DNMG 110408 NS9530 Tungaloy indexable turning insert – cermet finishing, 55°

DNMG110408 NS9530 Tungaloy-Wendeplatte is an ISO-standard indexable insert for precision external and internal turning, optimised as a finishing grade for steel components.

• Cermet finishing grade NS9530
• Sharp edge for superior surface finish
• ISO DNMG geometry, 55° cutting angle
• Double-sided chipbreaker, cylindrical hole

Achieve superior surface quality with a cermet finishing grade

The NS9530 grade is an uncoated cermet developed for low cutting forces and a very sharp cutting edge, making it ideal for finishing operations on steel under continuous cutting conditions and small depths of cut. Cermet materials combine a ceramic matrix with metallic binders to offer excellent wear resistance while maintaining edge sharpness; the result is a noticeably improved surface finish and reduced need for secondary machining. For production environments where consistent part appearance and tight tolerances matter, this finishing insert supports reliable process outputs and fewer rework cycles.

Reliable fit and clamping for repeatable turning results

Manufactured to ISO standards, the rhombic DNMG shape with a 55° cutting geometry and a 0° clearance angle ensures predictable engagement with compatible holders. Compatibility is determined by a combination of form, clearance angle, tolerance class, clamping method, size and thickness, so correct holder selection is essential for stability and tool life. The insert features a cylindrical hole for secure fastening and a thickness of 4.76 mm, providing the mechanical support required for consistent repeatability in batch production. Specifying the correct holder and clamping set-up reduces vibration and contributes directly to dimensional accuracy.

Improved chip control and economical finishing performance

The insert’s double-sided chipbreaker promotes controlled chip formation during continuous cuts, easing chip evacuation and protecting the workpiece surface. A corner radius of 0.8 mm balances edge strength with finishing capability, delivering a stable cutting edge that minimises micro-chatter while preserving a fine surface texture. Using an uncoated cermet for finishing delivers lower friction at the cutting edge and resistance to abrasive wear, which together support longer effective life in finishing cycles and more predictable replacement intervals — an economic benefit in high-volume turning operations.

Practical application notes for turning steels

Designed primarily for turning applications on steel, this insert is best applied where continuous cutting and small depths of cut are typical. Choose the appropriate chipbreaker and grade variant to match workpiece material, required surface quality and machine/fixture rigidity. For internal and external turning, ensure the selected holder matches the DNMG form factor and the insert’s dimensions: size 11 with a plate thickness of 4.76 mm and a 0.8 mm corner radius. Where machining conditions are less stable or interrupted, consider alternative grades or cutting parameters to avoid edge chipping and preserve the sharp cermet cutting profile.

FAQ

What materials is this insert designed for?
The DNMG110408 NS9530 insert is formulated as a finishing grade for steel; the NS9530 cermet excels in continuous cutting and small depths of cut on steel workpieces.

How does the corner radius affect performance?
A 0.8 mm corner radius provides a balance between edge strength and surface quality, helping to maintain a sharp edge while reducing the risk of chipping during finishing passes.

Is this insert compatible with standard DNMG holders?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and plate thickness; check these parameters against the DNMG110408 dimensions before use.

What benefits does the uncoated cermet bring compared with coated carbide?
Uncoated cermet like NS9530 offers superior edge sharpness and low cutting forces for finishing operations, resulting in improved surface finish and predictable wear in continuous cuts.

Can this insert be used for both internal and external turning?
Yes, the insert is suitable for both external and internal turning when paired with an appropriate holder and correct machining parameters.
