CNMA 120404 T5115 turning insert for turning by Tungaloy

CNMA120404 T5115 is an ISO‑format indexable turning insert designed for efficient external and internal turning of cast iron, combining a CVD coating with a balanced carbide substrate for reliable edge stability.

• ISO‑standard CNMA geometry
• CVD‑coated carbide grade T5115
• Suitable for cast‑iron machining
• 0.4 mm corner radius, 80° cutting angle

Consistent tool life through a CVD‑coated carbide grade

The combination of a CVD‑coated surface and a robust carbide substrate in this insert offers a predictable wear curve and improved resistance to abrasion compared with uncoated grades. The T5115 specification provides a balance between edge stability and wear resistance, making it suitable for longer tool life in interrupted cuts and varying cast‑iron compositions. For shop floors where repeatability and reduced tool changes matter, the coating helps maintain cutting performance and reduces unexpected downtime.

ISO geometry for straightforward holder matching and setup

Built to the ISO CNMA form, the insert’s profile, relief angle and tolerance class ensure compatibility with a broad range of standard external holders and boring bars. Correct alignment relies on matching the insert’s form, relief angle (0°), thickness (4.76 mm) and fastening arrangement; when these match the holder specifications, clamping stability and repeatable positioning follow. This standardisation simplifies tooling logistics and minimises setup time, supporting a smoother production flow.

Practical advantages on workpieces and surface quality

With a 0.4 mm corner radius and a nominal 80° included angle, the geometry favours stable cutting forces and predictable component geometry, helping to produce a consistent surface finish on cast‑iron parts. The insert is supplied without a chipbreaker, allowing the selection of the most suitable chip control solution for the machine rigidity and cutting conditions. Where vibration control and chip evacuation are critical, choosing an appropriate holder or a matched chipbreaker will enhance the overall productivity and final component quality.

FAQ

Is this insert suitable for machining cast iron? This CNMA120404 T5115 turning insert is a universal grade formulated for cast‑iron machining, offering a balance of wear resistance and edge stability tailored to that material class.

How is holder compatibility determined for this insert? Compatibility depends on matching the insert’s form, relief angle, tolerance class, fastening method, size and thickness to the intended external holder or boring bar; ISO CNMA geometry simplifies this matching process.

Can the insert be used without a chipbreaker? Yes — the insert is supplied without a chipbreaker; this allows selection of a chip control solution appropriate to the workpiece, machine rigidity and cutting parameters for optimal chip formation.

What benefits does the CVD coating deliver? The CVD coating on the T5115 grade improves abrasion resistance and helps maintain a sharp cutting edge under varying cast‑iron conditions, supporting longer tool life and consistent component quality.
