TNMG 110408 AH6225 Turning Insert – Tungaloy, PVD-coated carbide, R0.8

TNMG 110408 AH6225 is an ISO-style indexable insert designed for external and internal turning, optimised for rostfreien Stahl in medium-duty and variable conditions

• PVD-coated carbide grade AH6225
• Sharp yet stable cutting edge
• Suitable for rostfreien Stahl machining
• Triangular insert, corner radius R0.8

Consistent medium-duty turning with reliable edge life

The TNMG indexable insert delivers predictable performance where mixed batch sizes and varying workpiece conditions are common. The AH6225 grade combines a hard, wear-resistant substrate with a PVD-coated surface, which reduces built-up edge and extends tool life during intermittent feeds. For production environments that demand repeatability, this indexable solution maintains cutting edge integrity over successive indexings, reducing spindle downtime and supporting a steady throughput.

Seamless integration into ISO turning systems

As an ISO-standard turning insert, compatibility is determined by shape, clearance, tolerance class, fastening and thickness. The triangular geometry with a 60° included angle and 0.8 mm corner radius offers a balance between strength and edge acuity. The insert thickness is 4.76 mm, and the design incorporates a cylindrical hole for secure clamping. These specifications make the component straightforward to match with common external holders or boring bars that accept TNMG-type inserts, simplifying tool inventory and setup.

Improved chip control and process stability

Equipped with a double-sided chipbreaker, this insert promotes consistent chip formation across a range of feeds, which supports safer machining and easier evacuation in turning operations. The PVD coating enhances thermal resistance and adhesion, while the carbide body provides the necessary toughness for variable cutting forces. For rostfreien Stahl, where work-hardening and adhesion are concerns, the combination of sharp geometry and coating reduces friction and helps maintain surface quality during finishing and medium turning.

Practical handling and production benefits

The triangular, double-sided design enables multiple indexings, extending the usable lifetime per insert and improving cost efficiency in the toolroom. Identification is straightforward via the ISO designation and manufacturer SKU. Routine changes are quick thanks to the standardised hole and fastening interface; replacements and spare screws are part of a typical tool system kit. If process optimisation or grade selection is required for specific rostfreien Stahl alloys, expert advice is available to ensure the Tungaloy grade is applied where it brings the best economy and surface finish.

FAQ

How is this insert best used for rostfreien Stahl?
The TNMG 110408 AH6225 insert from Tungaloy is formulated for rostfreien Stahl turning with a sharp, stable cutting edge and PVD coating to reduce adhesion and maintain surface quality.

Is the insert compatible with standard TNMG holders?
Yes. The TNMG110408 designation and cylindrical hole follow ISO conventions, enabling fitment in holders and boring bars designed for TNMG inserts.

How many indexings are available on this insert?
The triangular, double-sided design allows multiple indexings; the double-sided chipbreaker increases the number of usable edges before disposal.

What does the AH6225 grade provide compared with uncoated carbide?
AH6225 combines a wear-resistant substrate with a PVD coating to improve thermal resistance and reduce built-up edge during variable and medium machining.

What are the geometric details to check before purchase?
Confirm corner radius (0.8 mm), plate thickness (4.76 mm), included angle (60°) and hole style (cylindrical) to ensure holder compatibility.
