CNMA 120416 T5105 indexable insert for turning — CVD-coated carbide, 80° rhombic, 1.6 mm radius by Tungaloy

The CNMA120416 T5105 is an ISO-format indexable insert engineered for external and internal turning applications where repeatable geometry and high-speed capability are required.

• CVD-coated carbide grade T5105 for wear resistance
• 80° rhombic geometry for stable cutting forces
• 1.6 mm corner radius for robust tool life
• ISO-standard format for broad holder compatibility

Reliable high-speed turning with consistent results

This ISO-format insert combines a CVD coating with a carbide substrate to deliver elevated resistance to abrasive wear during demanding turning operations. The heat-resistant coating supports high-speed machining, reducing flank wear and keeping insert life predictable under stable cutting conditions. Because the grade is optimised for cast-iron applications, the insert maintains a consistent cutting edge, which translates into fewer interruptions and improved process efficiency. The result is measurable productivity gains and lower cost per component where stable set-ups are possible.

Geometry and mounting that simplify setup

The 80° rhombic geometry and a 1.6 mm corner radius provide a balance between edge strength and accessibility into profiles. The insert’s ISO dimensions and cylindrical central hole enable secure clamping in standard indexable holders; compatibility depends on form, clearance angle, tolerance class, clamping method, size and thickness. Clear, repeatable indexing reduces setup time and helps maintain surface finish targets. For workshops aiming to standardise inserts across machines, the ISO designation supports easier procurement and inventory control.

Grade performance and material fit

Grade T5105 is a CVD-coated carbide designed for productive machining of cast iron under steady conditions. The combination of substrate and coating improves resistance to thermal and abrasive stresses, keeping the cutting edge intact during continuous cuts. This makes the insert particularly suitable for medium to heavy roughing and finishing passes in cast-iron components, where reliable chip evacuation and an even wear pattern are key to achieving consistent part quality and dimensional repeatability.

Practical benefits for shop-floor decision-making

Selecting an ISO insert with a defined clearance angle and standard thickness simplifies holder matching and reduces the risk of incorrect assembly. The rhombic form and included hole design allow flexible use in both external and internal turning operations when the correct holder and clamping set are chosen. Maintenance intervals can be lengthened thanks to predictable wear behaviour, and consistent insert geometry aids downstream processes by lowering rework rates. For teams assessing tooling options, the insert represents a technically clear choice when machining cast-iron under controlled, stable setups.

FAQ

What materials is this insert best suited for?
The CNMA120416 T5105 insert is optimised for machining cast iron; the T5105 CVD-coated carbide grade offers high wear resistance for such applications.

How does the 80° rhombic geometry affect cutting performance?
The 80° rhombic shape provides stable cutting forces and good access to external and internal profiles, improving edge strength and adaptability in varied turning tasks.

Is this insert compatible with standard ISO holders?
Yes, the insert follows ISO dimensions; compatibility with a holder depends on form, clearance angle, tolerance class, clamping style, size and thickness — verify these parameters when selecting the holder.

What does the absence of a chipbreaker mean for operations?
With no chipbreaker specified, the insert is intended for operations where chip formation is managed by process parameters, tooling arrangement or is less critical; selection should consider material, feed and stability.
