TCMT16T304 NS9530 TCMT 16T304 NS9530 Turning insert by Tungaloy

The TCMT16T304 NS9530 is an ISO‑standard triangular finishing insert intended for turning; it delivers low cutting forces and excellent surface quality on steels, especially where continuous cuts and small depths of cut are required.

• ISO triangular insert for finishing
• Uncoated cermet grade NS9530
• 0.4 mm corner radius for fine finishes

Efficient finishing for demanding steel turning

The finishing grade NS9530, supplied as an uncoated cermet, is engineered for stable cut conditions and superior surface results when turning steel. Its composition supports a sharp cutting edge with reduced cutting forces, which translates into lower spindle load and predictable chip flow during continuous finishing passes. This makes the insert particularly suitable for applications where part tolerances and surface integrity are decisive, such as shaft finishing or precision external diameters. The result is reliable component quality with fewer rework cycles.

Geometry that reduces force and improves surface quality

The triangular ISO insert geometry combined with a 0.4 mm corner radius and a 7° relief angle creates a cutting geometry that balances edge strength with low intrusion into the workpiece. Lower cutting forces mean less vibration and improved dimensional stability; the geometry therefore supports consistent machining windows and smoother finishes. The insert’s 0.4 mm radius helps achieve a fine surface texture while the overall angle and thickness maintain edge robustness for repeatable performance.

Practical compatibility and mounting guidance for production

As an ISO‑norm insert, compatibility with holders is governed by the insert form, relief angle, tolerance class, fixing method, size and thickness. The TCMT format and 16 mm size work with standard triangular external holders or boring bars; the plate is supplied with a cylindrical hole and single‑side countersink (40°–60°) to suit common clamping systems. With a 3.97 mm thickness the insert offers a reliable seat and torque resistance in the clamp. Choosing a matching single‑side chipbreaker and the NS9530 grade according to workpiece material and cutting parameters will ensure the best combination of surface finish and tool life.

FAQ

What materials is this insert best suited for? The TCMT16T304 NS9530 is a finishing grade designed primarily for machining steel; the uncoated cermet composition supports continuous cuts and high surface quality on steel workpieces.

Can this insert be used for internal turning? Yes, the insert’s triangular form and single‑side chipbreaker make it suitable for both external and internal turning applications when paired with an appropriate boring bar.

How does the 0.4 mm corner radius affect surface finish? A 0.4 mm corner radius helps to produce a finer surface finish while maintaining sufficient edge strength for finishing passes; the geometry reduces chatter and improves dimensional consistency.

Is a special holder required for this ISO insert? No special holder is required, but holder compatibility depends on insert form, relief angle, tolerance class, fixing method, size and thickness; a standard TCMT external holder or a correctly sized boring bar is typically used.

What is the purpose of the cylindrical hole and countersink? The cylindrical hole with single‑side countersink (40°–60°) ensures secure clamping and correct seating in standard insert holders, improving repeatability and torque resistance during turning.
