CNMG120404 T9225 Turning indexable insert by Tungaloy — CVD-coated carbide, 80° rhombic

The CNMG120404 T9225 indexable insert is an ISO-format turning insert designed for robust medium-to-heavy steel machining, offering a universal, CVD-coated carbide grade for variable cutting conditions.

• CVD-coated carbide grade T9225
• Robust universal grade for medium–heavy steel
• CNMG 120404, 80° rhombic insert form
• Double-sided chipbreaker with 0.4 mm corner radius

High-performance cutting for variable steel operations

The insert’s CVD-coated carbide substrate and the T9225 grade combine hardness with enhanced toughness, enabling consistent performance in demanding turning tasks. This composition is engineered for medium-to-heavy steel machining where variable engagement or slight interruptions occur; the coating increases wear resistance while the substrate maintains edge stability. The net effect is a longer effective tool life and fewer unscheduled indexings, which supports predictable cycle times and reduces process variability on lathes and turning centres.

System compatibility and practical geometry advantages

Engineered to ISO dimensions, the ISO CNMG120404 format ensures broad holder compatibility where form, relief angle, tolerance class, fixing method, size and thickness match. The 80° rhombic shape and 4.76 mm thickness provide a stable seating and good edge strength; the cylindrical hole enables secure clamping with standard screws and clamps. The specified 0° relief angle suits many external turning set-ups and demands correct holder selection to secure the required cutting clearance. These measurable attributes simplify integration into existing tool systems and help planners verify fit before purchase.

Operational benefits: chip control, edge life and handling

The double-sided chipbreaker geometry offers reliable chip control across a range of feeds, while the 0.4 mm corner radius balances strength and surface finish to reduce chatter risk on less rigid set-ups. As an indexable solution, the insert minimises downtime by providing multiple usable edges and straightforward replacement. The robust universal grade supports operators facing mixed batch production, where one insert must cope with slightly varying cuts. For production managers, this translates into reduced tool inventory complexity and improved spindle uptime.

FAQ

Which materials is this insert suitable for?
The CNMG120404 T9225 insert is specified as a robust universal grade for medium-to-heavy steel machining and is optimised for variable engagement conditions.

How does the T9225 grade affect performance?
The T9225 CVD-coated carbide grade offers a combination of wear resistance and increased toughness, making the insert reliable under slightly interrupted cuts and fluctuating cutting conditions.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm corner radius provides a compromise between edge strength and surface finish, improving edge life while helping achieve a consistent surface quality in general turning tasks.

Is the CNMG120404 compatible with existing holders?
Compatibility depends on matching the ISO CNMG form, size, thickness, relief angle and fixing method; the CNMG120404 format follows ISO dimensions to ensure broad holder compatibility.
