TNMG160404 AH6225 – ISO turning insert (triangle, 60°) by Tungaloy

TNMG160404 AH6225 is an ISO-format indexable turning insert for general external and internal turning applications, designed to deliver a stable cutting edge in changing conditions.

• TNMG triangular insert, 60° cutting geometry
• PVD-coated carbide grade AH6225
• 0.4 mm corner radius for balanced finish
• Double-sided chipbreaker with cylindrical hole

Reliable cutting for rostfreier Stahl with PVD-coated carbide

The PVD-coated carbide grade AH6225 is formulated as a universal grade for rostfreie Stähle, combining a keen edge with sufficient edge stability for medium cutting parameters. The coating improves wear resistance and heat protection, which extends the interval between indexings and reduces cycle interruptions. With a controlled balance between sharpness and toughness, this grade supports repeatable component tolerances while helping to maintain a consistent tool life in variable shop-floor conditions.

Fast integration into ISO tool systems reduces set-up time

As an ISO-standard insert in TNMG geometry, compatibility with tool holders is defined by the insert form, relief angle, tolerance class, fastening and plate thickness. The triangular shape with a 60° included angle and a cylindrical hole allows secure clamping and easy indexing on common external holders or boring bars. This standardisation means quicker changeovers and fewer holder variants in stock, supporting higher machine uptime and simpler logistics.

Predictable surface quality from precise geometry

A 0.4 mm corner radius provides a compromise between edge strength and surface finish: it reduces the risk of edge chipping while producing a machinable surface quality in medium feeds. The insert is double-sided, enabling two usable edges per side and economical use of the carbide body. The plate thickness of 4.76 mm contributes to rigidity under moderate cutting forces, supporting stable cutting for both external and internal turning tasks.

Practical application scope and system components

Intended primarily for turning operations, the insert performs best in medium-duty conditions where process stability and consistent chip control are required. The integrated chipbreaker geometry improves chip formation for rostfreier Stahl and eases chip evacuation; selection of the exact chipbreaker and grade should follow workpiece material, machining strategy and setup rigidity. Typical system components comprise the indexable insert, a matching external holder or boring bar, a locating shim/clamp set and replacement fixing screws.

FAQ

What materials is this insert suitable for?
The TNMG160404 AH6225 insert is specified for rostfreie Stähle and covers a broad range of stainless steel turning tasks under medium cutting conditions.

How does the AH6225 grade help with chip control?
The PVD-coated AH6225 grade, combined with the double-sided chipbreaker, promotes stable chip formation and evacuation when machining rostfreier Stahl with appropriate cutting parameters.

Can the insert be indexed on both sides?
Yes, the triangular TNMG design with a cylindrical hole is double-sided and provides multiple usable cutting edges for economical indexing.

What is the benefit of the 0.4 mm corner radius?
A 0.4 mm corner radius offers a balance between edge strength and surface finish, reducing edge chipping risk while delivering acceptable surface quality at medium feeds.

Is the insert compatible with standard ISO holders?
The TNMG160404 designation follows ISO norms; compatibility is determined by insert form, relief angle, tolerance class, fastening and thickness, and it fits matching ISO TNMG holders.
