DCMT 11T302 NS9530 rhombic turning insert — Tungaloy, finishing grade

The DCMT11T302 NS9530 is an ISO-standard rhombic turning insert designed for high-quality finishing of steel in continuous cuts, offering a sharp cutting edge and low cutting forces.

• ISO rhombic form with 55° cutting angle
• Uncoated cermet finishing grade NS9530
• Corner radius 0.2 mm for fine surface finish
• Cylindrical hole with 40°–60° countersink

Consistent finishing performance for steel turning

The NS9530 uncoated cermet grade is formulated for finishing operations on steel, providing a sharp cutting edge and reduced cutting forces that favour continuous cuts and small depths of cut. This results in improved surface integrity and less burr formation compared with general-purpose grades. The insert’s geometry is developed to produce a stable cut with predictable wear behaviour, which supports process reliability and repeatable part quality in production environments.

Geometry and holder compatibility that simplify selection

The rhombic shape with a nominal 55° cutting angle and an effective relief angle of 7° ensures versatility for both external and internal turning where access and lead angle are critical. Compatibility with a given toolholder depends on the insert form, relief angle, tolerance class, clamping method, size and thickness; the ISO designation and dimensions make it straightforward to match the insert to standard external holders or boring bars. Clear knowledge of these parameters reduces setup time and helps avoid mismatches that compromise clamping or cutting performance.

Chip control and surface finish benefits

A single-sided chipbreaker combined with the fine 0.2 mm corner radius helps to produce narrow, well-formed chips and a high-quality surface finish. For continuous, stable cuts the chip shape encourages predictable evacuation and reduces the risk of re-cutting. In finishing applications the sharp edge geometry lowers cutting forces and heat generation, which contributes to dimensional stability and consistent part appearance across runs.

Practical selection and application advice

The insert is intended primarily for turning operations on steel where a high-quality finish is required; it is especially suitable for continuous machining and small-width cuts. When selecting the matching holder and cutting parameters, prioritise rigidity and firm clamping to exploit the finishing grade’s strengths. The insert designation and ISO series guidance aid selection for either external holders or boring bars. If further specification or cutting data is required, technical consultation is recommended to ensure optimal process settings for surface finish and tool life.

FAQ

Which materials is this insert recommended for?
The DCMT11T302 NS9530 is optimised as a finishing grade for steel; the NS9530 uncoated cermet provides a sharp edge and low cutting forces for continuous turning of steel components.

What does NS9530 mean in practice?
NS9530 identifies the uncoated cermet grade tailored for finishing; in use the NS9530 grade gives a finely honed edge that supports superior surface finish and controlled wear in light finishing cuts.

How important is holder selection for this insert?
Holder compatibility is essential: form, relief angle, tolerance class, clamping method, size and thickness determine correct fit — the ISO designation simplifies matching to standard turning holders or boring bars.

What chip control can be expected?
With its single-sided chipbreaker and sharp edge geometry, the insert produces narrow, well-formed chips under stable cutting conditions, aiding evacuation and consistent surface quality.

Is this insert suitable for internal turning as well as external?
Yes, the rhombic form and 55° cutting angle make the insert suitable for both external and internal turning where access and approach angles permit.
