SCMT 09T302 NS9530 ISO turning insert (finishing) — Tungaloy

SCMT09T302 NS9530 is an ISO-format indexable turning insert designed for finishing operations on steel, offering an uncoated cermet grade for low cutting forces and high surface quality.

• ISO insert SCMT09T302 for precision finishing
• Uncoated cermet NS9530 for superior surface finish
• 7° clearance angle, 0.2 mm corner radius
• Cylindrical hole with one-sided countersink

Outstanding surface finish from a finishing-grade cermet

This indexable insert is built around the NS9530 cermet grade to deliver a consistently fine surface on steels during continuous cuts and small depth passes. The geometry produces reduced cutting forces and a sharp cutting edge that limits material pull-out, so the resulting finish is improved without aggressive cutting parameters. The insert’s 0.2 mm corner radius supports delicate profiling and fine finishes while maintaining dimensional control.

Reliable fit and proven ISO compatibility for production use

Shaped to the ISO profile SCMT with the designation 09T302, the insert is compatible with holders that match in form, clearance angle, tolerance class, attachment, size and thickness. The presence of a cylindrical hole with one-sided countersink (40°–60°) ensures secure clamping and repeatable seating. The plate thickness of 3.97 mm and square format maintain stability during external and internal turning, allowing for predictable chip formation and consistent results in series production.

Durable substrate and controlled chipbreaking for efficient turning

The cutting geometry features a single-sided chipbreaker, optimised for finishing cuts in steel and matched to the uncoated cermet grade to avoid build-up and thermal softening. The insert is produced on a carbide substrate, combining rigidity with edge strength to support long-standing performance in continuous operations. For machining strategies, select feed and depth values aligned with finishing tasks to exploit the grade’s low cutting-force behaviour and achieve the targeted surface quality.

FAQ

Which materials is this insert suited for?
The SCMT09T302 NS9530 Tungaloy insert is specified as a finishing grade for steel and is optimised for continuous cuts and small depths to achieve high surface quality.

How does the 0.2 mm corner radius affect the machining result?
A 0.2 mm radius provides a fine edge geometry that improves surface finish and supports accurate profile details while limiting deflection during finishing operations with the Tungaloy insert.

Is the insert compatible with standard holders?
Compatibility is determined by matching the ISO form, clearance angle, tolerance class, attachment method, size and thickness; the SCMT09T302 follows ISO standards to ensure broad holder compatibility.

What is the purpose of the cylindrical hole with countersink?
The cylindrical hole with one-sided countersink ensures secure and repeatable clamping, improving seating stability and facilitating reliable indexation during production.

Can this insert be used for roughing operations?
This cermet grade NS9530 and the insert geometry are optimised for finishing; for heavy roughing cuts, a grade and chipbreaker designed for higher depths of cut and interrupted cuts should be chosen.
