CNMM190612 T9225 CNMM Turning Insert by Tungaloy – ISO rhombic 80°

A CNMM190612 Tungaloy ISO rhombic turning insert engineered for medium-to-heavy steel turning with a CVD-coated carbide substrate and a single-sided chipbreaker.

• ISO CNMM190612 geometry, 80° rhombic
• CVD-coated carbide, T9225 grade
• Nose radius 1.2 mm for stable cuts
• Suitable for medium to heavy steel turning

High, predictable cutting performance for tougher turning tasks

The combination of CVD-coated surface treatment and a tough T9225 carbide formulation provides high resistance to abrasive wear while keeping fracture toughness for interrupted cuts. This indexable insert is designed for productive machining in variable engagement conditions; the coating reduces built-up edge and thermal wear, extending tool life and supporting consistent cycle times. The result is fewer tool changes and improved process reliability in batch and jobbing environments.

Accurate fit and secure clamping reduce setup time

Built to the ISO CNMM190612 standard, the insert's rhombic 80° geometry and cylindrical hole allow straightforward seating in compatible holders. Compatibility is determined by form, clearance, tolerance class, fastening, size and thickness, so matching the insert to the correct external holder avoids chatter and uneven wear. The 0° clearance specification and 6.35 mm thickness deliver predictable positioning; correct seating ensures repeatable indexability and stable tooloverhang for improved dimensional control.

Controlled chip formation for safer machining and better finishes

The single-sided chipbreaker is tuned for steel applications and helps break and evacuate chips reliably under medium to heavy cuts. Effective chip control reduces the risk of entanglement and contributes to a cleaner working area, while also supporting a consistent surface quality on the workpiece. With a 1.2 mm nose radius, the insert balances edge strength and surface finish, offering improved component appearance without compromising edge stability.

Durable substrate and grade selection for lower total machining cost

Manufactured from solid carbide and specified in the T9225 universal grade, this insert is intended for robust universal performance across a wide steel spectrum. The CVD coating combined with the grade's toughness reduces flank and crater wear under varying cut conditions, which translates into longer in-service life and better cost per part. For operations with occasional interruptions or variable engagement, this choice reduces scrap risk and supports steady production output.

FAQ

Which workpiece materials are best suited to this insert?
The CNMM190612 Tungaloy insert in grade T9225 is primarily intended for medium-to-heavy machining of steel, offering a balance of toughness and wear resistance for variable cutting conditions.

Is the insert compatible with standard CNMM holders?
Yes, the CNMM190612 geometry conforms to ISO standards; compatibility requires a matching holder for form, fastening and tolerance class to ensure correct seating and clamping.

How does the single-sided chipbreaker affect machining?
The single-sided chipbreaker on this insert promotes reliable chip control during steel turning, improving evacuation and helping to maintain surface finish while reducing the likelihood of chip-related interruptions.

Can this insert handle interrupted cuts or roughing?
The T9225 carbide grade is described as a robust universal grade suitable for changed engagement conditions and light interruptions, making it appropriate for many roughing and semi-finishing scenarios.

What are the fixing and indexing features of the insert?
The insert includes a cylindrical hole for screw retention and is indexable according to ISO CNMM dimensions; correct clamping and torque are essential for repeatable performance.
