TNMG 220404 T9225 ISO turning insert, 0° clearance, triangular, by Tungaloy

A TNMG 220404 T9225 insert designed for medium to heavy turning applications, offering a durable CVD‑coated carbide grade and a double‑sided chipbreaker for economical indexable performance

• CVD-coated carbide grade T9225
• Suitable for medium to heavy steel turning
• Triangular TNMG 22 mm, 0° clearance
• Double-sided chipbreaker, with hole

Consistent cutting performance for medium to heavy steel

The CVD‑coated T9225 grade combines wear resistance with increased toughness, making it suitable for interrupted cuts and variable engagement conditions common in steel turning. A CVD coating enhances surface hardness and thermal stability; this reduces flank wear and preserves cutting edge integrity under higher loads. For production operations where repeatable tool life and predictable insert behaviour are priorities, the combination of CVD‑coated surface and robust carbide substrate supports longer intervals between indexing and replacement, while maintaining dimensional consistency on finished components. The ISO geometry also simplifies tool selection in mixed fleets.

Stable geometry and straightforward holder compatibility

The insert follows the ISO designation TNMG220404, with a triangular form, an inscribed size of 22 mm, corner radius 0.4 mm and a plate thickness of 4.76 mm. The included angle is 60° and the clearance angle is 0°; the insert is supplied with a cylindrical hole for secure fixing. Compatibility with external holders or boring bars is determined by the insert form, clearance, tolerance class, fastening method, size and thickness. Understanding these parameters enables correct pairing with an appropriate clamping set and replacement screws, avoiding mismatches that affect run‑out and surface finish. Clear geometry also aids programming and fixture repeatability.

Economic handling and system integration in the workshop

As a double‑sided, indexable insert the part offers two cutting edges per orientation, lowering per‑edge cost and simplifying stock management. The chipbreaker design suits a range of steel cutting tasks and assists in controlled chip formation, which reduces stoppages and improves operator safety. Integration into a turning system requires a matched external holder, the appropriate clamping set and spare screws; having these configured ensures fast changeover and minimised downtime. The insert’s properties support efficient production cycles and make it a practical choice for jobbing and series shops seeking stable tool life and straightforward handling under varying cutting conditions.

FAQ

Which materials are suitable for this insert?
The Tungaloy TNMG220404 T9225 insert is designed primarily for medium to heavy steel machining; the CVD‑coated T9225 grade provides the toughness and wear resistance needed for such applications.

How to ensure compatibility with a toolholder?
Compatibility depends on insert form, clearance, tolerance class, fastening method, size and thickness; match these parameters to the chosen holder and clamping set to ensure correct fit and repeatable performance with the TNMG form.

Is the insert indexable and reversible?
Yes, the insert is double‑sided and indexable, offering multiple cutting edges per insert for economical edge utilisation and simplified changeover.

What does the 0° clearance mean in practice?
A 0° clearance indicates the specified free or relief angle of the insert; correct holder geometry and setup must accommodate this to achieve the intended cutting conditions and surface finish.

Which accessory parts are typically required for use?
A compatible external holder or boring bar, a matching clamping set/underlay and appropriate replacement screws are required to mount the TNMG insert securely and to maintain process stability.
