CNMG 120416 T9215 Tungaloy turning insert — ISO CNMG, 80° rhombic, CVD-coated carbide

The CNMG120416 T9215 is an ISO-standard turning insert designed for external and internal turning of medium steels, offering a balanced combination of wear resistance, fracture safety and suitability for continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215 for medium steel
• ISO rhombic insert CNMG 80° geometry
• 1.6 mm corner radius for stable cutting
• Double-sided chipbreaker with cylindrical hole

Faster, more consistent metal removal for medium-steel turning

The CVD-coated carbide grade T9215 provides a high level of wear resistance while retaining sufficient toughness to avoid premature chipping under continuous or slightly interrupted cuts. The coating reduces flank and crater wear and extends effective edge life, which translates into improved operating efficiency and longer tool change intervals. For production environments where cycle time and repeatability matter, this specification supports higher metal removal rates and consistent component quality without sacrificing process reliability.

Secure seating and broad compatibility with ISO holder systems

As an ISO-design insert, compatibility with clamping systems is governed by shape, clearance angle, tolerance class, fastening, size and thickness. The rhombic 80° geometry confers mechanical strength and application versatility, while the cylindrical hole ensures positive locating and secure clamping in standard CNMG holders. Typical system components include the appropriate external holder or boring bar, a shim or clamping set and spare screws; selecting matched components reduces setup variance and improves overall process stability.

Predictable surface finish and controlled chip formation

The R1.6 corner radius and the double-sided chipbreaker are configured to support steady cutting forces and effective chip control, which together enhance final surface finish and reduce vibration. For medium-steel applications, this combination helps to maintain dimensional accuracy across long production runs and makes the insert suitable for both general turning and finish operations when machining conditions and rigidity are adequate. Selecting the correct chipbreaker and grade for the specific workpiece material and machine rigidity further optimises productivity.

FAQ

Which materials are best suited to this insert?
The CNMG120416 T9215 turning insert is optimised for medium steel machining; the T9215 grade balances wear resistance and toughness for productive turning of such materials.

How many usable cutting edges does the insert provide?
Being double-sided and rhombic, the insert offers multiple indexable edges; the CNMG120416 Tungaloy insert (SKU 6772183-Tungaloy) is designed for economical indexing and extended tool life.

What does the 80° geometry mean for operation?
The 80° approach angle increases edge strength and stability, making the insert suitable for general turning tasks where robustness and versatility are required.

Is the insert compatible with standard CNMG holders?
Yes — as an ISO CNMG insert, compatibility depends on matching shape, size, thickness and fastening; secure clamping is supported by the cylindrical locating hole.

When should a different chipbreaker or grade be chosen?
If the application involves heavy interruptions, exotic alloys or very high cutting speeds, a different chipbreaker or grade should be selected to match rigidity and thermal demands; the T9215 grade suits continuous to lightly interrupted medium-steel turning.
