TCMT 090204 NS9530 – ISO triangular turning insert for finishing steel by Tungaloy

The TCMT090204 NS9530 is an ISO-format triangular turning insert optimised for finishing steel, offering a sharp cutting edge and low cutting forces for continuous-cut applications.

• Sharp cutting edge for superior surface finish
• Uncoated cermet grade NS9530 for low cutting forces
• ISO TCMT090204 triangular format for wide compatibility
• 7° clearance with single-sided chipbreaker

Precision finishing performance for turning operations

The TCMT090204 insert is engineered as a finishing solution for turning where surface quality and predictability matter. The uncoated cermet grade NS9530 provides a consistently sharp cutting edge, which reduces friction and contributes to low cutting forces during continuous cuts. For workshops seeking repeatable results on steel, the combination of a sharp geometry and a finish-oriented grade reduces workpiece rework and improves downstream processes by delivering stable dimensional accuracy and fine surface texture.

Secure mounting and ISO-based compatibility for reliable setups

Compatibility with toolholders is governed by the insert form, clearance angle, tolerance class, fastening method, size and thickness. The triangular ISO TCMT090204 format ensures broad compatibility with standard external holders and boring bars, while the cylindrical hole + single-sided countersink (40°–60°) secures consistent clamping and repeatable positioning. This predictable fixation minimises micro-movements under load, keeping tool life and part tolerances stable during series production.

Geometry and chip control designed for surface integrity

A moderate 0.4 mm nose radius and the single-sided chipbreaker geometry have been selected to favour surface integrity over heavy material removal, making the insert ideal for small depths of cut and continuous finishing passes. The 7° clearance angle reduces rubbing on the flank face and helps maintain the sharp cutting edge, while the 2.38 mm thickness contributes to stiffness and resistance to edge chipping. These design choices translate into fewer scrap parts and a smoother machining process when finishing steel components.

Practical application advice and efficiency gains

For routine finishing of steel components, the insert excels in delivering consistent results on stable setups and during uninterrupted cuts. The single-sided chipbreaker assists in forming controllable chips at finishing cutting parameters, reducing the risk of surface damage. Where process reliability is a priority, the insert’s finish-oriented grade and ISO conformity support high throughput with consistent quality. For identification and ordering, refer to the article number and manufacturer SKU when specifying the insert for procurement or replacement in toolkits.

FAQ

Which materials is this insert suited for? The TCMT090204 NS9530 insert is optimised for finishing steel; the NS9530 uncoated cermet grade favours low cutting forces and fine surface finishes when turning steel components.

What is the clearance angle and why does it matter? A 7° clearance angle reduces flank contact and rubbing, helping the sharp cutting edge to maintain quality over repeated passes and improving surface integrity during finish turning.

How is the insert secured in a holder? The insert uses a cylindrical hole with a single-sided countersink (40°–60°) for positive clamping; compatibility depends on the holder’s form, tolerance class, fastening method, size and thickness.

What chip control can be expected? The single-sided chipbreaker is designed to produce manageable chips at finishing parameters, supporting continuous-cut operations and reducing the risk of surface damage.

How can the insert be identified for ordering or replacement? Refer to article number 6997724 or manufacturer SKU TUN6997724, and specify the TCMT090204 NS9530 designation when ordering to ensure the correct finishing insert is supplied.
