CNMG090412 T5115 — CNMG indexable turning insert for Turning by Tungaloy

The CNMG090412 T5115 is an ISO‑standard indexable turning insert designed for external and internal turning, optimised as a universal grade for cast iron machining.

• CVD-coated cemented carbide grade T5115
• ISO CNMG090412 rhombic geometry 80°
• Double-sided insert with cylindrical hole
• Balanced wear resistance and edge stability

Consistent cutting performance and extended tool life

The insert's CVD‑coated surface and cemented carbide substrate provide a controlled wear pattern that prolongs effective cutting life while maintaining dimensional stability. The T5115 grade is formulated as a universal solution for cast iron, combining abrasion resistance with edge robustness; this reduces changeovers and keeps production running. For shops seeking predictable repeatability, the combination of coating and grade translates into fewer interruptions and more consistent component quality.

Geometry that supports productive machining

The rhombic 80° geometry and a corner radius of 1.2 mm promote a sturdy cutting edge and stable engagement with the workpiece. A 0° rake angle and a 4.76 mm plate thickness contribute to rigidity in interrupted cuts and heavier depth passes, while the double‑sided design allows two usable cutting edges per face, improving economy. These features result in reliable surface finish and reduced tendency for chipping under typical turning conditions.

System compatibility and mounting considerations

Compatibility with toolholders depends on insert form, relief angle, tolerance class, clamping method, size and thickness. The ISO CNMG090412 form requires a matching CNMG‑type external holder or boring bar, appropriate clamping pad and the correct fixing screw or clamp. The insert is supplied with a cylindrical hole, facilitating secure location and repeatable seating in standard clamping systems. When integrating into an existing toolset, confirm holder radius and seating angle to preserve tolerance and tool life.

Practical selection and application advice

Select the T5115 grade and the double‑sided chipbreaker to match the cast iron alloy, cutting parameters and machine stability; a more rigid set‑up allows higher feed rates and longer tool life. For finishing or unstable setups, consider a smaller corner radius or adjusted cutting data to protect the edge. For tailored recommendations and cutting data sheets, technical consultation is available to match insert grade, chipbreaker style and holder choice to the specific workpiece and cycle time objectives.

FAQ

What materials is this insert best suited for?
The CNMG090412 T5115 insert is a universal grade developed for machining cast iron, offering a balanced combination of wear resistance and edge stability suitable for a wide range of grey and nodular cast irons.

How many cutting edges are available per insert?
The insert is double‑sided and provides multiple indexable edges; the rhombic CNMG form allows efficient rotation or indexing to present fresh edges, improving overall economy per insert.

Which holder types are compatible with this geometry?
Compatibility requires a CNMG‑compatible external holder or boring bar that matches the CNMG090412 form, 80° seating and the insert thickness of 4.76 mm; ensure the clamping method and pad geometry correspond to the insert's cylindrical hole.

What are the key geometric details to check before ordering?
Confirm the ISO designation CNMG090412, corner radius 1.2 mm, plate thickness 4.76 mm and the 80° geometry when selecting a holder and setting cutting parameters for stable, repeatable machining.

Can the insert handle interrupted cuts or heavier depths of cut?
Thanks to its robust cemented carbide substrate, 4.76 mm thickness and 80° geometry, the CNMG090412 T5115 insert tolerates interrupted cuts and heavier passes better than thinner or weaker geometries, particularly when used in a rigid setup.
