TNMG220412 AH6225 Tungaloy indexable insert — turning, 60° triangular, PVD-coated carbide

A TNMG220412 AH6225 indexable turning insert engineered for stable cutting performance in rostfreier Stahl and general turning applications, featuring a 60° triangular geometry and a robust 1.2 mm corner radius.

• PVD-coated universal carbide AH6225
• 60° triangular insert for versatile turning
• 1.2 mm corner radius for robust edge
• Double-sided chipbreaker with cylindrical hole

Longer tool life and consistent performance in rostfreier Stahl turning

The PVD-coated AH6225 grade is formulated to combine a sharp cutting edge with structural stability under medium cutting conditions. The carbide substrate with its wear-resistant coating reduces adhesion and built-up edge formation when machining rostfreier Stahl, which improves tool life and keeps process windows predictable. For production environments where repeatability and reduced tool changes matter, this combination translates into fewer interruptions, more consistent surface finishes and lower overall machining costs per component.

ISO-compliant geometry for fast integration into existing tool systems

Designed to the ISO indexable insert system, the triangular format with a 60° included angle and 0° clearance is compatible with a wide range of external holders and boring bars when matched by form, tolerance class, fastening and size. The insert is double-sided and features a cylindrical hole, enabling simple indexing and secure clamping. The standardised dimensions—22 mm across the insert, a thickness of 4.76 mm and a 1.2 mm corner radius—ensure predictable interchangeability between toolholders and spare inserts, reducing setup time and simplifying inventory management.

Stable chip control and productive turning with reliable edge security

A well-defined chipbreaker on both sides supports efficient chip formation and evacuation during turning operations, particularly in variable cutting conditions. The insert’s geometry and grade are balanced to resist edge chipping while maintaining cutting sharpness; the 1.2 mm corner radius adds robustness for interrupted cuts and semi-finish operations. Selecting the correct chipbreaker and matching the AH6225 grade to the workpiece and cutting parameters helps to increase process stability, lower scrap rates and maintain consistent part tolerances in batch production.

FAQ

What materials is this insert suitable for? This insert is intended primarily for rostfreier Stahl; the TNMG220412 AH6225 grade is a universal PVD-coated carbide designed for stainless applications and related steels.

How is the insert mounted and indexed? The insert has a cylindrical hole and a standard ISO triangular form; it is double-sided, enabling indexing by rotating or flipping the insert in a compatible holder.

What are the key geometric specifications to check for holder compatibility? Confirm the insert size (22 mm), thickness (4.76 mm), included angle (60°) and the 220412 designation to ensure the holder accepts the TNMG220412 AH6225 insert.

Which chipbreaker should be chosen for finishing versus medium machining? The double-sided chipbreaker design supports a range of conditions; pairing the chipbreaker style with the intended cut depth and feed will optimise chip control and surface finish for the chosen operation.

Is this insert suitable for interrupted cuts or semi-finish operations? Yes, the 1.2 mm corner radius and the AH6225 grade provide added edge strength for interrupted cuts and semi-finish turning, improving resistance to chipping.
