CNMG120412 GT9530 Tungaloy turning insert — coated cermet, 1.2 mm radius

The CNMG120412 GT9530 is an ISO-standard rhombic turning insert engineered for finishing and light general-purpose turning of steel.

• Coated cermet grade GT9530
• Superior surface finish and longer life
• 80° rhombic CNMG cutting geometry
• Double-sided chipbreaker with centre hole

High-precision finishing and longer tool life

The coated cermet grade GT9530 delivers a measurable advantage where surface integrity matters. Designed as a wear-resistant finishing to light universal grade, the material combination reduces flank wear and supports a more consistent surface finish under stable cutting conditions. The coating stabilises the cutting edge and contributes to longer tool life, especially on continuous or well-supported turning operations. For production settings that prioritise repeatable finishing results, this grade balances performance and economy.

Stable cutting geometry for reliable turning performance

The rhombic CNMG form with an 80° included angle and a 1.2 mm corner radius is aimed at controlled cutting forces and predictable chip flow. The insert’s double-sided chipbreaker and cylindrical hole improve clamping security and allow indexable use of both cutting edges, lowering per-edge cost. Compatibility with holders is governed by form, clearance angle (0°), tolerance class, clamping type, size and thickness; ensuring correct pairing with ISO-standard external holders or boring bars secures process stability and reduces the risk of seating or run-out errors.

Seamless system integration and productive machining

This ISO-series insert is intended to be used as part of a complete system comprising the indexable insert, a matching external holder or boring bar, shim/clamping kit and replacement screws. The carbide substrate and coated surface make it suitable for finishing and light universal turning of steel, offering good economy in medium- to high-volume batches where edge life and repeatable quality matter. Clear labelling and ISO designation streamline inventory management and reordering, while the robust geometry supports consistent results in both external and internal turning tasks.

FAQ

Which materials is this insert intended for?
The CNMG120412 GT9530 insert is formulated primarily for steel machining, offering wear resistance and surface quality suited to finishing and light universal turning.

What cutting geometry and edge radius does the insert offer?
This indexable insert features an 80° rhombic geometry with a 1.2 mm corner radius, designed to balance edge strength and surface finish.

Is the insert single- or double-sided and how is it secured?
The CNMG120412 GT9530 is double-sided with a central cylindrical hole, enabling indexed use of both edges and secure clamping in compatible ISO holders.

How does one ensure compatibility with toolholders?
Compatibility depends on form, clearance angle, tolerance class, clamping type, size and thickness; matching the ISO designation and these parameters with the chosen holder ensures correct seating and process reliability.

Can the insert be used for internal turning as well as external turning?
Yes, the ISO-standard CNMG geometry and the GT9530 finishing grade are suitable for both external and internal turning when used with an appropriate holder or boring bar.
