TNMG 220404 T9225 TNMG turning insert — Tungaloy, CVD-coated carbide, 0.4 mm radius

The TNMG220404 T9225 indexable turning insert, made for turning, offers a robust universal grade tailored to medium and heavy steel machining with ISO compatibility and a triangular 60° geometry.

• CVD-coated carbide for high toughness
• 0.4 mm corner radius for fine turning
• ISO-standard triangular insert, 22 mm
• Cylindrical centre hole for secure clamping

Consistent cutting under varying engagement for steady productivity

The CVD-coated T9225 grade provides a balance of hardness and toughness that favours stable chip formation and extended tool life in fluctuating cut conditions. When facing occasional interruptions or changes in material engagement, the coated carbide substrate absorbs shock and resists premature edge failure, reducing downtime and tool changes. This results in fewer interrupted cycles and a more predictable production rhythm, which supports higher overall throughput with less rework.

Easy integration into ISO tool systems reduces setup time

Designed to the ISO series of indexable turning plates, the triangular insert with a 60° included angle and 22 mm nominal size integrates with standard external holders or boring bars. Compatibility is determined by shape, clearance angle, tolerance class, clamping and plate thickness; the 4.76 mm plate thickness and cylindrical hole facilitate secure fastening with common clamping sets and replacement screws. Clear identification of these parameters streamlines holder selection and shortens setup and changeover times on the shopfloor.

Robust edge geometry for repeatable surface quality

The 0.4 mm corner radius offers a controlled transition between roughing and finishing, delivering a consistent cut edge that reduces the need for downstream machining. Coupled with the double-sided chipbreaker, the geometry supports reliable chip control across a range of cutting depths, improving surface integrity and dimensional repeatability. The 0° clearance angle and CVD coating further protect the edge against flank wear, helping to maintain part tolerances over longer tool lives.

Economical machining through a universal, hard-wearing grade

The TNMG220404 T9225 insert brings together a universal cutting grade and proven geometry to lower cost per part by extending tool life and reducing indexing frequency. The combination of a resilient CVD-coated surface and a stable substrate means fewer insert changes in medium to heavy steel turning, making the component particularly suitable where production demands steady, repeatable results. For complete system reliability, pair the insert with matching holders and clamping kits to exploit its full potential.

FAQ

What materials is this insert best suited to?
The TNMG220404 T9225 insert is optimised for medium to heavy steel machining thanks to its CVD-coated T9225 grade and robust carbide substrate, offering reliable performance under variable cutting conditions.

How does the insert secure in standard holders?
The triangular plate features a cylindrical centre hole and a standard ISO form; secure clamping is achieved when matching holder geometry, tolerance class and plate thickness (4.76 mm) are observed.

Is this geometry suitable for interrupted cuts?
Yes — the T9225 grade and the insert’s toughness make it suitable for applications with occasional interruptions or variable engagement, improving resistance to chipping.

What surface finish can be expected with the 0.4 mm radius?
The 0.4 mm corner radius strikes a balance between finishing and robustness, delivering consistent surface quality while preserving edge stability across moderate feeds and depths of cut.
