TNMG 160404 T9225 – Turning insert (ISO, Tungaloy)

The TNMG160404 T9225 is an indexable turning insert designed for medium to heavy steel machining; its triangular ISO form and CVD-coated cemented carbide construction provide both toughness and wear resistance

• CVD-coated cemented carbide for robustness
• ISO TNMG 160404 geometry, 60° cutting angle
• 0.4 mm corner radius for versatile turning
• Double-sided chipbreaker with cylindrical hole

Maximised metal removal with consistent edge life

The combination of CVD-coated surface and cemented carbide substrate delivers a balance of wear resistance and toughness that supports extended running times under varying cutting conditions. CVD coating (chemical vapour deposition) forms a hard, wear-resistant layer that reduces flank and crater wear while the substrate maintains fracture resistance. This results in more reproducible tool life and fewer unscheduled insert changes, improving overall machining throughput and lowering unit costs.

Easy integration into standard ISO tool systems

Thanks to the ISO-compliant triangular form and the cylindrical hole for secure fastening, the insert is straightforward to mount in a wide range of external holders and boring bars. The indexable design and double-sided chipbreaker mean multiple cutting edges are available before replacement is required, which minimises downtime. Compatibility with the clamping system is governed by insert form, relief angle and tolerance class; selecting the correct holder and correct fastening hardware ensures reliable seating and repeatable positional accuracy.

Grade selection for interrupted and heavy cuts

The T9225 grade is formulated as a robust universal solution for varying engagement conditions and slightly interrupted cuts, offering good toughness for medium to heavy steel machining. The double-sided chipbreaker promotes stable chip control across a range of feeds and depths of cut, reducing the risk of built-up edge and improving surface finish. Choosing this grade supports a broad material coverage while preserving cutting-edge integrity where conditions fluctuate.

Precision geometry that enhances surface finish and process security

The 60° cutting angle combined with a 0.4 mm corner radius and a 4.76 mm plate thickness provides a compromise between edge strength and form accuracy that favours consistent workpiece quality. The triangular shape yields three indexable edges per side, while the double-sided configuration increases the number of usable edges overall, offering cost efficiency. For optimal results, match the chipbreaker and grade to the workpiece material and machine rigidity to benefit from predictable chip flow and reduced rework.

FAQ

What materials is this insert suitable for?
The TNMG160404 Tungaloy insert (T9225 grade) is optimised for medium to heavy steel machining and performs well under varying engagement conditions.

Can the insert handle interrupted cuts?
Yes, the T9225 grade is designed for robustness and extra toughness, making the TNMG160404 suitable for slightly interrupted cuts and fluctuating cutting forces.

How is the insert mounted in a holder?
The triangular ISO form and cylindrical hole allow secure fastening in compatible external holders and boring bars; correct holder selection is essential for repeatable positioning.

How many usable edges does the insert provide?
The triangular, double-sided design offers multiple indexable edges—each indexing operation presents a fresh cutting edge, extending service life compared with single-sided inserts.

What does the CVD coating do for performance?
The CVD coating on the cemented carbide substrate increases wear resistance, reduces flank and crater wear, and supports consistent edge life in demanding steel machining tasks.
