CNMG190612 AH120 Turning Insert, PVD-coated Carbide — Tungaloy

CNMG190612 AH120 is an ISO indexable turning insert designed for precision external and internal turning where a sharp cutting edge and process security are required.

• PVD-coated grade AH120 for edge stability
• Rhombic CNMG form with 80° included angle
• 1.2 mm corner radius for balanced edge strength
• Double-sided insert with cylindrical hole

Consistent cutting performance for secure production

The ISO series of indexable turning inserts offers a dependable basis for machining where stability and repeatable performance matter. The PVD-coated carbide of this insert provides enhanced wear resistance and improved thermal stability, making it suitable where a consistently sharp edge is required. The AH120 grade is formulated for resistance to both abrasive wear and edge chipping, delivering process security during continuous turning tasks. Using a grade with these properties reduces unscheduled tool changes and supports a steady production flow.

Geometry and compatibility explained for easy selection

The insert follows the ISO designation CNMG190612 with a rhombic plate geometry and an 80° geometry, giving a versatile approach angle for a range of turning operations. A 1.2 mm corner radius balances edge strength and surface finish, while the 6.35 mm thickness and 19 mm size support stable clamping in standard external holders and boring bars. The insert is double-sided and features a cylindrical hole for secure mounting. Compatibility with a specific holder depends on shape, clearance angle, tolerance class, fastening method, size and thickness; the complete system comprises the insert, the matching external holder or boring bar, the shim/clamp set and replacement screws.

Practical shop-floor benefits and economical use

Using a rhombic ISO insert with a sharp, coated cutting edge allows productive turning with predictable results: fewer interruptions, consistent surface quality and effective chip control when the appropriate chipbreaker is chosen. The double-sided design increases usable life per index and lowers tooling cost per component, while the PVD-coated surface maintains edge integrity under varying speeds and feeds. For operations that demand a combination of sharpness and reliability, this insert supports high process uptime and simplifies inventory through ISO conformity.

FAQ

What types of turning operations suit this insert?
This insert is intended for external and internal turning operations; the CNMG190612 AH120 element is designed where a sharp cutting edge and process security are required.

How does the AH120 grade affect tool life?
The AH120 grade with its PVD-coated carbide construction improves resistance to abrasive wear and edge chipping, which contributes to longer, more predictable tool life for turning tasks.

What are the key geometric parameters to check for holder compatibility?
Check the insert form, clearance angle (0°), tolerance class, fastening type, plate size (19 mm) and thickness (6.35 mm) to ensure compatibility with the intended holder or boring bar.

Is the insert indexed on both sides?
Yes, the insert is double-sided, which increases the number of usable cutting edges and improves cost-efficiency per index.

Which chipbreaker should be chosen?
Select a chipbreaker that matches the workpiece material, the machining strategy and the required surface finish; the CNMG190612 AH120 insert performs best when the chipbreaker and grade are matched to the application.
