SNMG120412 T9225 Turning Insert – CVD-coated carbide, 1.2 mm radius (Tungaloy)

SNMG120412 is a square, ISO‑format turning insert optimised for robust steel machining and compatible with standard SNMG holders

• CVD-coated carbide for steel machining
• Robust universal grade T9225
• ISO SNMG120412 form for wide holder compatibility
• Double-sided chipbreaker for stable chip control
• Cylindrical hole, square 12 mm plate

Engineered for reliable, repeatable metalcutting results

The insert’s CVD-coated surface and carbide substrate are selected to balance wear resistance and toughness for demanding turning tasks. The T9225 grade is formulated as a universal, robust option for medium to heavy steel machining, especially where changing engagement or light interruptions occur. In production environments this combination reduces frequency of tool change and helps maintain steady cycle times, supporting predictable process planning and lower overall tooling cost.

Stable cutting edge and improved process security

A 1.2 mm corner radius and 4.76 mm plate thickness provide a reinforced cutting edge that tolerates higher cut depths and variable feeds without premature chipping. The double-sided chipbreaker delivers consistent chip formation on both index positions, aiding chip evacuation and surface finish while extending usable lifetime of each index. These design choices translate into fewer unplanned stops and more consistent part quality on turned components.

Simple integration into ISO turning systems

As an ISO‑format SNMG insert, this item integrates into common external and internal turning tool systems. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; the square SNMG geometry and cylindrical hole suit many clamping concepts. A typical system consists of the insert, a matching external holder or boring bar, a shim/clamp set and the securing screw. Checking those parameters ensures correct seating, repeatable positioning and safe clamping during machining.

Practical benefits for workshop workflows

The design focusses on operational efficiency: robust edge geometry reduces rework, CVD-coated surfaces enhance abrasion resistance and the universal grade helps cover varying steel alloys with one insert type. Typical applications include external and internal turning where stability and chip control are required. For specification matching or process selection, consult technical guidance to choose the optimal chipbreaker and grade for the workpiece and machining conditions.

FAQ

Which holders fit this SNMG insert?
The SNMG120412 insert fits holders that accept SNMG‑form inserts; compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness. Check the holder specifications against the SNMG120412 dimensions and clamping style.

What materials is the grade suitable for?
The T9225 grade is a robust universal choice optimised for steel machining; SNMG120412 is recommended for medium to heavy steel turning where toughness and stable chip control are required.

What does the T9225 designation indicate?
T9225 denotes a CVD‑coated carbide grade tailored for productivity and reliable edge behaviour in tougher turning conditions; it balances wear resistance with fracture toughness for interrupted or variable cuts.

Is the insert indexable on both sides?
Yes, the double‑sided chipbreaker design allows the insert to be indexed to alternate faces, extending the effective tool life before replacement.

How should the insert be mounted for secure clamping?
Mount SNMG120412 in an SNMG‑compatible holder with the correct shim or clamp set and the matching securing screw; ensure clean seating and correct torque per the holder manufacturer’s instructions.
