DNMG150408 AT9530 Tungaloy – ISO rhombic turning insert, 55° lead angle

DNMG150408 AT9530 Tungaloy is an ISO rhombic indexable insert designed for fine and light turning operations, optimised for achieving excellent surface quality on steel.

• Cermet coating AT9530 for fine finishing
• ISO rhombic DNMG150408 geometry, 55°
• Double-sided chipbreaker for reliable chips
• Cylindrical hole mounting, precise fit

Superior finishing performance for steel turning

The coated cermet AT9530 substrate is engineered for finishing and light cuts on steel, delivering a noticeably improved surface finish compared with standard carbide grades. Cermet combines ceramic hardness with metallic toughness to reduce built-up edge and enable stable cutting at finishing feeds. This results in fewer rework cycles and a more predictable part appearance, especially when surface integrity is critical.

Stable wear behaviour and dependable chip control

The insert’s double-sided chipbreaker promotes consistent chip formation during both external and internal turning, helping to avoid interruptions caused by erratic chips. The coating and substrate combination encourage even wear across the cutting edge, extending usable edge life and maintaining dimensional consistency over multiple passes. For operations where repeatability and minimal variation are required, this insert provides dependable performance.

Precision fit and straightforward holder compatibility

Manufactured to ISO dimensions, the rhombic DNMG150408 geometry and central cylindrical hole enable accurate locating in matching indexable holders. Compatibility with a given holder depends on form, clearance angle, tolerance class, fastening method, size and thickness; selecting the correct clamping set and replacement screws ensures secure mounting and repeatable positioning. The standardised form simplifies inventory and changeover in mixed-operation environments.

Controlled geometry for finishing cuts

Key dimensions such as the 0° clearance angle, 0.8 mm corner radius and 4.76 mm plate thickness make this insert particularly suited to light cuts where surface quality and edge finish matter. The 55° lead angle balances cutting forces and accessibility, offering a compromise between strength and fine-detail machining. When paired with a suitable external holder or boring bar and appropriate cutting parameters, the insert reduces vibration and supports consistent part quality.
