CNMG 120412 T9215 turning insert — Tungaloy

The CNMG 120412 T9215 insert is an ISO‑format, rhombic indexable cutting insert designed for turning applications in medium steel, offering a balance of wear resistance and fracture toughness for continuous to slightly interrupted cuts

• ISO turning insert CNMG format
• CVD-coated T9215 grade for medium steel
• 1.2 mm nose radius for general turning
• Rhombic 80° geometry with cylindrical hole

Faster cycles through wear‑resistant grade and proven coating

The combination of a CVD‑coated carbide substrate and the T9215 grade provides enhanced wear resistance while retaining sufficient toughness to avoid premature fracture. This results in longer tool life and fewer indexings per component, which in turn reduces total cycle times and tool change frequency. For production environments pursuing stable throughput, the insert’s formulation supports higher cutting parameters in continuous turning and in lightly interrupted cuts without sacrificing surface consistency.

Stable cutting behaviour from geometry and chip control

The rhombic 80° geometry and 0° relief promote secure engagement with the workpiece and predictable cutting forces; the double‑sided chipbreaker aids chip control across common feed ranges. The 1.2 mm nose radius gives a reliable compromise between edge strength and surface finish, helping to maintain dimensional accuracy on external and internal turning operations. Where repeatability and clamping security are required, the cylindrical hole ensures consistent seat alignment and correct tightening in compatible holders.

Seamless integration into ISO‑based turning systems

As an ISO turning insert, compatibility depends on matching form, relief angle, tolerance class, fastening method, size and thickness with the chosen toolholder. The CNMG 120412 format fits established external holders and boring bars that accept rhombic inserts with a central hole. Selection of the T9215 grade and the double‑sided chipbreaker should be aligned with workpiece material, rigidity of the machine–tool–workpiece system and the expected cutting mode to fully exploit the insert’s productive potential.

FAQ

Which materials is this insert optimised for?
The Tungaloy CNMG 120412 T9215 insert is optimised for medium steel machining; the T9215 grade combines wear resistance and toughness for productive turning.

Is the insert reversible or single‑edged?
The CNMG120412 design is double‑sided with a chipbreaker on both faces, allowing indexing to the alternate cutting edge to extend service life.

What are the key dimensions to check for holder compatibility?
Important dimensions are the ISO designation CNMG120412, thickness 4.76 mm, insert size 12 mm and the 1.2 mm nose radius; matching relief angle and hole style is essential for correct seating.

How does the chipbreaker affect cutting performance?
The double‑sided chipbreaker provides controlled chip formation across typical feeds for turning, improving surface finish and reducing the risk of long stringy chips in steady cutting conditions.
