TNMG 110408 AH6225 triangular turning insert for turning — Tungaloy

A TNMG 110408 AH6225 triangular indexable insert designed for reliable external and internal turning of stainless steels in medium machining conditions

• PVD-coated carbide, universal for stainless steel
• Sharp and stable cutting edge for medium cuts
• ISO triangular insert, 11 mm size
• Cylindrical hole, secure clamping fit

Stable, efficient cutting for stainless steels

The PVD-coated carbide grade provides a balance between sharpness and edge stability, making it suitable for machining stainless steels under varying operational conditions. Thanks to the PVD-coated surface, wear resistance is improved and flank wear is delayed, which helps maintain a consistent surface finish and extends tool life. The geometry focuses on delivering a sharp cutting edge while resisting chipping during interrupted cuts, so production runs remain predictable and tool-change intervals are minimised.

Reliable fit and secure clamping in ISO systems

The ISO-compliant triangular form and the cylindrical hole enable straightforward integration into common external holders and boring bars. The insert’s 4.76 mm thickness and defined 0° clearance are matching parameters that determine holder compatibility alongside tolerance class and fastening method. The double-sided chipbreaker layout offers reversible use to maximise economy; when mounted correctly, the insert achieves stable clamping and consistent chip control, reducing the need for repeated adjustments and improving process reliability.

Practical handling and consistent production results

The modest 0.8 mm corner radius provides a compromise between edge strength and dimensional accuracy, supporting medium-depth cuts with reduced vibration sensitivity. As a triangular indexable insert, it is reversible and therefore contributes to lower tooling inventory costs and shorter set-up times. The insert’s design and grade are optimised for a wide range of stainless steel turning tasks, delivering a dependable mix of productivity and surface quality while simplifying tool selection and stock management.

FAQ

What materials is this insert suitable for?
The TNMG110408 AH6225 insert is formulated for machining stainless steels, offering a balance of edge sharpness and wear resistance suitable for medium turning tasks.

How does the insert mount to standard holders?
Compatibility depends on form, clearance angle, tolerance class, fastening and thickness; the TNMG110408 features a cylindrical hole and ISO triangular form for secure clamping in appropriate holders.

Can the insert be used on both external and internal turning operations?
Yes, the geometry and double-sided chipbreaker make the insert suitable for both external and internal turning when combined with a matching holder and cutting parameters.

What does the 0.8 mm corner radius affect in machining?
The 0.8 mm corner radius provides increased edge strength and better vibration resistance, supporting stable medium-depth cuts while maintaining acceptable dimensional control.

Is the grade reversible and cost-efficient?
The triangular, double-sided design allows reversible indexing, which maximises the number of usable cutting edges and improves tooling economy for workshop stocks.
