TNMG 220412 T5125 indexable turning insert for turning – Tungaloy

TNMG 220412 T5125 indexable insert for ISO‑compliant external and internal turning, designed for interrupted cuts and less stable machining conditions

• Double-sided chipbreaker for stable chip control
• CVD-coated carbide grade T5125 for cast iron
• Triangle 22 mm form with 60° cutting angle
• 1.2 mm corner radius, 0° clearance angle

Delivering consistent process reliability and extended tool life

The CVD‑coated T5125 grade combines a wear‑resistant surface with a tougher substrate, producing longer tool life under fluctuating cutting conditions. For production environments where interruptions and varying stability are common, this combination reduces unplanned tool changes and supports higher machine utilisation. The coating improves resistance to built‑up edge and abrasive wear, while the carbide core maintains edge strength for heavy engagement, resulting in measurable gains in productivity.

Easy integration into ISO tool systems for predictable performance

Manufactured to the ISO geometry TNMG 220412, the insert fits holders that match form, clearance, tolerance class, attachment and thickness. The insert’s cylindrical hole and standardised dimensions simplify replacement and inventory management. Using ISO‑rated components ensures repeatable clamping and alignment, which translates into process reliability and consistent part quality across shifts and machines without complex adjustments.

Improved surface finish and reduced vibration through optimised geometry

The triangular 22 mm form with a 60° cutting angle and a 1.2 mm corner radius balances edge strength and surface integrity. The double‑sided chipbreaker actively manages chips to prevent entanglement and minimise vibration, which is especially beneficial in less rigid setups. Proper chip control leads to better surface finish on cast iron workpieces and reduces the risk of tool edge chipping during interrupted cuts, supporting steadier cycle times and fewer reworks.

Practical application guidance and system setup for reliable results

Intended for turning operations, the insert performs best when paired with a suitable external holder or boring bar, a matching locating pad and clamp set, plus correct tightening screws. Selection of the right chipbreaker and grade should be guided by workpiece material, cutting strategy and machine rigidity. For interrupted cuts in cast iron, the tougher T5125 grade is recommended to absorb shock and maintain cutting edge integrity while preserving machinability and throughput.

For dependable machining of cast iron and interrupted turning tasks, rely on genuine Tungaloy TNMG 220412 T5125 inserts and request application advice or procurement through Metav Werkzeuge, where experienced consultants can provide specification support and availability information.

FAQ

What materials are suitable for this insert?
The TNMG 220412 T5125 insert is formulated for cast iron machining; the T5125 CVD coating and tougher carbide substrate make it particularly effective for interrupted cuts in cast iron.

How does the double‑sided chipbreaker help in production?
A double‑sided chipbreaker on this indexable insert improves chip formation and evacuation, reducing vibration and promoting a more consistent surface finish during turning operations.

Which holders will accept the TNMG 220412 insert?
ISO‑compliant TNMG holders and compatible boring bars with the matching form, attachment and tolerance class accept this insert; the cylindrical hole ensures standard clamping and repeatable seating.

What cutting edge features influence performance?
The 1.2 mm corner radius and 60° geometry provide a balance of edge strength and finish quality, while the 0° clearance angle suits many external and internal turning setups.

Is this insert reversible or single‑use?
The triangular form with chipbreaker on both sides allows indexing of multiple edges, extending usable edges per insert and improving cost efficiency.
