DCMT 11T304 NS9530 — ISO turning insert for finishing (55°) — Tungaloy

DCMT11T304 NS9530 Tungaloy turning insert combines a rhombic ISO geometry with an uncoated cermet grade optimised for finishing on steel components

• ISO rhombic insert, 55° geometry
• Uncoated cermet grade NS9530
• 0.4 mm nose radius for fine finishes
• Single-sided chipbreaker, with hole

Consistent surface quality with low cutting forces

The uncoated cermet NS9530 is a finishing grade developed for continuous cuts on steel, delivering a sharp cutting edge and low cutting forces that reduce vibration and thermal loading. This results in improved surface integrity and reproducible results across batches. The insert’s 0.4 mm nose radius supports narrow depths of cut while producing fine surface finishes, making it suitable for external and internal turning where dimensional and cosmetic quality matter.

Reliable fit and secure clamping in ISO systems

The ISO rhombic shape and standardised designation ensure compatibility with holders that match form, clearance, tolerance class, fastening and thickness. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) for secure screw clamping, which simplifies replacement and reduces setup time. Defined dimensions and hole style support repeatable positioning and stable machining, so set-up effort is minimised and production runs remain predictable.

Application-focused material and chip control

As an uncoated cermet, the grade combines wear resistance with a sharp edge geometry tailored to finishing operations. The single-sided chipbreaker promotes controlled chip formation in continuous-cut conditions and small feed rates; this reduces the risk of built-up edge and helps maintain surface finish. The insert’s design makes it particularly effective for light-duty finishing passes on turned steel components where consistent part quality is required.

Practical handling, inspection and tool selection guidance

With a nominal thickness of 3.97 mm and a clearance angle of 7°, this insert integrates into common ISO turning systems without altering holder geometry. Selection of the correct chipbreaker and grade for the workpiece material and machining stability remains essential: choose this grade for continuous finishing on steel, and pair it with a stable external or internal holder to exploit its strengths. Regular inspection of edge condition and secure torque of the clamping screw will sustain performance and tool life.

FAQ

Which applications suit this insert best? The DCMT11T304 NS9530 Tungaloy insert is optimised for finishing in external and internal turning operations on steel, particularly where continuous cuts and high surface quality are required.

What does the NS9530 grade offer compared with standard carbide? The NS9530 uncoated cermet provides a sharper cutting edge and reduced cutting forces versus many carbides, improving surface finish and dimensional stability in finishing passes with small depths of cut.

How is the insert clamped in the holder? The insert features a cylindrical hole with a single-sided countersink (40°–60°) for screw clamping; this ensures secure, repeatable seating in compatible ISO holders.

Are there specific holder requirements for the rhombic DCMT geometry? Compatibility depends on holder form, clearance, tolerance class, fastening, size and thickness; a matching ISO rhombic external or internal holder is required for correct seat and performance.
