CNMG 120408 GT9530 CNMG turning insert — coated cermet, 0.8 mm radius — Tungaloy
The CNMG120408 GT9530 is an ISO-series rhombic turning insert intended for finishing and light universal turning of steel, offering improved surface quality and extended service life.
- Coated cermet GT9530 for stable finishing
- 0.8 mm corner radius for precise edge strength
- Double-sided chipbreaker for consistent chip control
- ISO CNMG 120408 rhombic insert with hole
- 4.76 mm thickness for robust mounting
Precise finishing and durable cutting performance
The GT9530 grade is a coated cermet developed for wear resistance in finishing to light universal turning of steel, delivering a reliable balance between surface quality and lifetime. In practice, the fine-grained cermet coating stabilises the cutting edge at low to moderate feeds, which results in a smoother surface finish and fewer reworks. The relatively low tendency to built-up edge under stable cutting conditions contributes directly to longer tool life and predictable performance, improving process efficiency on repetitive production runs.
Compatibility and secure clamping for dependable process security
ISO conformity of the rhombic insert means compatibility is determined by insert shape, relief angle, tolerance class, fastening method, size and thickness; these factors must match the selected holder and clamp set. The insert is supplied with a cylindrical hole for secure mounting and is designed to work with standard external holders or boring bars for ISO CNMG geometry. For reliable seating and repeatability, check holder specifications against the insert's 4.76 mm thickness and 0° relief to ensure correct clearance and clamping torque.
Controlled chipflow and edge geometry that reduce cycle interruptions
The double-sided chipbreaker integrated into this grade supports consistent chip formation across finishing cuts, reducing the risk of entanglement and improving surface consistency. The 0.8 mm corner radius increases edge strength without sacrificing the fine finish required in precision turning, lowering the likelihood of premature edge failure. These features together aid in maintaining uninterrupted production, minimise the need for frequent tool changes and contribute to predictable machining costs over time.
Practical selection advice for everyday turning tasks
Choose the double-sided chipbreaker and the GT9530 grade when the priority is surface finish and stable, repeatable operation on steel under steady clamping. For heavier interrupted cuts or unstable setups, consider a different geometry or a tougher grade; for internal turning ensure compatibility with the selected boring bar and the required entry angle. The typical system comprises the ISO insert, a matching external holder or boring bar, an appropriate clamp set and spare screws for quick replacement and inventory management.

FAQ
What materials is this insert best suited for? The GT9530 coated cermet is optimised for cutting steel in finishing and light universal turning tasks, providing improved surface quality and longer life under stable conditions.
How does the insert mount in a holder? The CNMG120408 design features a cylindrical hole and a standard ISO form; it requires a compatible holder with matching pocket dimensions, clamp set and screw to ensure repeatable seating.
Can this insert be used for internal turning? Yes, the geometry and thickness permit use in boring bars for internal turning, provided the bar is specified for ISO CNMG inserts and offers the correct clearance for the 0° relief.
What advantage does the double-sided chipbreaker offer? The integrated double-sided chipbreaker promotes consistent chip control during finishing cuts, reducing interruptions and supporting a stable surface finish.
How should the corner radius influence cutting parameters? The 0.8 mm corner radius gives enhanced edge strength for fine finishes; feeds and depths of cut should be selected to balance surface quality and tool life according to machine rigidity and workpiece stability.
