CCMT09T304 NS9530 Tungaloy indexable insert for turning — uncoated cermet, 7° clearance

The CCMT09T304 NS9530 is an ISO rhombic turning insert designed for finishing operations on Stahl, offering a sharp cutting edge and stable performance in continuous cut conditions.

• Uncoated NS9530 cermet for excellent surface finish
• Rhombic CCMT geometry with 80° cutting edge
• 7° clearance angle for low cutting forces
• 0.4 mm corner radius for precise finishing

High-quality finishing with low cutting forces

The uncoated NS9530 cermet grade is formulated for finishing on Stahl, providing a sharp cutting edge and reduced cutting resistance that together improve surface integrity. In continuous cutting conditions and with small depths of cut the material combination yields consistent dimensional results and low burr formation. The insert’s geometry is optimised for tight tolerances and superior surface quality, making it particularly suitable where a fine finish is the primary requirement.

Reliable fit and clear mounting parameters

Designed to the ISO CCMT specification, the insert’s compatibility with holders depends on form, clearance, tolerance class, fixing method, size and thickness. The rhombic shape and an 80° approach give versatility for both external and internal turning in common ISO holder systems. The plate thickness of 3.97 mm and the cylindrical hole with one-sided countersink (40°–60°) ensure secure clamping and repeatable seating, reducing downtime from repositioning and improving process stability.

Consistent process results and application guidance

A 0.4 mm corner radius supports precision finishing without compromising edge life in fine-feed operations, while the 7° clearance angle lowers cutting forces and minimises rubbing. As a finishing grade, the insert is best matched with small depths of cut and steady feed to exploit the cermet’s strengths: high surface quality and low cutting temperatures. Select the single-sided chipbreaker and grade combination according to the workpiece Stahl grade and the machine’s rigidity to achieve optimal outcomes.

Practical advantages and expected outcomes in production

Using this CCMT insert reduces the need for secondary finishing in many standard turning tasks, as the material-grade pairing minimises common defects and produces uniform surfaces. The combination of ISO standard geometry, robust clamping interface and a finishing-oriented cermet supports efficient batch production where repeatability and surface integrity matter. For specialised materials or unusual alloys, a brief application review with technical advisors is recommended to confirm cutting data and holder choice.

FAQ

What machining tasks suit this insert best? The CCMT09T304 NS9530 insert is optimised for finishing operations on Stahl, especially continuous cuts and small depths of cut where a high-quality surface is required.

Which holders are compatible with the insert? Compatibility depends on holder form, clearance, tolerance class, fixing method, size and thickness; ISO CCMT holders and matching clamping kits are suitable for this insert.

How does the NS9530 grade affect tool life and surface finish? The NS9530 cermet provides a sharp cutting edge and lower cutting forces, which improves surface finish and reduces the tendency for built-up edge in finishing applications.

Is the insert suited for roughing operations? As a finishing-grade cermet, the CCMT09T304 NS9530 is not intended for heavy roughing; it is best applied where precision and surface quality are priorities.

What are the key mounting dimensions to check before use? Verify the plate thickness (3.97 mm), size (09), corner radius (0.4 mm), and the cylindrical hole with countersink to ensure correct seating and secure clamping.
