CNMG090404 NS9530 Tungaloy turning insert — finishing-grade uncoated cermet, 0° clearance, 80° approach

The CNMG090404 NS9530 is an ISO-standard rhombic turning insert designed for finishing operations in steel, offering a sharp edge geometry and low cutting forces for continuous cuts and small depths of cut.

• Finishing-grade uncoated cermet NS9530
• Sharp cutting edge for superior surface finish
• Rhombic CNMG geometry with 80° approach
• Double-sided chipbreaker with cylindrical hole

Higher-quality finishes with lower cutting forces

The uncoated cermet grade NS9530 is formulated for finishing in steel and produces a sharp cutting edge that reduces cutting forces and improves surface integrity. Cermet combines ceramic hardness with metallic toughness, which helps to maintain a fine edge during continuous turning. For operations where small depths of cut and consistent surface roughness are priorities, this insert gives a clear advantage in producing ready-to-measure surfaces with fewer downstream processes. The result is more consistent component quality and reduced rework.

Stable geometry for predictable machining results

The rhombic CNMG form with an 80° approach and 0° clearance provides a neutral, predictable cutting geometry for finishing passes. Neutral clearance supports minimal interference at the flank contact and helps to avoid chatter when the workholding and tool overhang are correctly controlled. Compatibility with the selected holder is determined by the insert shape, clearance, tolerance class, fastening method, size and thickness, so matching the CNMG geometry to a rigid external holder or boring bar is essential for repeatable performance and dimensional stability.

Efficient indexing and secure clamping reduce downtime

Featuring a double-sided chipbreaker and a cylindrical hole for positive clamping, the insert enables economical indexing and secure fixation in standard ISO-compatible holders. Reversible geometry doubles the number of available cutting edges, lowering tooling costs per component and shortening changeover time. The plate thickness of 4.76 mm and a 0.4 mm corner radius contribute to mechanical stability during finishing cuts, helping to preserve edge integrity and reduce vibration in long production runs.

Process guidance for turning steel components

Designed primarily for external and internal turning in steel, the insert performs best with continuous cuts and modest cut depths; choose the chipbreaker and grade in line with material, operation and machine/tooling stability. For best results, combine the insert with a rigid holder, correct clamping torque and a stable setup. The ISO-standard design simplifies integration into existing tooling systems and makes inventory management straightforward for production environments focused on finishing accuracy.

FAQ

What materials is this insert best suited for?
The CNMG090404 NS9530 is optimised for finishing in steel; the NS9530 cermet grade delivers a sharp edge and low cutting forces for high-quality surface finishes.

How does the double-sided chipbreaker impact productivity?
A double-sided chipbreaker provides multiple indexing positions on the insert, lowering tooling costs and reducing changeover frequency for the CNMG090404 NS9530.

Is this insert compatible with standard CNMG holders?
Yes — the insert follows ISO plate geometry; compatibility depends on holder form, clearance, tolerance class, fastening, size and thickness, so confirm fit with the chosen holder.

What is the significance of the 0° clearance?
A 0° clearance represents a neutral relief geometry suited to finishing when combined with a rigid setup; it helps maintain a consistent flank contact and surface finish under controlled conditions.

How many usable cutting edges are available on the insert?
The reversible CNMG form with double-sided chipbreaker offers multiple usable edges; the exact count depends on the indexing scheme used on the Tungaloy CNMG090404 NS9530.
