CNMG 120404 GT9530 — ISO turning insert for precision turning by Tungaloy

CNMG120404 GT9530 is a coated cermet indexable insert designed for finishing and light universal turning of steel components

• CNMG geometry 80° rhombic insert
• Coated cermet GT9530 for long life
• Double-sided chipbreaker for stable cutting
• Fits ISO holders with cylindrical hole

Improved surface quality with wear-resistant grade

The GT9530 coating on a coated cermet substrate is optimised for finishing operations where consistent surface quality and repeatable results are required. The grade delivers reduced flank wear in stable clamping and machining conditions, which translates into fewer tool changes and a more predictable production rhythm. For external and internal turning, the geometry and chip control reduce vibration and support better dimensional stability at the machined surface.

Greater productivity through reversible cutting edges

A double-sided chipbreaker and rotatable geometry make the insert cost-effective: two usable cutting edges per side extend service intervals and lower tooling costs per part. The 0.4 mm corner radius balances edge strength and surface finish, permitting moderate depths of cut without sacrificing edge life. Designed as an ISO plate, the insert allows quick indexation and consistent tool reuse, increasing uptime and throughput on turning centres and lathes.

Straightforward integration into ISO tool systems

Compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness; this ISO CNMG120404 format is widely supported across standard external holders and boring bars. Key dimensions include a 12 mm inscribed size, 4.76 mm thickness and an 80° diamond form with a cylindrical hole for secure clamping. These clear numeric values help engineers verify fitment and minimise trial-and-error during tool setting and programme qualification.

Practical guidance for workshop use and process stability

For finishing steel components, select the GT9530 grade and the appropriate chipbreaker variant to match rigidity and feed strategy; the chipformer reduces the risk of entangling chips and helps maintain a steady cutting force. If machining conditions are less stable, consider reducing feed or adapting holder support to retain the expected surface result and tool life. Technical advice is available to assist in choosing the matching holder, clamping set and replacement screws for system readiness.

FAQ

Which materials is this insert intended for?
The GT9530 grade is formulated for steel finishing and light universal turning; the coated cermet construction emphasises wear resistance and improved surface quality for stable machining conditions.

Is the insert reversible and cost-efficient?
Yes — the CNMG120404 GT9530 Tungaloy insert features a double-sided chipbreaker, allowing multiple indexable edges and extended tool life; refer to SKU TUN6707274 for ordering and inventory.

How to check holder compatibility for the insert?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; ensure the holder matches the CNMG geometry, 12 mm size, 4.76 mm plate thickness and the cylindrical hole arrangement.

What surface finish can be expected with this grade?
Under stable clamping and cutting conditions, the coated cermet GT9530 provides a consistently good surface finish suited to finishing operations while also offering longer tool life than standard uncoated grades.

Can this insert be used for internal turning tasks?
Yes — the geometry and chip control make the insert suitable for both external and internal turning; select an appropriate holder or boring bar that secures the plate with the correct clamping and clearance.
