TNMG160404 AH120 indexable insert for turning — Tungaloy

The TNMG160404 AH120 is a triangular ISO indexable insert designed for external and internal turning, offering a wear- and chip-resistant grade for stable cutting and reproducible results.

• PVD-coated cemented carbide AH120
• ISO TNMG 160404 triangular insert
• 0.4 mm corner radius for fine finishes
• Double-sided with cylindrical hole

Consistent edge life for continuous production

The combination of a PVD-coated surface and cemented carbide substrate ensures a stable cutting edge that resists wear and chipping under typical turning loads. This results in fewer indexings and less downtime, supporting a steady production rhythm. The AH120 grade is formulated to balance toughness and hardness, providing process security when a sharp edge and repeatability are required.

Geometry that simplifies clamping and accuracy

The ISO TNMG 160404 triangular shape, a 60° included angle and a 0° relief clearance are optimised for reliable seating in standard holders. The insert’s cylindrical hole and specified 4.76 mm thickness provide secure clamping and repeatable positioning, which contributes to dimensional accuracy and reduces vibration in medium-stable set-ups. Correct holder selection enhances these geometric benefits and improves surface finish.

Fine edge and surface quality from a small corner radius

With a 0.4 mm corner radius the insert supports improved surface quality on external and internal profiles while maintaining controlled cutting forces. The modest radius is particularly effective where a fine finish is required without sacrificing tool life. When paired with the appropriate double-sided chipbreaker, this geometry helps produce consistent chip control and reduces the likelihood of built-up edge.

Grade and chip control tailored to turning tasks

The AH120 grade is a PVD-coated option optimised for wear resistance and reduced chipping during turning. The insert is suitable for a broad range of steels and common alloys when the correct chipbreaker and cutting parameters are selected. Choosing the right combination of grade, chipbreaker and machine stability converts material properties into measurable productivity gains and fewer interruptions.

FAQ

What materials can be machined with this insert? The AH120 PVD-coated cemented carbide insert is designed primarily for turning of steels and a broad range of common alloys when paired with the appropriate chipbreaker and cutting data; the TNMG160404 AH120 insert performs well where wear resistance and chip control are required.

How does the 0.4 mm corner radius affect surface finish? A 0.4 mm corner radius helps achieve finer surface finishes and controlled cutting forces; the combination of this radius with the AH120 grade reduces the risk of chipping while improving the finished part quality.

Is the insert compatible with standard ISO holders? Yes, the ISO TNMG 160404 geometry and cylindrical hole are made for compatibility with standard ISO external holders and boring bars, with secure clamping ensured by matching form, tolerance class and fastening method.

Can this insert be used on internal turning applications? The triangular form and double-sided design allow the insert to be used for both external and internal turning operations, provided machine rigidity and holder configuration are appropriate.

What information identifies this exact item when ordering? Use the designation TNMG160404 AH120, manufacturer article number 6814902 and SKU 6814902-Tungaloy to ensure the correct PVD-coated insert is supplied.
