CNMG 120412 T5105 turning insert — CVD‑coated carbide by Tungaloy

The CNMG120412 T5105 is an ISO‑standard indexable turning insert for stable, high‑speed machining of cast iron, intended for both external and internal turning operations.

• CVD‑coated carbide T5105
• Designed for high‑speed cast iron turning
• ISO CNMG 120412 rhombic format
• Dual‑sided chipbreaker, cylindrical hole

Consistent wear performance for high‑speed turning

The CVD‑coated carbide grade T5105 delivers reliable wear resistance under high‑speed conditions, extending insert life and reducing downtime. The chemical vapour deposition coating forms a hard, heat‑resistant layer that retards flank and crater wear during extended cycles, which means fewer indexings and steadier surface finishes. For production environments focused on throughput, the combination of a robust carbide substrate and CVD protection translates into measurable gains in process stability and lower tool‑related interruptions.

Predictable fit and rigidity for repeatable results

Designed to the ISO CNMG form, the rhombic insert with its 80° principal angle and 0° clearance ensures predictable seating in standard holders; compatibility is determined by form, free angle, tolerance class, fastening, size and thickness. The insert thickness of 4.76 mm and 12 mm size fit common external holders and boring bars, while the cylindrical hole facilitates secure clamping and correct orientation. These dimensional standards allow easy tool‑change routines and support reproducible part quality across batches.

Practical selection and recommended use in production

Select the dual‑sided chipbreaker variant and the T5105 grade when working on cast iron under stable, well‑supported conditions to exploit the insert’s high‑speed capability. The moderate corner radius of 1.2 mm is a good compromise between edge strength and surface finish; larger radii increase edge durability, smaller radii improve detail and form accuracy. For system setup, pair the insert with a compatible ISO holder, a correct underlay or clamp kit and replacement screws to ensure consistent clamping force and repeatable results. When in doubt, consult production data sheets or our technical advisors for cutting speed and feed recommendations tailored to the workpiece and machine rigidity.

FAQ

What materials is this insert best suited for? The CNMG120412 T5105 insert is formulated for high‑speed machining of cast iron; the CVD‑coated carbide grade provides wear resistance suited to stable turning conditions.

Will this insert fit standard CNMG holders? Yes, the CNMG120412 follows ISO dimensions, so compatibility with standard CNMG holders is determined by form, free angle, tolerance class, fastening, size and thickness.

What does the T5105 designation indicate? T5105 denotes a CVD‑coated carbide grade engineered for wear resistance during high‑speed turning, offering a balance of edge stability and coating adhesion.

How does the dual‑sided chipbreaker affect performance? The dual‑sided chipbreaker supports reliable chip control in both orientations, improving surface quality and enabling economical use of multiple indexed cutting edges.

Which corner radius and thickness considerations apply for finishing vs roughing? A 1.2 mm corner radius and 4.76 mm thickness deliver a compromise between edge life and surface finish; for heavy roughing select larger radii and ensure adequate machine rigidity.
