SCMT 09T304 NS9530 Tungaloy – Turning insert for finishing on Stahl

SCMT09T304 NS9530 indexable turning insert designed for fine finishing and continuous cuts in Stahl; square format with 90° cutting geometry for reliable external and internal turning.

• Finishing-grade uncoated cermet NS9530
• Square ISO insert SCMT 09, 90° cutting angle
• Low cutting forces and excellent surface finish
• Compatible with holders requiring 09T304 form

Consistent finishing performance with a cermet cutting edge

The SCMT09T304 NS9530 is specified as a finishing-grade, uncoated cermet insert developed to produce very fine surfaces on Stahl during continuous cutting. The combination of a sharp cutting edge and a small 0.4 mm nose radius reduces ploughing and minimises vibrations, which leads to improved first-pass surface quality and fewer rework operations. For operations where chip formation is steady, this grade offers low cutting forces and stable performance, so cycle times can be optimised while maintaining machined tolerances.

ISO conformity and secure clamping for predictable setup

The insert follows ISO geometry for turning inserts, marked as SCMT 09T304, and is manufactured to match holder form, clearance angles and tolerance classes. The square plate format with a nominal 90° approach angle provides versatile orientation options for external and internal turning. The insert is supplied with a cylindrical hole and one-sided countersink (40°–60°) to suit common clamping systems; compatibility is determined by form, clearance angle and thickness. Using holders specified for the 09T304 form ensures repeatable seating and reduces setup variability.

Operational benefits: efficiency, surface quality and tool life

As an uncoated cermet, this grade offers a very sharp, wear-resistant cutting edge that is especially effective for low-depth finishing passes. The material choice supports excellent surface finish without additional dressing, and the low cutting forces contribute to reduced spindle load and longer tool life on matched operations. From a rational perspective, fewer finishing passes and predictable tool change intervals translate into improved productivity and lower unit costs over a production run.

Practical guidance for optimal results in turning

Select a chipbreaker and insert grade that suit the workpiece stability and the chosen feed-and-depth strategy; the single-sided chipbreaker fitted to this plate is intended for controlled chip flow during finishing. Use a stable toolholder and minimise overhang to exploit the small nose radius for excellent surface integrity. For best results on Stahl, maintain continuous cuts and avoid interrupted cutting unless specifically required by the machining strategy. If doubts remain about holder compatibility or process parameters, technical advice is available to align the insert selection with machining requirements.

FAQ

What machining tasks suit this insert best?
The SCMT09T304 NS9530 is intended for finishing turns on Stahl where a fine surface finish and low cutting forces are required, particularly in continuous cutting conditions.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO geometry SCMT 09T304; compatibility depends on holder form, clearance angle and thickness — a holder matching the 09T304 form will ensure correct seating.

Which materials does the NS9530 grade perform well on?
The NS9530 uncoated cermet is optimised for finishing Stahl, offering a sharp edge and stable chip formation for high-quality surface results.

How does the 0.4 mm nose radius affect the finish?
A 0.4 mm nose radius reduces cutting edge contact area and vibration tendency, resulting in smoother surfaces and tighter tolerance control during finishing passes.

Can the insert be used for interrupted cuts?
This grade is optimised for continuous cuts and small depths of cut; interrupted cutting may reduce edge life unless process parameters and machine rigidity are adjusted accordingly.
