CNMG 120412 T9235 — ISO turning insert by Tungaloy, for external and internal turning

A CNMG 120412 T9235 ISO turning insert designed for steel machining where interrupted cuts and less rigid setups demand a tough, wear-resistant grade and secure chip control

• CVD-coated carbide for robust cutting
• Designed for steel under interrupted cuts
• Double-sided chipbreaker for versatile use
• ISO rhombic plate with 80° cutting angle

Longer tool life through a wear-resistant grade

The combination of a CVD coating with a tough carbide substrate gives this grade a clear advantage when machining steels at reduced cutting speeds or under unstable conditions. The T9235 formulation emphasises stable chip formation and resistance to abrasive wear, which translates into fewer insert changes and a more constant process output. For operations where surface finish consistency and predictable regrinds matter, a wear-resistant insert reduces downtime and contributes to overall cost-efficiency in series production.

Reliable fitment and predictable assembly for quick tool changes

Compatibility within an ISO system depends on geometric parameters and tolerance classes rather than brand-specific designs. The plate’s rhombic form and 80° cutting angle, together with a 0° clearance angle, a plate thickness of 4.76 mm and a corner radius of 1.2 mm, ensure a defined seating in matching holders. The insert’s central cylindrical hole accommodates standard clamping screws and shims; therefore, selection of an appropriate external holder or boring bar requires matching the plate form, size and thickness to the clamping set. This standardised approach simplifies inventory and speeds replacement during production.

Consistent chip control and performance in interrupted cuts

A double-sided chipbreaker provides two usable cutting edges and a controlled fragmentation pattern that improves evacuation in turning operations. In practice, choosing the correct chipbreaker and grade to suit the workpiece steel and machining stability is decisive: a robust chip control design helps avoid built-up edge and improves repeatability when cuts are irregular or interrupted. For workshops facing a mix of stable and unstable setups, this insert offers a balance between process security and flexibility, helping to maintain surface quality without excessive adjustments.

System-focused handling that supports productivity

The insert is part of an ISO system comprising the indexable plate, a suitable holder, a shim or clamping set and replacement screws. Using matching components reduces set-up time and ensures repeatable clamping forces, which supports tool life and machining accuracy. Planning tool changes around standardised inserts like this enables fast stock rotation and lowers logistical complexity. For clear traceability, the item is supplied with manufacturer and SKU references, which simplifies reordering and tool management in production environments.

FAQ

What materials is this insert optimised for?
The CNMG 120412 T9235 insert is optimised for machining steel in conditions with interrupted cuts or reduced cutting speeds; the T9235 carbide grade is balanced for toughness and wear resistance.

Will this insert fit existing ISO holders?
Compatibility is determined by plate form, free/clearance angle, tolerance class, fastening method, size and thickness; the rhombic shape, 80° angle and 4.76 mm thickness match ISO holder specifications for this plate type.

How does the double-sided chipbreaker benefit production?
The double-sided chipbreaker provides two cutting edges per insert and consistent chip fragmentation, improving evacuation and repeatability in turning operations with variable cut conditions.

Is the coating suitable for mixed production batches?
The CVD coating on this carbide grade offers broad applicability across different steel grades and is particularly helpful when batch work includes interruptions or unstable setups.

What references identify this product for reorders?
Use the manufacturer article number 6785906 or the manufacturer SKU TUN6785906 when reordering to ensure the exact CNMG120412 T9235 specification is supplied.
