TNMG220404 AH6225 — ISO turning insert for turning applications by Tungaloy

A TNMG220404 AH6225 indexable triangular turning insert engineered for medium cutting conditions and reliable stainless steel machining.

• ISO triangular insert TNMG220404
• PVD-coated carbide AH6225 grade
• Optimised for stainless steels
• Double-sided chipbreaker, cylindrical hole

Precision and reliable cutting for productive turning

The combination of a PVD-coated surface and a wear-resistant carbide substrate delivers a balanced edge that keeps cutting forces predictable and tool life stable. Designed for medium-depth cuts, this triangular insert with a 60° geometry produces consistent chip control and surface quality in rotational turning operations. The coated grade AH6225 is formulated to maintain a sharp, yet robust edge under varying conditions, reducing the need for frequent index changes and supporting uninterrupted production runs.

Clear compatibility and secure clamping for quick tool changes

Built to ISO dimensions, the triangular insert simplifies toolholder selection and changeover procedures. The specified form, clearance angle and tolerance class determine holder compatibility; the insert’s cylindrical hole and standard thickness allow straightforward seating and positive clamping in most ISO TNMG-compatible holders. Reduced set-up time and predictable fit translate into measurable process efficiency, particularly in batch production where repeatability and minimal adjustment are essential.

Material adaptability and chip control that reduce rework

This grade is optimised for machining stainless steels, offering a mix of wear resistance and edge stability that helps prevent built-up edge and excessive workhardening. The double-sided chipbreaker design aids consistent chip formation across a range of feeds, improving evacuation and lowering the risk of surface damage. For workshops processing a variety of stainless alloys, the insert provides a pragmatic balance between surface finish and productivity, making it suitable for both external and internal turning tasks.

Practical handling, cost-effectiveness and application advice

The insert’s triangular shape provides multiple indexing positions, increasing the number of usable edges per insert and improving cost-efficiency over time. With a corner radius of 0.4 mm and a plate thickness of 4.76 mm, it suits medium-accuracy turning where a controlled corner form is required. For optimum results, select an appropriate chipbreaker and cutting parameters that match workpiece clamping and machine rigidity; tailored feeds and speeds will extend life and reduce scrap rates, supporting a leaner machining process.

FAQ

What materials is this insert suitable for?
The TNMG220404 AH6225 insert is optimised for stainless steels, offering a balance between wear resistance and edge sharpness for consistent turning results.

How does the AH6225 grade affect performance?
The AH6225 grade provides a PVD-coated, wear-resistant surface that maintains a sharp cutting edge under medium machining conditions, which improves life and surface quality for turning tasks.

Which holder types are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class and plate thickness; the TNMG220404 is designed to fit standard ISO TNMG-compatible turning holders with a matching 60° seating.

How many cutting edges are available per insert?
The triangular geometry and reversible orientation provide multiple usable edges; the exact count depends on whether both sides are used and how the insert is indexed.

What chip control features does the insert provide?
A double-sided chipbreaker supports consistent chip formation across varied feeds, improving evacuation and helping to avoid surface damage during turning.
