TNMG 220408 AH6225 Turning Insert — Tungaloy

The TNMG220408 AH6225 is an ISO-standard triangular indexable insert for turning, designed to deliver a sharp yet resilient cutting edge in general stainless-steel applications.

• ISO-standard triangular insert TNMG220408
• PVD-coated carbide grade AH6225
• Designed for stainless steels, robust cutting edge
• Double-sided chipbreaker with cylindrical hole

Consistent cutting performance for stainless steels

The insert offers a PVD-coated cemented carbide composition (grade AH6225) engineered for medium‑duty turning of stainless steels. The coating stabilises the cutting edge under variable cutting conditions, reducing built‑up edge and increasing process reliability. With a sharp cutting edge geometry and a corner radius 0.8 mm, the tool favours good surface quality while maintaining the robustness required for interrupted cuts. For shops seeking predictable material removal rates, the specification balances edge life with surface finish.

Compatibility and secure clamping to simplify tool setup

As an ISO-standard indexable insert in TNMG format, compatibility with standard TNMG holders is defined by form, clearance angle, tolerance class, clamping arrangement, size and thickness. The insert is triangular with a cylindrical hole and is double-sided, enabling economical index changes and reducing inventory. The 0° clearance angle and the insert’s 60° included angle ensure straightforward seating in designated TNMG pockets, simplifying tool setup and repeatability across toolholders and machines.

Productivity gains through reliable chip control and process stability

Built for steady chip formation, the double-sided chipbreaker promotes controlled evacuation and reduces the risk of entanglement in multi-pass operations. The combination of the AH6225 grade and the chipbreaker design supports consistent tool life and machining quality, which contributes to fewer interruptions and predictable batch throughput. In short runs or mixed batches where stainless steels vary, the insert provides an efficient compromise between edge sharpness and wear resistance, helping to lower overall machining costs per part.

FAQ

What materials is this insert suited for?
The TNMG220408 AH6225 insert is specified for stainless steels and selected general turning tasks where a balance of sharpness and edge stability is required.

How is the insert mounted and indexed?
The triangular, double‑sided design with a cylindrical hole allows mounting in standard TNMG pockets; the insert can be indexed to use both cutting edges.

What benefits does the AH6225 grade provide?
Grade AH6225 combines a PVD coating with a carbide substrate to improve wear resistance and reduce built‑up edge during variable stainless‑steel machining.

Is the geometry compatible with standard TNMG holders?
Yes, the ISO designation and the 60° included angle make the insert compatible with holders designed for TNMG220408 inserts, subject to matching tolerance and clamping style.

What feature helps with chip control in this insert?
The integrated double‑sided chipbreaker promotes controlled chip formation and evacuation, aiding productivity and surface finish.
