CPMT09T302 NS9530 — ISO rhombic turning insert, 80° by Tungaloy

A CPMT09T302 NS9530 insert for turning, optimised for fine finishing of steel and continuous cuts with low cutting forces.

• ISO rhombic insert for turning, 80° angle
• Uncoated cermet grade NS9530 for fine finishing
• Single-sided chipbreaker for continuous cuts
• Cylindrical hole with one-side countersink

High-quality finishing with an uncoated cermet grade

The insert is made from an uncoated cermet intended as a finishing grade for steel, which results in a sharp cutting edge and reduced cutting forces. This leads to improved surface integrity on turned parts and less tendency for built-up edge during continuous cutting conditions. The material choice and edge geometry make the component particularly suitable where small depths of cut and a high-quality surface are required; predictable wear behaviour supports consistent batch-to-batch quality. The combination of a fine cutting edge and the NS9530 grade ensures efficient finishing without the need for coated alternatives in many standard steel applications.

Precise geometry and holder compatibility for repeatable results

Designed as an ISO rhombic insert with an included angle of 80° and a clearance (relief) angle of 11°, the plate provides stable contact and controlled chip flow when mounted in compatible holders. The 0.2 mm corner radius balances edge strength and surface finish, while the plate thickness of 3.97 mm contributes to rigidity in the tool assembly. The insert features a cylindrical hole with a one-side countersink (40°–60°) for secure clamping; compatibility with a toolholder is determined by form, relief, tolerance class, fastening method, size and thickness. These characteristics result in dependable seating and repeatable positioning, which are essential for maintaining tolerances in serial production.

Practical application guidance and performance advantages

This turning insert performs best in external and internal finishing operations on steel where continuous cutting and smaller cut depths are typical. The single-sided chipbreaker is matched to the grade and intended cutting conditions to promote stable chip formation and easy evacuation. For machining strategy, select a chipbreaker and holder that suit the workpiece stability and cutter overhang; the combination of low cutting forces and sharp edge reduces vibration sensitivity and often improves tool life in stable setups. The insert is supplied as part of a system that includes a compatible holder, backing pad or clamping set and replacement screws, where correct matching yields the most reliable process performance and surface results.

FAQ

What materials is this insert intended for?
The CPMT09T302 NS9530 is a finishing grade developed for machining steel; its uncoated cermet composition achieves low cutting forces and an excellent surface finish on typical steel applications.

Which geometry and angles does the insert use?
This ISO rhombic insert has an included angle of 80° and a relief angle of 11°, with a 0.2 mm corner radius and a plate thickness of 3.97 mm for stable mounting and consistent cutting behaviour.

How does the NS9530 grade perform compared with coated grades?
The NS9530 uncoated cermet offers a very sharp edge and reduced cutting forces that are advantageous for finishing and continuous cuts; coated grades may be preferable for higher-temperature or interrupted cutting conditions.

What chip control does the plate provide?
The insert features a single-sided chipbreaker designed to produce stable chip formation in finishing operations, helping to maintain surface quality and reduce the risk of chip-related issues.

How is the insert identified for ordering?
Order using the designation CPMT09T302 NS9530 (Tungaloy) or the article number 6951182; the manufacturer SKU is TUN6951182 for unambiguous identification.
