DNMG150408 GT9530 ISO turning insert — Tungaloy, coated cermet, 0° clearance

The DNMG150408 GT9530 is an ISO rhombic turning insert engineered for external and internal turning applications where high surface quality and longer tool life under stable conditions are required.

• Coated cermet grade GT9530
• 0° clearance for fine finishing
• Rhombic 55° geometry, 15 mm size
• Cylindrical hole for secure clamping

Durable cermet finishing for reliable surface quality

The coated cermet designation of this insert combines ceramic hardness with metallic toughness to deliver a superior surface finish on steel components. Cermet cutting materials reduce built-up edge and are especially effective in finishing passes where consistent geometry and low cutting forces are priorities. The GT9530 grade is optimised for wear resistance and longer tool life under stable machining conditions, which translates into fewer indexings and less unplanned downtime. By choosing this grade, shops achieve predictable results without sacrificing component finish.

Geometry and clamping that ensure repeatable accuracy

A rhombic 55° geometry provides a versatile approach angle for both light turning and profiling, while the 0° clearance promotes minimal radial engagement for fine finishing operations. The insert’s cylindrical hole supports precise and secure clamping with standard ISO holders; compatibility depends on matching form, clearance angle, tolerance class, fixing method, size and thickness. Proper pairing of insert and holder reduces vibration and runout, improving surface consistency and protecting the cutting edge from premature wear.

Productivity advantages from indexability and chip control

The double-sided design with a double-sided chipbreaker permits economical indexability and multiple usable cutting edges per insert, increasing the effective life of each part. In a production environment this reduces tool change frequency and tooling cost per component. The insert is part of a system consisting of the ISO indexable plate, a suitable external holder or boring bar, a support/shim set and replacement clamping screws; this modular approach simplifies setup and helps maintain high process reliability on batch and serial operations.

Best applications and recommended use for machining steel

This grade is intended primarily for finishing to light semi-finishing on steel, where a good surface and predictable wear behaviour are required. Selection of chipbreaker and grade should match the workpiece material, machining method and machine/tool stability. The insert performs well under steady cutting conditions and with appropriate coolant strategies; when higher roughing forces or interrupted cuts are present, a different grade or geometry may be more suitable. For external and internal turning, the combination of geometry and coated cermet material is particularly effective at producing fine surfaces with consistent repeatability.

FAQ

What materials is this insert best suited to machine?
The DNMG150408 GT9530 insert is optimised for finishing and light universal work on steel, offering good surface quality and extended life when used under stable cutting conditions.

How does the GT9530 coating improve performance?
The GT9530 coated cermet reduces wear and built-up edge compared with uncoated grades, resulting in more consistent finishes and fewer indexings in finishing operations.

Is the insert compatible with standard ISO holders?
Compatibility is achieved by matching the insert form, clearance angle, tolerance class, fixing method, size and thickness; the DNMG150408 fits standard ISO rhombic holders designed for this geometry.

What advantages does the 0° clearance provide?
A 0° clearance minimises radial engagement for fine finishing passes, helping to produce a superior surface finish with reduced tendency for chatter under stable set-ups.

How does the double-sided chipbreaker affect productivity?
The double-sided chipbreaker allows multiple indexable edges and improved chip control, lowering tooling costs per part and reducing machine downtime for tool changes.
