TNMG220412 AH6235 TNMG indexable turning insert — PVD‑coated carbide, 1.2 mm radius — Tungaloy

The TNMG220412 AH6235 Tungaloy insert is an ISO‑standard turning insert engineered for external and internal turning, notably on stainless steel and in interrupted cutting situations.

• PVD‑coated carbide for enhanced tool life
• Double-sided chipbreaker for stable chip control
• 1.2 mm corner radius for edge strength
• ISO‑compliant triangular form with cylindrical hole

Improved process security through a tougher grade and coating

The combination of a PVD‑coated surface and a carbide substrate in this grade provides a balanced resistance to wear while maintaining toughness for transient loads. The AH6235 grade is formulated to resist chipping in intermittent cutting and is therefore suitable where surface integrity and repeatable edge life are critical. Using this insert reduces unexpected tool failures and contributes to steadier cycle times, which supports predictable production planning and cost control.

Fast, reliable clamping and straightforward compatibility checks

Designed to ISO dimensions, the insert's triangular form and cylindrical hole permit straightforward seating in matched holders; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. The 0° clearance angle and 22 mm size mean that clamping forces are transmitted efficiently and the 4.76 mm thickness contributes to stiffness at the cutting zone. These characteristics make tool changes and indexing quick, reducing machine downtime and supporting higher overall productivity.

Application guidance for turning stainless steels and interrupted cuts

This insert is optimised for turning of stainless steel and other materials prone to work hardening, where a 1.2 mm corner radius gives a robust cutting edge that tolerates occasional impact and prevents premature edge breakdown. The double-sided chipbreaker promotes controllable chip formation across a range of feeds and depths of cut; select a matching chipbreaker style and cutting data according to material and machine rigidity. For machining interrupted surfaces, the grade’s toughness helps avoid catastrophic edge failure, improving uptime and surface consistency.

FAQ

What materials is this insert best suited for?
The TNMG220412 AH6235 Tungaloy insert is formulated for machining stainless steel and other demanding alloys, especially where interrupted cutting or higher breakout risk is present.

How does the double-sided chipbreaker affect performance?
The double-sided chipbreaker provides improved chip control and allows additional indexing, which extends usable life before replacement or reconditioning is required.

Which holders are compatible with this ISO insert?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; the ISO‑compliant dimensions of the TNMG220412 make it compatible with matching TNMG holders of the correct specification.

What advantage does the 1.2 mm corner radius provide?
A 1.2 mm corner radius offers increased edge strength and tolerance to intermittent cutting, reducing the risk of chipping and improving edge life in interrupted or unstable cutting conditions.
