RCMM1204M0-61 NS9530 Tungaloy turning insert — uncoated cermet for finishing

RCMM1204M0-61 NS9530 is an ISO-compliant turning insert designed for fine finishing operations on steel, optimised for continuous cuts and small depths of cut

• ISO-compliant round insert, secure cylindrical hole
• Uncoated cermet NS9530 for superior finish
• 7° clearance angle for low cutting forces
• Ideal for continuous finishing of steel

Consistent surface quality from an uncoated finishing grade

The uncoated cermet NS9530 is formulated for finishing applications where high surface finish and low cutting forces are paramount. With a naturally sharp edge, this grade reduces built-up edge and vibration in continuous-cut conditions, which translates into fewer secondary operations and less time spent on polishing. For production runs where component appearance and dimensional consistency matter, the insert’s combination of a sharp cutting edge and stable edge retention supports predictable results on a range of steels, especially when using modest depths of cut and controlled feeds.

Reliable fit and system compatibility for secure clamping

This ISO-indexed insert is designed for use in a complete system comprising an external holder or boring bar, a supporting shim or clamp and the correct fastening screw. Compatibility is determined by shape, relief angle, tolerance class, fastening method, size and thickness; the round form with a cylindrical hole ensures positive seating and repeatable clamping in matched holders. The specified 7° relief angle reduces rubbing and helps maintain low cutting forces, while the standard format simplifies tool inventory management and holder selection across the shop floor.

Durable substrate and predictable cutting behaviour

The body is produced with a cemented carbide substrate that provides structural support and vibration resistance, while the cermet cutting grade performs the cutting action. This combination yields a stable cutting edge and good wear characteristics in finishing tasks, particularly on steels where thermal and mechanical loads are moderate. The insert’s geometry and the choice of chipbreaker 61 support consistent chip formation under the recommended continuous-cut conditions, helping to maintain process stability and extend effective index cycles.

Practical advice for integration and tool selection

For reliable results, match the insert’s NS9530 finishing grade and chipbreaker 61 to the workpiece material and the intended stability of the set-up. Use holders that conform to the ISO form and tolerance for the RCMM series to guarantee seat accuracy and clamp integrity. When switching from roughing grades, reduce feed slightly and confirm surface quality before full production; this approach leverages the insert’s low cutting-force characteristics and preserves the sharp edge for longer runs. If further guidance is required on holder selection or cutting parameters, application-specific consultation is available.

FAQ

Which materials is this insert suited for?
The RCMM1204M0-61 with NS9530 is optimised for steel finishing; its uncoated cermet grade provides low cutting forces and excellent surface quality on a wide range of steels.

How does the round form and cylindrical hole affect clamping?
The round insert with a cylindrical hole ensures concentric seating and stable clamping in compatible ISO holders, improving repeatability and reducing the risk of misalignment.

What performance benefits does NS9530 offer compared with coated grades?
As an uncoated cermet, NS9530 offers a very sharp cutting edge and reduced tendency for built-up edge in finishing applications, which yields superior surface finish and consistent dimensional results under continuous-cut conditions.
