RNMG 120400 AH120 turning insert by Tungaloy

RNMG120400-61 AH120 Tungaloy is an ISO‑standard turning indexable insert designed for external and internal turning, offering wear- and fracture-resistant performance in production environments.

• ISO‑standard RNMG form for easy replacement
• PVD-coated carbide AH120 for increased wear resistance
• Suitable for external and internal turning
• Cylindrical hole for secure clamping
• Sharp cutting edge with high process stability

Greater process stability through a wear-resistant grade

The combination of a PVD-coated surface and the AH120 carbide grade delivers consistent performance in turning operations where a sharp cutting edge and reliability are required. The coating reduces abrasive wear and helps maintain edge retention during extended cycles, which in turn supports predictable tool life and fewer interruptions to production. Explaining the coating briefly: PVD coating applies a thin, hard layer that enhances surface hardness without compromising core toughness, so the insert balances durability and fracture resistance.

Secure clamping and ISO compatibility cut setup time

Compatibility with holders is determined by form, clearance angle, tolerance class, attachment, size and thickness; the RNMG geometry and the cylindrical hole ensure repeatable seating and secure fastening. With a nominal plate size of 12 mm and a plate thickness of 4.76 mm, the insert fits standard ISO RNMG holders and minimises play that can affect surface finish and dimensional accuracy. Clear specifications reduce uncertainty during tool selection and speed up changeovers on the machine.

Versatile application coverage for routine and demanding turning

Designed for both external and internal turning, the insert supports a wide range of workpiece materials when the correct chipbreaker and grade are selected. The AH120 grade is formulated to be both wear‑ and fracture‑resistant, making it suited to pragmatic production scenarios where process safety is as important as cutting performance. For machining strategies that demand stability, matching the chipbreaker and insert grade to the workpiece and setup will deliver consistent surface quality and repeatable results.

FAQ

What materials is this insert suitable for? The RNMG120400-61 AH120 Tungaloy insert is designed for a broad range of materials when the correct chipbreaker and machining parameters are used; the AH120 grade emphasises wear and fracture resistance for stable turning.

How does the PVD coating improve performance? A PVD coating on the insert increases surface hardness and wear resistance, which helps the RNMG120400-61 maintain a sharp cutting edge and deliver consistent results over longer tool life.

Which holder features are required for proper compatibility? Compatibility requires a holder that matches the RNMG form, clearance angle (0°), tolerance class, attachment type, size (12 mm) and plate thickness (4.76 mm) to ensure secure clamping and repeatable positioning.

Is this insert suitable for both internal and external turning? Yes, the geometry and chipbreaker option make the insert appropriate for both external and internal turning operations provided the machining setup and stability are adequate.

How is chip control addressed with this insert? Chip control is achieved by selecting the chipbreaker style 61 together with the AH120 grade; this pairing helps produce predictable chips and supports process safety during turning.
