SCMT09T302 NS9530 ISO turning insert for finishing steels — Tungaloy

SCMT09T302 NS9530 is an ISO-format indexable turning insert designed for finishing operations on steel, offering a sharp edge geometry and an uncoated cermet grade optimised for continuous cuts and fine surface quality.

• Precision finishing grade NS9530
• Sharp cutting edge with low cutting forces
• Square ISO 09 form, 0.2 mm corner radius
• Cylindrical hole with one-sided countersink

Exceptional surface quality for finishing turns

The uncoated cermet grade NS9530 delivers a sharp cutting edge that reduces cutting forces and promotes superior surface finishes when turning steel. Thanks to the fine microstructure of the cermet, the insert minimises built-up edge formation during continuous cuts and short infeed passes, making it an excellent choice for fine turning and light finishing passes. This combination of material and geometry helps maintain consistent dimensional accuracy and surface integrity on turned components.

Secure fit and proven ISO compatibility

Designed as an ISO indexable insert in the square ISO 09 format, the insert features a cylindrical hole with a one-sided countersink (40°–60°) and a nominal thickness of 3.97 mm, ensuring secure clamping in compatible external holders or boring bars. Compatibility is governed by form, clearance angle, tolerance class, attachment type, size and thickness; matching these parameters ensures stable clamping, repeatable seating and reliable repeatability across tool changes. The 7° clearance and 90° approach suit conventional holder geometries for general turning setups.

Optimised geometry and process advantages

With a 0.2 mm corner radius, the cutting edge balances edge strength and surface finish, allowing small depths of cut and continuous cutting regimes without sacrificing productivity. The one-sided chipbreaker supports controlled chip formation for finishing conditions in steel, while the uncoated nature of the insert emphasises sharpness and low cutting resistance rather than coating-enhanced wear resistance—ideal where low cutting forces and top-quality surfaces are the primary objectives. For many finishing tasks, this results in reduced hand-finishing and shorter process chains.

FAQ

What materials is this insert suitable for?
The SCMT09T302 NS9530 insert is optimised for steel finishing; the NS9530 cermet is selected for low cutting forces and excellent surface quality in continuous turning operations.

Which holder types fit this ISO insert?
Compatibility requires a square ISO 09 pocket with matching thickness and attachment; holders and boring bars that accept ISO 09 square inserts with a 3.97 mm thickness and a 90° approach are suitable.

How does the 0.2 mm corner radius affect machining?
A 0.2 mm corner radius offers a balance between edge strength and surface finish, enabling fine finishing passes with reduced risk of edge chipping during light cuts.

Is the insert coated?
The SCMT09T302 NS9530 is an uncoated cermet insert, prioritising a sharp edge and low cutting resistance for finishing rather than coating-enhanced wear resistance.

What is the purpose of the cylindrical hole and countersink?
The cylindrical hole with one-sided countersink (40°–60°) ensures secure clamping and defined seating in compatible indexable insert holders, supporting repeatable tool changes and stable cutting conditions.
