CPMT09T304 NS9530 ISO indexable insert for turning — Tungaloy

The CPMT09T304 NS9530 is an ISO-standard rhombic indexable insert for turning, optimised as a finishing grade for steel with a sharp cutting edge, low cutting forces and reliable surface finish.

• Uncoated NS9530 cermet finishing grade
• Rhombic 09 size with 80° included angle
• 0.4 mm corner radius for edge security
• Cylindrical hole with single-side countersink (40°–60°)

Superior finishing for steel components

The insert is designed as a finishing grade: the uncoated NS9530 cermet provides a fine, consistent cutting edge that reduces built-up edge and delivers improved surface integrity on steel. The combination of a sharp edge and low cutting forces means more stable cutting at small depths of cut, leading to fewer rework cycles and better part-to-part consistency. For shops focused on tight tolerances, this geometry supports precise dimensional control and a high-quality surface without complex parameter tuning.

Geometry and mounting that simplify process integration

The rhombic plate form and 80° included angle support common turning profiles and allow flexible use in both external and internal turning setups. The 11° clearance angle reduces rubbing while maintaining support behind the cutting edge, and the 0.4 mm corner radius balances edge strength with the need for tight finish radii. The insert uses a cylindrical hole with a single-side countersink (40°–60°) for secure clamping; compatibility with the holder depends on form, clearance, tolerance class, fastening and thickness, so matching the insert to a suitable outer holder or boring bar is essential for stable machining.

Practical benefits and recommended applications

This grade is optimised for continuous cutting and small feed/small depth-of-cut finishing operations on steel. The uncoated cermet material improves wear resistance and maintains a sharp cutting geometry for long periods in steady-state cutting, which is particularly beneficial for long-run finishing passes. Select the single-sided chipbreaker when machining stable set-ups where chip control for finishing is required. The insert forms part of a system: the ISO insert, a matching external holder or boring bar, pad/clamp set and replacement screws together determine machining reliability.

System considerations and process guidance

Integration into existing tool systems requires checking form, free angle, tolerance class, fastening, size and thickness to ensure the holder accepts the ISO-standard plate. For best results, pair the insert with a rigid clamping arrangement and machining parameters suited to finishing: modest cutting speeds, steady feed and reduced depth of cut. The straightforward geometry keeps setup time low and simplifies tooling inventory, while the cermet composition supports consistent surface finish across extended runs. Where application advice is needed, consult tooling specialists to align holder choice and cutting data with component requirements.

FAQ

What materials is this insert best suited for?
The CPMT09T304 NS9530 insert is formulated as a finishing grade for steel; the uncoated NS9530 cermet excels in producing fine surface finishes in continuous turning of steel.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius increases edge strength compared with a micro-radius while still supporting fine surface finish; the CPMT geometry balances robustness and finish quality for lower-depth finishing passes.

Is this insert compatible with my holder?
Compatibility depends on holder form, free angle, tolerance class, fastening, size and thickness; the ISO-standard plate is compatible when the outer holder or boring bar matches the CPMT09T304 geometry and clamping method.

What chip control does the insert provide?
The insert features a single-sided chipbreaker designed for finishing conditions and stable setups, providing controlled chip flow during continuous cuts.

Can the CPMT09T304 NS9530 be used for interrupted cuts?
The grade is optimised for continuous cutting and small depths of cut; interrupted cuts may reduce tool life or surface quality, so application-specific testing is recommended.
