CNMG120412 T9215 Tungaloy — ISO turning insert for medium-steel machining

The CNMG120412 T9215 Tungaloy is an ISO rhombic indexable insert designed for external and internal turning, combining a CVD-coated carbide grade with a double-sided chipbreaker for continuous to lightly interrupted cuts.

• ISO CNMG120412 rhombic insert, 80° geometry
• CVD-coated carbide grade T9215 for medium steel
• Double-sided chipbreaker with cylindrical hole
• 1.2 mm corner radius, 4.76 mm thickness

Consistent productivity through material-adapted coating and grade

The CVD-coated carbide grade T9215 was developed as a first choice for mid-range steel machining and pairs high wear resistance with good fracture toughness. In practice, this means longer useful life under continuous cuts and predictable tool-change intervals, which supports production planning. The coated substrate improves resistance to built-up edge and thermal wear, so cycle times remain reliable even under elevated cutting speeds. This technical composition contributes directly to process stability and cost-efficiency on medium-steel batches.

Practical compatibility and holder considerations for reliable setup

ISO conformity ensures straightforward matching with standard holders; compatibility is determined by insert form, clearance angle 0°, tolerance class, fastening type, size and thickness. The rhombic shape with 80° cutting angle and a cylindrical centre hole permits secure clamping and repeatable positioning in most external and internal turning fixtures. When selecting a clamping system, ensure the holder accepts CNMG 120412 geometry and accommodates the 4.76 mm plate thickness to maintain rigidity and avoid vibration-related wear.

Controlled chip formation and surface finish for higher throughput

A double-sided chipbreaker engineered for this insert geometry facilitates predictable chip evacuation across a range of feeds, reducing entanglement and time lost to manual chip clearing. The 1.2 mm corner radius balances edge strength and surface quality, allowing modest feed rates without compromising roughness. For shops aiming to increase throughput while keeping rework minimal, this combination supports higher machining windows and consistent part tolerances in medium-steel applications.

FAQ

What materials is this insert best suited for? The CNMG120412 T9215 insert is optimised for medium-steel machining; the T9215 CVD-coated carbide grade provides wear resistance and toughness suited to this material group.

How does the chipbreaker support machining stability? The double-sided chipbreaker on this indexable insert promotes consistent chip control and evacuation, reducing the likelihood of chip-related interruptions during turning operations.

Is the insert reversible or single-use per edge? This CNMG rhombic insert is double-sided, allowing indexation to present a fresh cutting edge when required, increasing effective tool life.

Which holders are compatible with CNMG120412 geometry? Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; confirm that the external holder accepts CNMG 120412 geometry and 4.76 mm thickness.

What is the significance of the 1.2 mm corner radius? A 1.2 mm corner radius provides a compromise between edge strength and surface finish, suitable for higher feed rates while maintaining consistent part quality.
