CPMT 09T308 NS9530 ISO Turning Insert, 11° relief – Tungaloy

The CPMT09T308 NS9530 is a rhombic ISO turning insert designed for finishing operations on steel, offering an uncoated cermet grade with an 11° relief for continuous cuts and high surface quality.

• CPMT09T308 ISO rhombic insert, 11° relief
• Uncoated cermet NS9530 for fine finishing
• Single-sided chipbreaker, suitable for continuous cut
• Compatible with ISO holders, 3.97 mm thickness

Consistent finishing performance for steel components

The finishing grade NS9530 is optimised for turning of steel where a sharp cutting edge and low cutting forces are required. As an uncoated cermet, the grade reduces rubbing and produces a superior surface finish at small depths of cut and during continuous cutting cycles. This delivers a reliable dimensional outcome and minimises post-process polishing, supporting tighter tolerances and fewer reworked parts.

Secure clamping and standardised geometry for easy integration

Standard ISO geometry and the rhombic plate outline make holder selection straightforward: the 11° relief angle, 3.97 mm plate thickness and defined plate size ensure repeatable seating and clamping. The insert features a cylindrical hole with a single-sided countersink (40°–60°) which assists accurate alignment and fastening. Clear compatibility criteria—shape, relief angle, tolerance class, fastening, size and thickness—simplify toolroom logistics and reduce setup time.

Predictable chip control and economical process stability

A single-sided chipbreaker tailored for finishing supports consistent chip formation during continuous feeds, improving swarf evacuation and reducing the risk of built-up edge. Together with the NS9530 material properties, this promotes predictable chip control and steady tool wear behaviour, translating into longer effective cutting times and lower overall tooling costs per manufactured component. Selection of the correct chipbreaker and grade according to workpiece material and machining stability remains essential for optimal results.

FAQ

What is the primary application of this insert?
The CPMT09T308 NS9530 turning insert is intended for finishing turning operations on steel, optimised for continuous cuts and small depth-of-cut conditions.

Which holder characteristics must be checked for compatibility?
Compatibility depends on holder shape, relief angle (11°), tolerance class, fastening method, plate size and thickness (3.97 mm), so choose an ISO holder that matches these dimensions.

Is the NS9530 grade coated or uncoated?
NS9530 is an uncoated cermet finishing grade designed to provide a sharp edge and low cutting forces for improved surface finish.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert supports predictable chip formation during continuous feeds, aiding chip control and reducing the chance of built-up edge.

Can this insert be used for internal turning?
Yes, the ISO rhombic shape and standardised dimensions make the insert suitable for both external and internal turning when paired with the appropriate boring bar.
