TNMG 220404 AH120 turning insert by Tungaloy — PVD-coated carbide, 60°

The TNMG220404 AH120 is an ISO-standard triangular indexable insert for external and internal turning, designed to provide a sharp cutting edge and reliable process security in a range of machining scenarios.

• ISO TNMG 220404 triangular turning insert
• PVD-coated carbide grade AH120 for wear resistance
• 60° geometry with 0.4 mm corner radius
• Double-sided chipbreaker and cylindrical hole

Productive cutting performance with sustained edge life

The PVD-coated AH120 grade is a wear- and fracture-resistant carbide that prioritises a durable, sharp cutting edge for demanding turning tasks. Combined with the 60° tool geometry and triangular form, the insert provides multiple usable edges per index, improving productivity and reducing tool-change frequency. The design supports steady metal removal rates while maintaining surface quality, so machining cycles remain predictable and efficient.

Secure clamping and reliable chip control for consistent results

Clamping is reinforced by the central cylindrical hole, which ensures exact seating and repeatable positioning in compatible ISO holders. The double-sided chipbreaker promotes controlled chip formation across a range of cutting conditions, lowering the risk of built-up edge and stabilising process behaviour. With a thickness of 4.76 mm and precise tolerances, the insert suits robust set-ups where vibration damping and repeatability matter for part accuracy.

Practical selection guidance to match material and stability needs

For external and internal turning, the choice of chipbreaker and grade should reflect the workpiece material, machine rigidity and desired surface finish. The TNMG220404 AH120 insert is particularly useful where a sharp edge and process reliability are required; its balanced properties make it adaptable across many steels and alloy applications. Selecting the correct chipbreaker and clamping arrangement will extend tool life and ensure consistent component quality.

FAQ

What materials is this insert suited for? The TNMG220404 AH120 insert is specified for turning applications where a sharp, wear-resistant edge is required; the AH120 grade and PVD coating make it suitable for a broad range of steels and alloyed materials when combined with an appropriate chipbreaker.

How does the 60° geometry affect cutting performance? A 60° cutting geometry offers a balance between strength and accessibility in turning operations; the TNMG220404’s geometry provides stable cutting for external and internal work while delivering good surface finish when mounted in a suitable ISO holder.

What does the double-sided chipbreaker provide? The double-sided chipbreaker on this indexable insert supports controlled chip formation on both usable faces, improving process stability and reducing the likelihood of chip-related interruptions during turning.

Is the insert compatible with standard ISO holders? Compatibility is governed by insert shape, free rake angle, tolerance class, fastening method, size and thickness; the TNMG220404 adheres to ISO dimensions and is intended for use with corresponding ISO standard holders.

How many usable cutting edges does the insert offer? The triangular shape of the TNMG220404 provides multiple indexable cutting edges; exact usable edges depend on the chosen index method and whether both sides are utilised with the double-sided chipbreaker.
