DCMT11T302 NS9530 — ISO turning insert for finishing, Tungaloy

A DCMT11T302 NS9530 indexable insert for turning, designed as a rhombic finishing grade for steel with a sharp cutting edge and suitability for continuous cuts and small depths of cut

• DCMT 11 size, 55° diamond geometry
• NS9530 uncoated cermet finishing grade
• Sharp edge for superior surface finish
• ISO-compatible, cylindrical hole with countersink

Achieve superior surface finish with a low-force finishing grade

The NS9530 uncoated cermet is specifically developed as a finishing grade for steel, combining a very sharp cutting edge with reduced cutting forces to deliver better surface integrity and reduced vibration during light cutting. Because the grade performs best in continuous cuts and small depths of cut, it is ideal for final passes where surface roughness and dimensional accuracy matter. The fine edge geometry helps reduce material smearing and produces consistent finishes on turned components, supporting higher first-pass quality and fewer downstream operations.

Secure clamping and ISO compatibility for reliable setup

Built to ISO geometry, the insert’s DCMT11T302 form and dimensional data ensure compatibility with a wide range of standard turning holders when form, clearance angle, tolerance class, fastening method, size and thickness are matched. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for robust clamping, a 3.97 mm thickness and 55° diamond geometry, while the 7° clearance angle improves cutting clearance during turning. These elements together provide a predictable clamping behaviour and repeatable positioning that contribute to process stability and reduced set-up times.

Effective chip control and application guidance for turning

The single-sided chipbreaker and sharp geometry mean the insert excels at chip formation in finishing cuts where chip size and flow must be controlled to avoid surface damage. Choosing the correct chipbreaker type and grade for the workpiece material and machine rigidity is essential: the presented configuration supports turning of steel under stable cutting conditions and helps lower overall cutting forces. In practice, matching the insert to an appropriate outer holder or boring bar, plus the correct screw and clamping pad, ensures secure fixation and repeatable performance in both external and internal turning tasks.

FAQ

Which materials is the insert suited for? The NS9530 grade is formulated as a finishing grade for steel; the DCMT11T302 NS9530 Tungaloy insert performs best on continuous cuts and small depths of cut with steel workpieces.

What are the key dimensional values for setup? The insert has a size 11 form, 0.2 mm corner radius, 3.97 mm thickness and a 7° clearance angle, which should be matched to the turning holder and clamping hardware.

How is the insert clamped in the holder? Clamping is achieved via the cylindrical hole with a one-sided countersink (40°–60°); the thickness and hole geometry contribute to stable fixation when used with a suitable ISO-compatible holder and the correct screw and pad.

Can this insert be used for roughing operations? The NS9530 uncoated cermet is a finishing grade optimised for low cutting forces and excellent surface quality; it is not intended as a primary choice for heavy roughing where tougher, more wear-resistant grades are typically required.

What benefit does the single-sided chipbreaker provide? The single-sided chipbreaker controls chip formation during finishing cuts, promoting smooth chip flow and reducing the risk of surface damage, which supports consistent part finish and easier chip evacuation.
