TNMG220412 AH6225 triangular indexable insert for turning, Tungaloy

A TNMG220412 AH6225 indexable insert designed for ISO‑compliant turning, optimised for medium machining of stainless steels with a stable cutting edge and reliable chip control

• ISO‑standard TNMG geometry
• PVD‑coated carbide grade AH6225
• Double‑sided chipbreaker
• Optimised for stainless steel turning

Reliable edge performance for variable stainless‑steel work

The combination of a PVD‑coated carbide substrate and the AH6225 grade provides a balance of edge sharpness and wear resistance that suits many machining scenarios. This inserts’ 1.2 mm corner radius and double‑sided chipbreaker are configured to produce controlled swarf and a consistent cutting line, which reduces process interruptions. The data sheet’s specification of a 0° clearance angle gives a neutral cutting geometry that performs well in stable setups and helps maintain a durable cutting edge during intermittent cutting or variable feed rates.

Designed for straightforward integration into ISO tool systems

The insert follows ISO‑compliant TNMG geometry and features a cylindrical clamping hole, making it compatible with a broad range of external holders and boring bars that accept this form. The 60° triangular shape enables three effective cutting edges per side and easy indexing to the next usable edge, while the 4.76 mm thickness ensures sufficient rigidity in the pocket under moderate to stable cutting forces. When assembling the tool system, match holder form, clearance, tolerance class and clamping hardware to achieve the expected repeatability and surface finish.

Economic machining with predictable results

Selecting a universal grade designed for rostfrei (stainless) materials helps to reduce tooling variants across a production cell. The insert’s wear characteristics and optimised chipbreaker lower setup time and part rework, contributing to improved spindle uptime and batch consistency. For medium cutting conditions and mixed‑material batches where turnaround and reliability matter, this format offers a pragmatic balance between tool life and surface quality while simplifying inventory through a common ISO geometry.

FAQ

Which materials is this insert best suited for?
The TNMG220412 AH6225 Tungaloy insert is optimised for machining stainless steels and performs well under varying conditions where a sharp, stable edge is required.

Is the insert indexable and how many edges are usable?
This triangular, double‑sided insert provides multiple usable edges; the TNMG form allows indexing to fresh cutting corners as edges wear.

What clamping and holder compatibility is required?
Compatibility depends on holder form, clearance angle, tolerance class and clamping method; the cylindrical hole and ISO geometry make the insert compatible with standard TNMG‑capable holders.

What cutting conditions suit this grade and geometry?
The AH6225 grade suits medium cutting conditions with an emphasis on stable chip control; moderate feeds and speeds with appropriate coolant yield consistent results.
