SNMG 120412 T5105 — turning insert for turning, Tungaloy

The SNMG120412 T5105 is an ISO-standard indexable turning insert optimised for high‑speed machining of cast iron under stable cutting conditions.

• CVD-coated carbide grade T5105
• Optimised for high-speed cast iron turning
• SNMG 90° square insert with 1.2 mm radius
• Double-sided chipbreaker, cylindrical hole for fixing

Engineered for reliable high‑speed machining

Designed around a CVD-coated carbide T5105 grade, this indexable insert provides elevated wear resistance and thermal stability that support increased cutting speeds in repetitive turning tasks. The coating improves abrasive and adhesive wear behaviour, which translates into longer in‑process tool life and more consistent component dimensions. For machining operations on cast iron, the combination of substrate and coating promotes controlled chip formation and reduced flank wear, aiding predictable cycle times and fewer in‑process interruptions.

Precise geometry and ISO compatibility for predictable fits

The ISO designation guarantees that the insert fits within established holder systems when form, relief angle, tolerance class, clamping and size match. The square, 90° arrangement and 1.2 mm corner radius balance edge strength and accessibility for profile work, while the 0° relief establishes a neutral clearance useful in many external and internal turning setups. The insert is double-sided and features a cylindrical hole, enabling secure clamping and economical indexing; compatibility should be checked against the specific holder geometry and tolerance class to ensure the expected repeatability and clamping force.

Operational benefits: productivity, handling and stability

As a two‑face indexable solution with an integrated chipbreaker, the insert reduces tool change frequency and supports consistent chip control under the intended stable cutting conditions. The chipbreaker design assists in producing manageable swarf, which contributes to safer machine operation and fewer interruptions for clearing. Using an ISO‑compliant insert simplifies inventory management and eases replacement compared with bespoke geometries. Where machining stability is present, this configuration helps maintain surface finish and dimensional control while keeping spindle time efficient.

FAQ

Is the SNMG120412 compatible with standard ISO turning holders?
The SNMG120412 is an ISO‑design insert; compatibility depends on holder form, relief angle, tolerance class, clamping and size — confirm the holder accepts SNMG geometry before fitment.

Which materials is this grade suited for?
Grade T5105 with a CVD coating is specified for wear‑resistant, high‑speed machining of cast iron; the SNMG120412 insert performs best under stable cutting conditions on cast iron.

What are the fixing and clamping characteristics?
The insert features a cylindrical hole for positive clamping and a square, 90° shape that, when assembled with the correct clamping set, provides secure indexing and repeatable positioning.

How does the chipbreaker affect machining?
The double‑sided chipbreaker supports controlled chip formation and evacuation, which promotes consistent surface finish and reduces the need for manual swarf handling during turning operations.

Which SKU should be ordered for this specific insert?
Order using SKU 6850263‑Tungaloy or Manufacturer SKU TUN6850263 to ensure the SNMG120412 T5105 insert from Tungaloy is supplied.
