CNMG 120412 T9225 indexable insert for turning by Tungaloy

A robust CNMG120412 T9225 ISO indexable turning insert designed for medium to heavy steel machining, offering CVD-coated carbide and an 80° rhombic geometry for stable cuts.

• CNMG 80° rhombic insert, 4.76 mm thick
• CVD-coated carbide, grade T9225
• Double-sided chipbreaker, cylindrical hole
• Corner radius 1.2 mm for robust edge

Maximised productivity for medium-to-heavy turning

The combination of a CVD-coated carbide substrate and the T9225 grade delivers a balance of toughness and wear resistance that suits interrupted cuts and variable cutting conditions. This results in fewer insert changes and longer tool cycles, which increases machine uptime and reduces fixture change frequency. The rhombic 80° geometry concentrates cutting forces favourably for external and internal turning, which supports consistent dimensional control even under heavier feeds.

Reliable edge life and predictable surface finish

A 1.2 mm corner radius contributes to a robust cutting edge that tolerates increased depth of cut without premature chipping. The double-sided chipbreaker design promotes controlled chip formation and evacuation, reducing the risk of built-up edge on the rake face and improving surface integrity. For shops moving from general-purpose grades to a more resilient solution, this carbide combination reduces unscheduled stops and helps maintain repeatable surface quality in serial production.

Versatile compatibility with ISO toolholders and workpieces

Designed as an ISO CNMG120412 insert, the geometry and dimensions—including a 4.76 mm thickness and a cylindrical locating hole—ensure compatibility with standard CNMG toolholders when form, clearance angle, tolerance class, fastening and size match. The insert’s universal character makes it suitable across a wide range of steels; select the chipbreaker and grade to match feed, depth and stability for optimal results. The technical fit simplifies inventory management by aligning with common holder systems.

Practical handling and integration into machining processes

The rhombic shape and central hole support secure clamping and quick indexability on the seat, enabling fast presentation of fresh cutting edges. The CVD coating reduces flank wear at elevated temperatures, permitting higher cutting speeds compared with uncoated grades under comparable conditions. For operations requiring predictable cycle times, the insert’s construction supports consistent tool life and easier process parameter calculation, helping planners define cutting data with greater confidence.

FAQ

What materials is this insert suitable for?
The CNMG120412 T9225 Tungaloy indexable insert (SKU 6780917-Tungaloy) is formulated primarily for steel machining in medium to heavy applications; the T9225 grade offers toughness for varied engagement conditions.

How does the CVD coating benefit cutting performance?
The CVD-coated carbide on the CNMG120412 reduces flank and crater wear at elevated temperatures, enabling higher cutting speeds and improved tool life compared with uncoated substrates.

Is the insert compatible with standard CNMG toolholders?
Compatibility depends on matching form, clearance angle, tolerance class, fastening method, size and thickness; the CNMG120412 geometry aligns with common CNMG holders when those parameters are correct.

What advantage does the 1.2 mm corner radius provide?
A 1.2 mm corner radius enhances edge robustness, allowing increased depth of cut with lower risk of chipping and offering improved stability for heavy-duty turning operations.

How does the double-sided chipbreaker help in machining?
The double-sided chipbreaker promotes consistent chip formation and evacuation, reducing built-up edge and aiding surface finish while supporting indexability to present a fresh cutting edge when required.
