CNMA 160616 T515 Wendeplatten - Tungaloy

Take advantage of the combination of a proven CVD-coated carbide T515 grade and the ISO CNMA form for efficient, reliable cast iron turning; compatibility with standard CNMA holders reduces changeover time and improves process stability. Order the original inserts via Metav Werkzeuge or ask the consultants for holder compatibility.

CNMA 160616 T515 Turning insert — Tungaloy

CNMA160616 T515 is an ISO rhombic turning insert designed for economic machining of cast iron in ISO CNMA systems

• CNMA 160616 ISO designation
• CVD-coated T515 carbide grade
• Designed for cast iron turning
• Rhombic form with 80° included angle

Consistent performance in cast iron turning

The CNMA160616 design combines a CVD-coated carbide substrate with the T515 grade to provide wear resistance and stable edge behaviour during continuous cutting of cast iron. The CVD coating (chemical vapour deposition) forms a hard outer layer that improves abrasion resistance and extends effective tool life, which translates into fewer insert changes and higher productive uptime. For practical use this means consistent surface finish and predictable tool-change intervals in serial turning operations.

Secure clamping and ISO compatibility for reliable production

Compatibility is determined by form, clearance angle 0°, tolerance class, fastening, size and thickness; the rhombic geometry with an 80° included angle and a cylindrical central hole ensures secure seating in standard CNMA-compatible toolholders. Secure clamping reduces chatter and vibration, improving both tool life and dimensional consistency. The indexable insert format simplifies tool replenishment and reduces setup-related downtime in a production environment.

Practical dimensions and machining benefits for workshop efficiency

With a nominal size of 16 mm, a thickness of 6.35 mm and a corner radius of 1.6 mm, this insert balances edge strength and cutting performance: the 1.6 mm radius increases corner robustness for medium-heavy cuts while still allowing acceptable surface quality. The absence of an integral chipbreaker means this insert is best applied where chip evacuation is uncritical or where external chip control measures are in place; selecting an appropriate holder and cutting parameters optimises chip flow.

FAQ

What materials is this insert suited for?
The CNMA160616 T515 insert is engineered primarily for machining cast iron; the T515 CVD-coated carbide grade offers abrasion resistance suitable for a broad range of grey and ductile cast irons.

How does the 1.6 mm corner radius affect cutting?
A 1.6 mm corner radius provides enhanced corner strength for medium to heavy cutting, reducing the risk of edge chipping and supporting stable tool life under higher feed rates.

Is a chipbreaker required with this insert?
This insert is supplied without a chipbreaker; pairing the insert with a compatible holder and optimised cutting parameters is recommended to control chip formation and evacuation.

Which holders are compatible with this insert?
Compatibility depends on holder form, tolerance class, fastening method, size and thickness; use holders specified for CNMA inserts with an 80° included angle and matching seat geometry for secure clamping.

What benefits does the CVD coating provide?
The CVD coating improves surface hardness and wear resistance, leading to longer edge life and consistent cutting performance, especially in abrasive cast iron applications.
