is tailored for controlled chip formation and reduced cutting forces in stable setups. The double-sided chipbreaker enables indexing to a fresh edge without immediate disposal, while the modest corner radius balances strength and surface integrity. As a result, the cutting insert contributes to a consistent surface finish and dependable dimensional results when used with appropriate feeds and speeds.
Practical system considerations and recommended use
The complete machining system comprises the insert, a matching externalholder or boring bar, shim or clamp sets and spare fastening screws. The CNMG geometry is suited to a broad range of turning tasks; selecting the correct chipbreaker and the AH8005 grade according to the workpiece material and machine stability yields the best results. For complex applications or mixed materials, consultation on holder geometry and cutting parameters helps to unlock the full potential of the insert.
