CNMG 190612 T9225 turning insert by Tungaloy — CVD-coated carbide, rhombic 80° geometry

CNMG190612 T9225 Tungaloy insert designed for ISO-compliant turning of steel, offering a robust universal grade suited to interrupted and variable engagement conditions

• CVD-coated carbide grade T9225
• Suitable for medium to heavy steel turning
• Rhombic CNMG shape, 80° cutting angle
• Double-sided chipbreaker with cylindrical hole

Increased productivity with a robust universal grade

The combination of a CVD-coated surface and a specially formulated T9225 substrate delivers an excellent balance of wear resistance and toughness. This turning insert is intended for steel machining where variable cutting conditions or light interruptions occur; the coating reduces flank wear while the substrate provides impact resistance. As a result, stable tool life and fewer index changes can be expected, which translates into improved uptime and predictable process cycles for production lines.

Precision geometry for reliable chip control and repeatability

The rhombic CNMG geometry with an 80° cutting angle and 1.2 mm corner radius offers a versatile cutting profile that supports both external and internal turning tasks. The double-sided chipbreaker ensures consistent chip formation across typical feed ranges and contributes to surface integrity. Compatibility with ISO holders is determined by form, relief angle, tolerance class, fastening method, size and thickness, so correct clamping and match to the chosen holder are essential for reproducible results.

Clear technical advantages that reduce machining cost

Using a grade designed for the intended material mix reduces unplanned tool changes and scrap. The insert’s balanced combination of toughness and coating performance reduces edge chipping and adhesive wear, helping to maintain dimensional accuracy over longer tool life. In practical terms, this can lower component rework rates and shorten overall cycle time — measurable benefits when switching from a general-purpose grade to a targeted solution such as this.

Practical selection guidance and workshop integration

When specifying an insert for turning, select the chipbreaker and grade in line with the workpiece material, machining stability and intended feed/speed. The insert thickness of 6.35 mm, size 19 mm, and the presence of a cylindrical centre hole make the part easy to seat in common ISO clamping systems while maintaining rigidity. Where higher cutting speeds are required, confirm the holder and machine capabilities first; the combination of geometry and CVD coating supports a range of cutting parameters but works best when the overall system is balanced.

FAQ

What materials is this insert intended for?
The CNMG190612 T9225 insert is formulated for robust medium to heavy steel machining; the Tungaloy T9225 grade balances toughness and wear resistance for such applications.

Is the insert compatible with ISO tool holders?
Yes, the CNMG190612 follows ISO geometry; compatibility depends on holder form, relief angle, tolerance class, fastening and the insert thickness of 6.35 mm.

How does the chipbreaker affect performance?
The double-sided chipbreaker on this turning insert promotes consistent chip control and reduces the risk of built-up edge, improving surface finish and repeatability during turning operations.

Can this insert handle interrupted cuts?
The T9225 grade provides enhanced toughness suitable for light to moderate interruption; this makes the insert appropriate where cutting conditions vary or short interruptions occur.
