DCMT 11T304 NS9530 ISO turning insert – Tungaloy, uncoated cermet for finishing

The DCMT11T304 NS9530 is an ISO rhombic turning insert designed for finishing operations on steel, offering a sharp cutting edge and a geometry optimised for continuous cuts and small depths of cut.

• ISO rhombic insert DCMT 11T304 format
• Uncoated cermet grade NS9530 for fine finishing
• 0.4 mm nose radius for precise surface finish
• 7° clearance angle and cylindrical hole seating

Optimised finishing performance for steel components

The NS9530 grade is supplied as an uncoated cermet, developed for low cutting forces and a sharp cutting edge that improves surface appearance in finishing stages. The result is reduced need for secondary operations and consistent part quality when machining steels. Because the grade is tailored for continuous cutting and small depths of cut, predictable tool life and surface integrity are achieved when feeds and speeds are matched to the alloy and rigidity of the setup. This focus on performance supports efficient production planning and fewer rework cycles.

Geometry and mounting that simplify setup and repeatability

The rhombic plate form with ISO designation ensures compatibility with standard turning holders; seating is provided via a cylindrical hole with a one‑sided countersink (40°–60°), and the compact 0.4 mm nose radius delivers a fine finish without sacrificing edge strength. The insert has a 7° clearance angle, thickness 3.97 mm and size 11, which together determine how the insert engages the workpiece and mate with clamping systems. Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; correct matching reduces vibration and promotes repeatable results.

Chip control, recommended use and material match

A single‑sided chipbreaker is provided for controlled chip formation during finishing passes. For steels, the combination of the NS9530 cutting material and the sharp edge geometry produces low cutting forces and improved surface roughness; this makes the insert especially suitable for components requiring tight surface specifications. Where intermittent cutting or interrupted cuts are expected, select a holder and parameters that maintain support at the cutting edge. Cutting conditions should be chosen conservatively for the best balance of finish and tool life.

System setup and operational benefits

A complete machining system is composed of the ISO insert, a compatible external holder or boring bar, a shim or clamping set and replacement screws. This ISO‑based approach simplifies inventory and replacement strategies and enables quick swaps during tool changes. Stable chip formation and the finishing orientation of the grade promote consistent part quality and machining reliability, supporting high first‑pass yields and less downstream inspection. When tool life is maximised by appropriate feeds and speeds, overall productivity and process stability are improved.

FAQ

What materials is this insert best suited for?
The DCMT11T304 NS9530 insert is formulated as an uncoated cermet grade for finishing steel, providing low cutting forces and an excellent surface finish when used under continuous cutting conditions.

How does the 0.4 mm nose radius affect surface finish?
A 0.4 mm nose radius delivers a balanced contact area that improves surface quality while maintaining edge strength; with the NS9530 grade, this helps to achieve finer finishes on turned components.

Which holders are compatible with this ISO insert?
Compatibility is determined by holder form, clearance angle, tolerance class, fastening, size and thickness; the insert is made to ISO standards for use with matching turning holders or boring bars.

Is this insert suitable for interrupted cuts?
The DCMT11T304 is optimised for continuous finishing cuts; for interrupted cutting, select a robust holder and adjust cutting parameters to ensure edge support and to protect the sharp cutting edge.

What is the correct seating for the insert?
The insert uses a cylindrical hole with a one‑sided countersink (40°–60°) for seating; ensure the clamping set and replacement screws conform to the holder specifications for secure fixation.
