SNMG 120404 T9225 Turning Insert — Tungaloy, CVD-coated Carbide

The SNMG 120404 T9225 is an ISO square indexable insert for external and internal turning, engineered for stable cutting under varying engagement and slightly interrupted cuts.

• CVD-coated carbide for robust performance
• Universal T9225 grade for medium–heavy steel
• 90° square geometry, 0.4 mm corner radius
• Double-sided chipbreaker with cylindrical hole

Stable performance in demanding turning operations

The combination of a CVD-coated surface and a wear-resistant carbide substrate results in reliable tool life and consistent surface finish when machining steel. The T9225 grade is specified for medium to heavy cutting conditions and for applications where changing entry and exit conditions demand greater toughness. The insert’s heat-resistant coating reduces flank wear and adhesion, which leads to fewer interruptions for inspection or replacement and thus improves productivity. For shops seeking predictable tool-change intervals, the hardened coating and robust substrate offer measurable gains in process stability.

Designed for quick mounting and secure clamping

The insert follows ISO form SNMG120404, ensuring compatibility with standard ISO turning holders when matched for form, clearance angle and tolerance class. The central cylindrical hole supports positive clamping and simplifies indexing; being double-sided, the insert provides two usable cutting edges, improving cost-efficiency per edge. The square 90° geometry with a 0.4 mm corner radius provides strength at the cutting tip and helps maintain dimensional accuracy on shoulder and profiling operations. Compatibility should be checked against holder specifications, notably seat form and screw type, to ensure correct fit and repeatable clamping force.

Practical benefits and selection guidance for process optimisation

Selecting the correct chipbreaker and grade is central to performance: the double-sided chipbreaker on this insert balances chip control and edge robustness, reducing the risk of built-up edge under variable feeds. The SNMG 120404 insert is well suited for general turning, finishing and medium-heavy roughing of steel when moderate toughness is required. For high-temperature or very abrasive conditions, consider alternative coatings or grades; for aluminium or non-ferrous materials a different chipbreaker geometry may be preferable.

FAQ

What materials is this insert intended for?
The SNMG 120404 T9225 turning insert is specified for medium to heavy machining of steel; the T9225 CVD-coated carbide provides toughness and wear resistance suited to variable engagement.

How is the insert clamped in the holder?
Clamping uses the central cylindrical hole together with the appropriate ISO holder and screw; the insert’s ISO geometry ensures repeatable seating when matched to a compatible holder.

How many cutting edges are available per insert?
This is a double-sided insert offering two usable cutting edges per side, effectively increasing the number of edges available before disposal.

Is the SNMG 120404 suitable for interrupted cuts?
Yes, the T9225 grade is designed for robustness and can handle slightly interrupted cuts where toughness is required.

Which parameters should be adjusted first to extend tool life?
Reducing depth of cut or feed during unstable engagement and ensuring correct speeds for the material will extend life; Metav Werkzeuge can provide application-specific parameters.
