CNMG120408 120408 NS9530 Tungaloy – ISO turning cermet insert for finish turning

CNMG120408 NS9530 Tungaloy is an ISO‑standard rhombic insert designed for precision external and internal turning in steel, optimised for continuous cuts and fine surface finishes

• ISO CNMG geometry for standard holder compatibility
• NS9530 cermet for fine finishing of steel
• 80° rhombic shape with 0.8 mm corner radius
• Double-sided insert with cylindrical hole

Achieve superior surface finish with a finishing cermet grade

The NS9530 grade is an uncoated cermet developed for finish turning of steel where a sharp cutting edge and low cutting forces are priorities. Its composition and edge geometry reduce built‑up edge and promote a consistently fine surface finish, which is especially beneficial for continuous cuts and small depth‑of‑cut operations. For shops seeking repeatable part quality and reduced secondary operations, the fine‑grade cermet translates directly into measurable improvements in dimensional accuracy and visual appearance.

ISO geometry and robust system compatibility for predictable performance

The CNMG120408 insert follows ISO dimensions and a rhombic form with an 80° included angle, a 0.8 mm corner radius and a 0° clearance specification, facilitating straightforward integration with standard external holders or boring bars. The insert’s cylindrical hole and double‑sided design enable reliable clamping and economical edge indexing. Compatibility to a chosen holder depends on form, relief/clearance angle, tolerance class, fastening method, size and thickness — the insert is intended to work as part of a system comprising insert, appropriate holder, shim/clamping set and replacement screws.

Practical selection and machining advice for consistent results

As an uncoated finishing grade, this insert performs best in steady, continuous cuts on steel and delivers low cutting forces that support stable machining and longer holder life. It is less tolerant of heavy interruption; for operations with frequent entry/exit or heavy interrupted cuts, consider grades and chipformers that prioritise toughness. Selecting the correct double‑sided chipbreaker and matching the grade to the workpiece and process stability yields both improved surface integrity and cost efficiency through multiple indexable edges.

FAQ

What materials is this insert best suited for? The CNMG120408 NS9530 insert is optimised for steel and is specified as a finishing grade for continuous cuts delivering high surface quality.

Can the insert be used with standard ISO holders? Yes, the ISO‑compliant CNMG120408 geometry is designed for compatibility with standard external holders and boring bars when the holder matches form, clearance angle, tolerance class, fastening and size.

How many cutting edges does the insert provide? The double‑sided design of the CNMG120408 NS9530 Tungaloy insert (SKU 6998123‑Tungaloy) permits indexing to a fresh edge multiple times, improving economy per insert.

Is the NS9530 grade coated or uncoated? The NS9530 grade supplied in this insert is uncoated cermet, chosen for its sharp cutting edge and superior finish on steel.

Is this insert suitable for interrupted cuts? The CNMG120408 NS9530 Tungaloy insert performs best in continuous cuts and small depths of cut; for heavy interruptions a tougher, coated grade would generally be recommended.
