SNMG120404 T9225 SNMG Turning insert for Turning by Tungaloy – CVD-coated carbide, 0.4 mm corner radius

The SNMG120404 T9225 is an ISO‑standard SNMG indexable insert designed for dependable medium-to-heavy turning of steel, optimised for varying engagement conditions and lightly interrupted cuts

• CVD-coated carbide Grade T9225
• ISO SNMG120404 form, 12 mm square
• 0.4 mm corner radius for strength
• Dual-sided chipbreaker with cylindrical hole

Consistent cutting performance for steel applications

The CVD‑coated T9225 grade delivers a balance of toughness and wear resistance that suits medium-to-heavy steel machining. The coating reduces flank wear and extends effective tool life under fluctuating loads, while the 0.4 mm corner radius increases edge strength for semi‑roughing passes. As a result, the insert ensures repeatable dimensional accuracy and a predictable tool-change interval, supporting sustained production runs with less unplanned downtime.

Easy integration into ISO tooling systems and secure clamping

Built to ISO dimensions, the SNMG120404 form guarantees compatibility with standard square insert holders and boring bars; fitment depends on form, relief angle and thickness. The insert is supplied with a cylindrical hole and a double-sided chipbreaker, enabling secure fastening and reversible use to halve tooling costs per edge. The 0° relief angle and a 90° included angle provide stable seating in the holder, so clamping forces remain uniform and vibration is minimised—benefits that directly improve surface finish and tool life.

Productivity and process stability benefits

The carbide substrate and CVD-coated surface of the grade deliver controlled wear progression, which reduces the frequency of tool changes and the risk of sudden edge failure during interrupted cuts. The dual-sided chipbreaker offers reliable chip control across a range of depths of cut, lowering cycle times and improving operator confidence at higher cutting speeds. For production environments, these attributes translate into better machining economy and consistent part quality across batches.

FAQ

What materials is this insert best suited for?
The SNMG120404 T9225 insert is optimised for medium-to-heavy steel machining, offering toughness for variable engagement and lightly interrupted cuts.

Is the insert reversible and how does that affect costs?
Yes, the insert is double‑sided; reversing the insert halves the cost per cutting edge and extends the service life before disposal.

What does the T9225 grade mean for production runs?
Tungaloy’s T9225 is a robust universal grade with a CVD coating that promotes stable wear behaviour and consistent performance during longer cycle times.

Can this insert be used in holders from different manufacturers?
The SNMG120404 form follows ISO geometry; compatibility depends on holder design, clamping method and tolerance class—ensure the holder matches the ISO SNMG specifications.

How does the cylindrical hole help in clamping?
The cylindrical hole is intended for positive location and secure screw clamping, improving seating stability and reducing the risk of insert movement under load.
