TNMG220404 AH6225 turning insert, triangular ISO turning insert – Tungaloy

The TNMG220404 AH6225 is an ISO‑standard triangular turning insert designed for external and internal turning, offering a balanced cutting edge for medium‑duty machining of rostfreiem Stahl.

• ISO‑standard triangular insert TNMG 220404
• PVD-coated AH6225 grade for rostfreiem Stahl
• 0.4 mm corner radius for precision finishes
• Double-sided chipbreaker; cylindrical mounting hole

Consistent cutting performance for rostfreiem Stahl

The insert’s PVD-coated surface and the AH6225 grade deliver a combination of wear resistance and edge sharpness that suits variable shop conditions. For rostfreiem Stahl the coating reduces built‑up edge and improves thermal stability, which results in more consistent part tolerances and a lower scrap rate. The design aims to provide a sharp, stable cutting edge that maintains dimension and surface quality over longer tool life, reducing tool change frequency and supporting predictable cycle times.

Precision geometry and ISO compatibility for fast set-up

Built to ISO specifications as a TNMG type, the geometry ensures straightforward compatibility with common external holders and boring bars when the form, clearance angle, tolerance class, fastening method, size and thickness match. The 0.4 mm corner radius balances strength and finish capability: it supports small‑step finishing without compromising edge robustness. The triangular shape with a cylindrical mounting hole enables secure clamping and repeatable positioning, simplifying tool changeovers and minimising set‑up time on the shop floor.

Robustness and economic machining for medium‑duty turning

Made of premium carbide and finished with a durable PVD coating, the insert is intended for productive turning where stable chip control and repeatable performance matter. The double-sided chipbreaker provides two usable cutting edges per side, effectively increasing the number of operations per insert and improving cost per cutting edge. As an ISO‑standard turning component, it supports both external and internal turning strategies and is suitable where a reliable, general‑purpose insert is required for rostfreiem Stahl in varying conditions.

FAQ

Which materials is this insert suitable for?
The TNMG220404 AH6225 insert is specified for rostfreiem Stahl and performs well in medium‑duty turning where a sharp, stable edge is required.

What does the AH6225 grade indicate?
AH6225 denotes a PVD‑coated carbide grade engineered for a balance of wear resistance and edge sharpness, aimed at broad rostfreiem Stahl applications.

How is the insert clamped in a holder?
The triangular insert uses a cylindrical mounting hole and is clamped with an appropriate TNMG‑compatible holder; compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness.

How many usable edges does the insert provide?
With its double‑sided chipbreaker and triangular form, the insert offers multiple usable cutting edges per index, increasing economy and reducing downtime.

Is this insert suitable for internal turning?
Yes; the TNMG220404 geometry and chip control features are suitable for both external and internal turning operations when paired with the correct holder and cutting parameters.
