CNMG 190608 AH120 ISO indexable turning insert, PVD-coated carbide by Tungaloy

The CNMG190608-TM AH120 is an ISO rhombic indexable insert for turning, designed for external and internal operations where a sharp cutting edge and process security are required.

• PVD-coated, wear-resistant AH120 grade
• ISO rhombic CNMG, 19 mm size
• 0.8 mm nose radius for precise finishes
• Cylindrical hole for secure clamping

Consistent cutting for demanding turning tasks

The PVD-coated AH120 grade delivers a balance of wear resistance and edge toughness that supports stable metalcutting across mixed workloads. As a PVD-coated carbide insert with a TM chipbreaker, the component reduces flank wear while maintaining a sharp cutting edge, which helps to prolong insert life and keep cycle times predictable. In practice, this means fewer interruptions for tool changes and more consistent part quality during series production.

Compatibility and secure mounting explained

Compatibility with a toolholder depends on the insert form, relief angle (0°), tolerance class, fastening method, size and thickness. The rhombic CNMG form with an 80° included angle and a cylindrical hole provides firm, repeatable clamping in matched CNMG holders or boring bars. Choosing a holder that matches the 19 mm inscribed circle and 6.35 mm thickness ensures correct seat contact and torque transmission, which is essential for process stability during heavy cuts or interrupted turning.

Precision geometry that supports surface finish

A 0.8 mm nose radius produces a fine balance between strength and finish: it is large enough to resist local chipping yet small enough to achieve tight dimensional control on turned parts. The insert geometry, combined with the TM chipbreaker, helps to form manageable chips and reduces the risk of rubbing or built-up edge, which in turn supports repeatable surface roughness and dimensional conformity across batches.

Grade and chipbreaker selection for specific jobs

The AH120 grade is formulated for applications where both edge sharpness and process reliability are required. The TM chipbreaker suits general-purpose turning and enhances chip control in a wide range of materials; for optimised performance, match the chipbreaker and grade to the workpiece material and machine stability. This targeted selection reduces tool consumption and often improves overall machining economy.

FAQ

What applications are suitable for this insert?
The CNMG190608-TM AH120 Tungaloy insert is intended for external and internal turning operations where a sharp cutting edge and process security are needed; choose the chipbreaker and grade according to the workpiece material and machining stability.

How is the insert secured in the holder?
The insert features a cylindrical hole and must be used with a compatible CNMG holder; compatibility depends on form, relief angle, tolerance class, fastening method, size (19 mm) and thickness (6.35 mm).

What does the AH120 grade and PVD coating provide?
The AH120 designation indicates a PVD-coated carbide grade designed for wear resistance and resistance to chipping, supporting longer tool life and consistent cutting performance in turning.

When is the TM chipbreaker recommended?
The TM chipbreaker is suitable for general turning tasks that require reliable chip control and stable cutting conditions; it helps to produce continuous, manageable chips and supports consistent surface finish.

How do geometry and radius affect results on the workpiece?
The 80° included angle and 0.8 mm nose radius balance strength and precision: the geometry resists edge failure while allowing good dimensional control and surface quality in routine turning operations.
