TNMG220412 AH6235 Tungaloy turning insert — triangular ISO insert, PVD-coated carbide, 60° main angle

TNMG220412 AH6235 Tungaloy is an ISO-standard triangular indexable insert designed for general external and internal turning, optimised for rostfreie Stähle and interrupted cutting conditions

• TNMG ISO triangular insert, 60° geometry
• PVD-coated carbide AH6235 for rostfreie Stähle
• 1.2 mm corner radius for increased insert strength
• Double-sided chipbreaker with cylindrical hole

Maximise tool life under demanding conditions

The combination of a PVD coating and tough carbide substrate in this grade provides a clear advantage when machining rostfreie Stähle or workpieces prone to built-up edge. The coated surface reduces friction and improves wear resistance, which in turn helps to maintain a sharp cutting edge for longer periods. For production environments where interrupted cuts occur, the 1.2 mm corner radius increases mechanical strength at the cutting edge and reduces the risk of chipping, resulting in fewer indexings and less tool change downtime. This leads to improved process stability and a better cost-per-component ratio.

Consistent chip formation and stable machining results

The double-sided chipbreaker geometry is engineered to control chip shape across a range of feeds and depths of cut. Controlled chip formation reduces the likelihood of entanglement and improves evacuation from the cutting zone, which supports uninterrupted runs and safer automated operations. Because the insert is ISO-standard, compatibility with a wide range of holders is given, provided form, clearance (free) angle, tolerance class, fastening and thickness match — this simplifies tool procurement and reduces inventory complexity in mixed-production shops.

Practical compatibility and application guidance

This insert is supplied with a cylindrical hole for secure clamping and a 4.76 mm plate thickness, features that support reliable fixation and repeatable seating in indexable holders. The triangular 60° shape offers three effective cutting edges per index, while the double-sided design doubles the usable livespan compared with single-sided alternatives. When selecting cutting data, favour moderate cutting speeds and proper coolant strategy for rostfreie Stähle to avoid built-up edge; the tougher grade is forgiving under less-than-ideal conditions but benefits from appropriate process parameters.

Why this grade suits mixed-production environments

Grade AH6235 is developed to strike a balance between toughness and wear resistance, making it particularly suitable for unstable cuts, short-chipping operations and varying material batches. In practice, this means fewer rejected parts due to edge failure and a steadier surface finish over the life of the insert. The insert’s design supports shops aiming for both productivity and reproducibility: reduced interruptions from insert damage and reliable dimensional stability support higher overall equipment effectiveness (OEE) in daily operation.

FAQ

What materials is this insert suited for?
The Tungaloy TNMG220412 AH6235 insert is formulated primarily for rostfreie Stähle and is able to cope with interrupted cuts and applications with increased risk of edge breakouts.

How many edges are available per insert?
The triangular, double-sided design provides three indexed positions per side and two usable sides, offering up to six effective cutting edges before disposal or regrinding.

Is the insert compatible with standard ISO holders?
Compatibility is determined by form, free angle, tolerance class, fastening, size and thickness; the insert follows ISO dimensions so it fits ISO-standard holders that match these parameters.

What benefits does the PVD coating deliver?
The PVD coating reduces friction and improves wear resistance, supporting longer edge life and more consistent surface finishes on challenging materials.

Can this insert be used for finishing operations?
Yes; with appropriate cutting parameters the grade and geometry provide stable cutting for both semi-finishing and finishing passes on suitable materials.
