CNMG190616 T5125 Tungaloy indexable insert — ISO rhombic turning insert for cast iron

The CNMG190616 T5125 is an ISO rhombic indexable turning insert engineered for external and internal turning of cast iron, optimised for interrupted cuts and less stable machining conditions.

• CVD-coated carbide grade T5125
• Rhombic 80° shape with 1.6 mm radius
• Double-sided chipbreaker for consistent chips
• Cylindrical hole and 6.35 mm thickness

Increased process reliability and predictable tool life

The CVD-coated carbide composition and T5125 grade deliver a balance of toughness and wear resistance that reduces the risk of premature edge failure in interrupted cuts. This combination supports a stable cutting edge under varying conditions and contributes to longer tool life, meaning fewer indexings and less machine downtime. The ISO designation ensures compatibility within standard turning tool systems, simplifying inventory management and repeatability in production runs.

Optimised for cast iron turning and roughing operations

Designed specifically with cast iron operations in mind, the insert’s geometry and double-sided chipbreaker promote secure chip control and help avoid troublesome built-up edge formation. The 1.6 mm corner radius provides strength at the cutting edge for roughing passes, while the rhombic 80° shape gives access for a wide range of turning profiles. These features translate into effective material removal rates and improved surface finishes when the cutting data is matched to the workpiece and machine rigidity.

Simple selection and secure mounting for workshop integration

Compatibility with a holder is defined by the insert’s form, relief angle, tolerance class, fastening method, size and thickness; the CNMG190616 therefore fits ISO holders that match these parameters. The cylindrical hole facilitates secure clamping and repeatable seating, while the 6.35 mm thickness adds stiffness in demanding cuts. Where uncertainty exists, reference the ISO series and holder specification to confirm the correct assembly and to avoid mismatches that could affect performance.

FAQ

What materials is this insert intended for?
The insert is optimised for cast iron machining and the CNMG190616 T5125 grade is formulated for interrupted cuts and less stable conditions.

How is compatibility with tool holders determined?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; matching those ISO parameters ensures correct fitment for the insert.

Does the insert support secure clamping?
The insert features a cylindrical hole which enables reliable clamping and repeatable seating in compatible holders.

What advantages does the CVD coating offer for this grade?
The CVD coating on this carbide grade enhances wear resistance while retaining sufficient toughness for interrupted cutting, improving edge life under variable loads.

What is the corner radius and how does it affect cutting?
The corner radius is 1.6 mm; this radius reinforces the cutting edge for roughing passes and improves resistance to chipping during heavy engagement.
