DCMT 11T302 NS9530 Wendeplatten - Tungaloy

The precise 0.2 mm corner radius combined with the NS9530 uncoated cermet grade and ISO rhombic geometry results in reliably low cutting forces and superior surface finish for finishing operations; order directly via Metav Werkzeuge or contact our consultants for application advice.

DCMT 11T302 NS9530 Tungaloy turning insert — ISO rhombic, finishing for steel

The DCMT11T302 NS9530 Tungaloy is an ISO rhombic indexable turning insert engineered for finishing cuts on steel, offering a sharp cutting edge and stable chip formation.

• ISO rhombic insert, compatible with standard holders
• NS9530 uncoated cermet for fine surface finish
• 0.2 mm corner radius for precise radiusing
• Cylindrical hole with countersink for secure clamping

Engineered for a finer surface and lower cutting forces

The combination of the NS9530 uncoated cermet grade and a sharp edge geometry is aimed at finishing and light machining, delivering a consistently improved surface finish with reduced cutting forces. The cutting material is optimised for continuous cuts and small depths of cut, which reduces vibration and the risk of built-up edge. This leads to more predictable part quality and helps maintain tighter tolerances on turned components.

Geometry and clamping that reinforce process reliability

The ISO-conforming rhombic shape and the insert’s central cylindrical hole with a single-sided countersink (40°–60°) provide reliable, repeatable clamping in compatible holders. The 55° approach angle contributes to controlled cutting engagement while the standard form and tolerance class ensure compatibility across many commercially available holders, simplifying tool inventory and setup.

Setup advantages that increase machining stability

A nominal corner radius of 0.2 mm combined with a 7° clearance angle and a plate thickness of 3.97 mm provides a balance between edge strength and the fine finishing required for steel components. The one-sided chipbreaker is tailored for finishing, shaping chips predictably and helping avoid irregular chip formation. These features reduce the need for frequent adjustment and support stable cycle times in production environments.

Tailored for finishing steel with predictable results

Designed primarily for turning of steel, this insert excels in operations where surface quality and dimensional consistency matter. The uncoated cermet composition is chosen to produce low friction during cutting and to promote a stable cutting edge under continuous-feed conditions. The result is lower rework rates and a smoother downstream process for parts that demand high finishing standards.

FAQ

What materials is this insert suited for?
The DCMT11T302 NS9530 Tungaloy turning insert is designed primarily for finishing on steel; the NS9530 uncoated cermet provides low cutting forces and a fine surface finish for continuous cuts.

Which holders are compatible with this ISO insert?
Compatibility is determined by insert form, clearance angle, tolerance class, attachment method, size and thickness; the rhombic ISO form and central hole support standard external holders and boring bars.

What advantages does the NS9530 grade offer in finishing?
NS9530 is an uncoated cermet grade engineered for sharp cutting edges, low cutting forces and high surface quality, particularly effective in continuous-feed finishing operations.

How does the chipbreaker affect performance?
The one-sided chipbreaker is tuned for finishing cuts to shape chips predictably, reducing the risk of irregular chip formation and supporting stable machining conditions.

Is the insert suitable for interrupted cuts or heavy roughing?
This insert is optimised for finishing and small depths of cut; for heavy roughing or heavily interrupted cuts, a grade and geometry designed for higher toughness would be more appropriate.
