TNMG 220404 AH6235 — Indexable turning insert for turning by Tungaloy

The TNMG 220404 AH6235 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for machining stainless steel and intermittent cut conditions.

• PVD-coated carbide AH6235 for tough work
• ISO TNMG220404 triangular insert form
• Double-sided chipbreaker for interrupted cuts
• Cylindrical hole, compatible with standard holders

Grade engineered for demanding stainless steel applications

The AH6235 grade is a PVD-coated carbide developed for enhanced toughness when machining stainless steel and other difficult-to-machine alloys. The coating improves wear resistance while the tougher substrate mitigates edge chipping under interrupted cuts. This combination delivers a consistent cutting edge life and predictable tool change intervals, which supports production planning and reduces unexpected stoppages. The specification is particularly suited to operations where edge stability is critical.

Geometry and ISO compatibility for predictable set-up

The triangular ISO form with code 220404 and a corner radius of 0.4 mm provides a balance between strength and finishing ability. The insert thickness of 4.76 mm, inscribed circle size 22 mm and the 60° included angle conform to standard ISO holder interfaces; the insert features a cylindrical hole for secure clamping and a double-sided chipbreaker offering two usable cutting edges. The listed free angle is 0°, indicating a neutral clearance geometry suited to many turning profiles. Compatibility with a particular holder depends on insert form, clearance, tolerance class, fastening method, size and thickness.

Operational gains: stable cutting, easier process control

Use of this indexable insert reduces regrinds and simplifies inventory management by offering a robust edge for interrupted cuts and unstable setups. The double-sided chipbreaker improves chip control and can reduce cycle time by lowering the need for manual chip clearing. For finishing or medium cuts the small corner radius helps maintain surface quality without sacrificing edge life. Selecting the appropriate chipbreaker and grade according to component material and machine stability will maximise throughput and tool life while ensuring consistent surface results.

FAQ

What materials is this insert optimised for?
The AH6235 grade is optimised for machining stainless steel and other alloys where toughness and resistance to chipping are required; it is suitable for interrupted cuts.

Which holder types are compatible with the insert?
Compatibility is determined by insert form, clearance, tolerance class, fastening method, size and thickness; the TNMG220404 form fits standard ISO TNMG external and internal turning holders designed for a 22 mm inscribed circle.

How many usable cutting edges does the insert provide?
The insert is double-sided with a chipbreaker on both faces, offering two indexed cutting edges per insert for efficient edge usage.

What benefits does the PVD coating deliver in practice?
The PVD coating on the AH6235 grade increases wear resistance and helps maintain edge integrity, extending service life under demanding conditions.

Is the insert suitable for finishing operations?
With a 0.4 mm corner radius and neutral geometry, the insert can achieve good surface quality in finishing passes while retaining sufficient strength for mixed operations.
