DPMT 11T304 NS9530 — turning insert, rhombic 55° / 0.4 mm radius (Tungaloy)

The DPMT11T304 NS9530 is an ISO-standard indexable insert engineered for precision external and internal turning, delivering a fine surface finish on steel with low cutting forces.

• ISO-standard rhombic insert, 55° geometry
• NS9530 cermet for fine finishing
• 0.4 mm corner radius for precise contours
• Cylindrical hole with 40°–60° countersink

Improve finishing quality with a sharp cermet grade

The NS9530 grade is an uncoated cermet developed for finishing steel where a sharp cutting edge and low cutting forces are priorities. Its composition reduces built-up edge formation and supports a continuous cutting regime, which helps achieve consistent surface roughness even at small depths of cut. For applications that demand minimal tool marks and repeatable part quality, this grade provides a predictable balance between wear resistance and edge sharpness. The combination of a rhombic 55° geometry and a 0.4 mm corner radius permits precise contouring while limiting radial cutting forces, leading to improved dimensional stability on turned components.

Secure clamping and ISO compatibility for hassle-free integration

Designed as an ISO indexable insert, the component fits common holders when the form, relief angle, tolerance class, clamping method, size and thickness match. The insert’s cylindrical hole with a single-sided countersink (40°–60°) ensures reliable centring and repeatable seating in compatible toolholders. Using the correct clamping set-up reduces vibration and improves tool life, which increases process stability on production lines. Specifying holders and clamping hardware consistent with ISO norms simplifies tool inventory and shortens set-up times across different machines and shifts.

Practical selection and productivity advantages

Choosing this insert for finishing tasks on steel yields tangible productivity benefits: lower cutting forces reduce spindle load and permit steadier feeds, while the NS9530 grade's edge properties support longer intervals between tool changes in continuous operations. For shops seeking to standardise consumables, the ISO-DPMT form offers a versatile option for both external and internal turning. When deciding on insert usage, pair the grade with appropriate feeds and speeds for fine finishing; small adjustments to depth of cut and feed rate typically produce immediate improvements in surface quality and cycle time.

FAQ

What materials is this insert suitable for?
The DPMT11T304 NS9530 insert is specified as a finishing grade for steel, offering low cutting forces and a sharp edge suited to fine turning operations.

Can the insert be used for internal turning as well as external turning?
Yes—this ISO rhombic geometry is suitable for both external and internal turning when matched with the appropriate holder and clamping configuration.

How does the NS9530 cermet grade differ from coated carbide grades?
NS9530 is an uncoated cermet optimised for sharpness and surface finish; it typically produces lower built-up edge and excels on continuous cuts and small depths of cut compared with some coated carbide grades that prioritise wear resistance.

What does the 0.4 mm corner radius mean for part finish?
A 0.4 mm corner radius provides a balance between fine surface finish and corner strength, enabling precise contours while maintaining edge stability during finishing passes.

Which holder features ensure compatibility with this insert?
Compatibility is determined by insert form, relief angle, tolerance class, clamping method, size and thickness; the insert’s cylindrical hole and countersink (40°–60°) help ensure correct seating in compliant holders.
