Benefit from a precise finishing solution that combines the NS9530 cermet grade with a 0.4 mm nose radius and a 7° clearance angle to deliver low cutting forces and excellent surface quality; order the SCMT09T304 insert directly via Metav Werkzeuge or request guidance from Metav Werkzeuge's consultants if required.

SCMT09T304 NS9530 Tungaloy Turning Insert — 0.4 mm Radius, 7° Clearance

The SCMT09T304 NS9530 is a square ISO indexable insert for turning, optimised as a finishing grade for steel components and suited to continuous cuts and small depths of cut

• Cermet grade NS9530 for fine finishing
• 0.4 mm nose radius for precise contouring
• 7° clearance angle for low cutting forces
• Cylindrical hole with 40°–60° countersink

Superior finish with a low-force cermet grade

The combination of an uncoated cermet in grade NS9530 and a sharp cutting edge is designed specifically for finishing operations on steel, where surface quality matters more than heavy material removal. The microstructure of cermet offers a hard, wear-resistant cutting edge that keeps the cutting forces low, reducing vibration and minimising deflection in less rigid setups. For production environments where consistent surface finish and minimal secondary machining are priorities, this geometry reduces the need for rework and improves downstream process yield.

Robust geometry for repeatable turning accuracy

A square plate with a nominal included angle of 90°, a 0.4 mm nose radius and a 7° clearance angle provides a balance between profile accuracy and edge strength. The insert's 3.97 mm thickness and the cylindrical hole with a single-sided countersink (40°–60°) ensure secure clamping in compatible ISO holders. These geometric choices contribute to repeatable part dimensions and predictable tool life, especially when the correct holder and tolerance class are matched to the insert's form, relief and fastening design.

Practical system benefits and recommended applications

The cutting solution integrates into a standard ISO system: indexable insert, suitable external holder or boring bar, shim/clamping set and replacement screws. The one-sided chipbreaker and finishing cut recommendation support continuous turning and small depths of cut on steel, where the goal is improved surface integrity rather than aggressive material removal. Selecting the correct chipbreaker and matching the NS9530 grade to machine rigidity and cutting data will reduce tool changes and contribute to stable, economical production cycles.

FAQ

What materials is this insert best suited for? The SCMT09T304 in grade NS9530 is optimised for finishing on steel; this cermet grade provides a sharp edge and low cutting forces for high-quality surface finish.

Is the insert compatible with standard ISO holders? Yes, the SCMT09T304 is an ISO-form insert; compatibility depends on matching holder form, relief/freiwinkel, tolerance class, fastening method, size and thickness.

What does the chipbreaker configuration support? The one-sided chipbreaker on this insert is designed for continuous cutting and small depths of cut, helping to control chips and maintain surface integrity during finishing operations.

How does the 0.4 mm radius affect part quality? A 0.4 mm nose radius improves contour accuracy and surface finish while keeping cutting forces moderate, suitable for fine finishing operations where detail and surface appearance are important.

Which SKU should be quoted for ordering? Use SKU 6997721-Tungaloy or Manufacturer SKU TUN6997721 when enquiring or placing an order for this insert.
