SCMT 09T308 NS9530 indexable insert for milling — Tungaloy

The SCMT 09T308 NS9530 is a cermet indexable insert engineered for finishing applications in milling, optimised for continuous cuts and small depths.

• Cermet finishing grade NS9530 for steel
• Sharp cutting edge for high surface quality
• Square insert with 0.8 mm corner radius
• Compatible with Tungaloy milling systems

Optimised finishing performance for steel components

The uncoated cermet grade NS9530 is developed as a finishing material for steels, delivering a sharp cutting edge, low cutting forces and a high surface finish. These characteristics reduce the need for secondary operations by producing consistently fine surfaces during continuous cutting and small-depth passes. The result is improved component quality and fewer rejects in series production, while the reduced cutting forces help to limit tool deflection and maintain dimensional accuracy.

Precision geometry for repeatable results and secure clamping

The insert’s square geometry with a 0.8 mm corner radius and an included angle of 90° provides reliable edge strength and predictable contact conditions at the tool–workpiece interface. The specified 7° relief angle supports stable cutting and reduces rubbing at small depths of cut. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for secure clamping in compatible tool bodies, ensuring repeatable seating and minimised runout across index changes, which contributes to steady component tolerances and process stability.

System compatibility and application versatility for efficient milling

Designed for integration into Tungaloy milling systems, the insert forms part of a modular tool assembly that includes the milling body, clamping screw and, where applicable, a support washer. Typical uses include plan, shoulder, slot, high-feed and contour milling, depending on the selected tool family. The uncoated cermet composition and fine edge hone make this grade particularly suitable where surface integrity and low cutting loads are priorities, offering a balance between productivity and finish quality in finishing operations.

FAQ

What materials is the insert suitable for?
The SCMT 09T308 NS9530 insert is a finishing-grade cermet intended primarily for steel machining, optimised for continuous cuts and small depths to achieve high surface quality.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius balances edge strength and surface finish: it reduces edge chipping risk while helping to maintain a fine finished surface in finishing passes with the Tungaloy insert.

Which milling operations are typical for this insert?
Typical operations include plan, shoulder, slot, high-feed and contour milling when used in the appropriate Tungaloy milling tool family and body.

Is the insert compatible with other tool systems?
The insert is intended for use in Tungaloy milling systems and requires matching seat geometry, clamping screw and, if needed, a support washer for correct assembly.

What does the insert’s hole and countersink provide?
The cylindrical hole with a one-sided countersink (40°–60°) enables secure clamping and precise seating, which helps to reduce runout and maintain repeatable cutting conditions.
