CPGT 090304 NS9530 CPGT — ISO turning insert for finishing, Tungaloy

CPGT090304 NS9530 — a rhombic ISO turning insert for finishing operations in steel, designed for continuous cuts and small depths of cut

• Rhombic ISO geometry for stable finishing
• Uncoated NS9530 cermet for sharp edges
• 0.4 mm corner radius for fine surface quality
• Cylindrical hole with single-side countersink (40°–60°)

Consistent finishing performance with minimal cutting forces

The NS9530 grade is specified as an uncoated cermet finishing material that delivers a sharp cutting edge and low cutting forces, which directly translates to improved surface finishes on steel. For finishing operations, reduced cutting forces mean less tool-induced vibration and better dimensional stability, so parts meet tolerance at the first pass. Where continuous cuts and small depths of cut are standard, this grade maintains edge integrity and produces consistently smooth surfaces, reducing downstream grinding or polishing effort.

Secure clamping and ISO compatibility for predictable production

Compatibility with toolholders depends on form, relief angle, tolerance class, clamping and plate thickness — all ISO‑defined dimensions ensure interchangeability across standard holders. The insert features a cylindrical hole with a single-side countersink (40°–60°) for secure axial and radial positioning, while the rhombic shape and 80° included angle give stable support in the pocket. Choosing holders and clamping sets that match these parameters minimises chatter and setup variability, increasing process reliability on batch or single‑piece production.

Material composition explained: why cermet works for finishing

Cermet is a ceramic‑metal composite optimised for fine finishes and edge retention at moderate cutting temperatures. The combination of a carbide body and an uncoated cermet top grade provides a balance between wear resistance and the ability to form a sharp edge. That balance results in extended life in finishing applications without the need for coatings that can blunt the initial edge. The 0.4 mm corner radius supports fine profile control while the 11° relief angle reduces rubbing on the flank face, lowering heat generation and preserving workpiece integrity.

Practical advantages in routine turning and recommended use

Designed for external and internal turning, this insert suits operations where surface integrity and repeatable dimensions matter. The single-sided chipbreaker style is intended for predictable chip formation in continuous cuts; combined with small depth of cut strategies, this reduces the risk of built-up edge and enhances throughput. For shops aiming to improve first‑pass yield and reduce rework, the geometry and grade provide an economical route to higher process stability and superior finish quality.

FAQ

What materials is this insert best suited for? This insert is a finishing grade optimised for steel; the NS9530 uncoated cermet is specified for fine surface finishes and low cutting forces when turning steel.

How does the hole and countersink affect clamping? The cylindrical hole with a single-side countersink (40°–60°) ensures secure location and clamping stability in compatible ISO holders, improving repeatability during turning.

Is the 0.4 mm corner radius suitable for profile work? A 0.4 mm corner radius balances profile fidelity and edge strength, making it appropriate where fine surface quality and dimensional control are required.

Can this insert be used for interrupted cuts? The NS9530 finishing grade and single-sided chipbreaker are primarily intended for continuous cuts and small depths of cut; interrupted cuts may accelerate wear and are not the primary recommendation.

Which holder parameters must match to ensure compatibility? Compatibility is determined by the insert form, relief angle (11°), tolerance class, clamping method, size and thickness (3.18 mm); matching these ISO parameters ensures proper fit and function.
