CNMA 160612 T5125 — Turning indexable insert, rhombic 80°, Tungaloy

The CNMA160612 T5125 is an ISO-format indexable insert for turning, engineered for external and internal machining and optimised for cast iron under interrupted cutting conditions.

• ISO turning insert CNMA 160612 T5125
• CVD-coated carbide grade T5125
• Rhombic shape with 80° included angle
• 1.2 mm corner radius, 6.35 mm thickness

Stable cutting under interrupted conditions for predictable productivity

The CVD-coated carbide formulation and the tougher T5125 grade deliver increased resistance to chipping during interrupted cuts, which translates into fewer unplanned tool changes and more consistent cycle times. The combination of a rhombic plate form and an 80° included angle provides a balance between edge strength and versatility for turning tasks. By selecting a grade designed for less stable conditions, operators gain improved process stability and a clearer path to maintaining production throughput on mixed or challenging workpieces.

Simple integration in ISO tool systems for fast tool changes

As an ISO-standard indexable insert, compatibility is determined by plate form, clearance angle, tolerance class, fastening method, size and thickness. The CNMA format with a cylindrical hole and specified dimensions (16 mm across, 6.35 mm thickness) fits common external holders and boring bars when matched correctly. Knowing the insert’s key parameters — including the 0° clearance angle and 1.2 mm corner radius — helps machining planners choose an appropriate holder and clamping set, reducing setup time and minimising ambiguity at the machine.

Material focus and surface quality advantages for cast iron components

The T5125 composition is tailored for machining cast iron, providing predictable chip control and a compromise between toughness and wear resistance. In practice, this means more consistent surface finish and repeatable part geometry when turning both external and internal features. Selecting the correct chipbreaker and inserting a grade matched to the part material reduces the risk of edge failure and supports extended tool life, improving overall cost-efficiency per component and lowering scrap rates in production.

Practical guidance for selection and application

Choose the insert grade and chipbreaker to match the specific casting type, depth of cut and machine stiffness; smoother cast irons with lighter interruptions permit more aggressive parameters, while heavily interrupted or less rigid setups benefit from the tougher T5125 grade. Corner radius and included angle affect both strength and finish—1.2 mm corner radius offers a robust contact edge while maintaining acceptable surface quality. For any uncertainty regarding holder compatibility or process parameters, consulting technical documentation or a tooling specialist ensures the correct combination of holder, shim and screw for the application.

FAQ

What materials is this insert best suited for?
The CNMA160612 T5125 turning insert is optimised for cast iron applications and performs well under interrupted cutting conditions thanks to the tougher T5125 grade.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the CNMA 160612 format fits standard ISO-compatible external holders and boring bars designed for CNMA plates.

What does the T5125 designation indicate?
T5125 denotes a CVD-coated carbide grade formulated for increased toughness, making the insert suitable for less stable conditions and intermittent machining of cast iron.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm corner radius increases edge strength and reduces the likelihood of chipping, improving durability in interrupted cuts while still providing acceptable surface finish.

Is this insert suitable for internal turning?
Yes, the ISO CNMA geometry and the 6.35 mm thickness allow use in appropriate boring bars for internal turning, provided the holder supports CNMA inserts.

How to identify the insert for reordering?
Order using the designation CNMA160612 T5125 and the manufacturer article number 6850162 or SKU 6850162-Tungaloy to ensure the correct Tungaloy indexable insert is supplied.
