DPMT 11T308 NS9530 — ISO turning insert for finishing, uncoated cermet, Tungaloy

DPMT11T308 ISO turning insert designed for finishing operations in steel, offering a sharp edge and low cutting forces for continuous, high-precision turning.

• Uncoated cermet finishing grade NS9530
• Sharp cutting edge for superior surface finish
• 11° relief and 0.8 mm corner radius
• Single-sided chipbreaker with mounting hole

Higher-quality finishes with lower cutting forces

This turning indexable insert is built around the NS9530 uncoated cermet grade, which provides a notably sharp cutting edge and reduced cutting resistance. The result is a consistent surface finish improvement during light, continuous cuts, particularly in steel machining. The combination of a low cutting force and the fine edge geometry reduces vibration at the tool–workpiece interface, which enables more predictable part quality and less rework.

Reliable compatibility and easy holder selection

The insert follows ISO specifications, so compatibility with holders depends on shape, relief angle, tolerance class, fastening and thickness. The 11° relief and rhombic form are suited to common external and internal turning holders; correct clamping and the matching support pad are essential for secure mounting. Where adapters or clamping sets are required, the ISO standardisation simplifies selection and ensures the insert can be replaced without altering the machining set-up.

Precise geometry for repeatable performance

With a 0.8 mm corner radius and a plate thickness of 3.97 mm, the geometry of this insert gives a balance between edge strength and the ability to produce fine surface finishes on small depths of cut. The single-sided chipbreaker is tuned for finishing feeds and continuous cuts, promoting short, consistent chips and reducing the risk of built-up edge. The substrate is a cemented carbide base that supports the cermet cutting top, enabling dimensional stability across longer runs.

Practical applications and handling guidance

Intended primarily for turning (external and internal), the insert is most effective in finishing passes on steel where a sharp edge and low cutting forces are priorities. For best results, choose feeds and speeds aligned with finishing practice and ensure coolant and chip evacuation are appropriate for continuous cutting. The insert is supplied with a cylindrical mounting hole and one-sided countersink (40°–60°) for standard fastening systems and simple, repeatable index changes.

FAQ

What materials is this insert best suited to machine?
The DPMT11T308 NS9530 from Tungaloy is a finishing grade optimised for steel; the uncoated cermet top delivers a sharp edge and good surface quality in continuous turning.

Which machines or holders accept this ISO insert?
ISO-compatible turning holders that match the rhombic shape, 11° relief and 3.97 mm thickness will accept the DPMT11T308; check holder tolerance class and clamping method for secure mounting.

How does the chipbreaker affect finishing operations?
The single-sided chipbreaker is designed to produce short, consistent chips during finishing cuts, improving surface integrity and reducing the chance of built-up edge when using the NS9530 grade.

Is the insert suitable for interrupted cuts or heavy roughing?
This insert is a finishing grade and is optimised for continuous, light depth-of-cut turning; for interrupted cuts or heavy roughing, a more robust grade or geometry is recommended.
