TPMR 110304 NS9530 Turning indexable insert – Tungaloy

The TPMR 110304 NS9530 is an ISO-format turning indexable insert designed for finishing operations on steel, offering a sharp cutting edge, low cutting forces and high surface finish in continuous cutting and small-depth passes.

Uncoated cermet grade NS9530
Sharp edge for high surface finish
Compatible with ISO turning holders
11° clearance and 0.4 mm corner radius

Achieve superior surface finish with a finishing cermet

This insert is a dedicated finishing solution based on the NS9530 uncoated cermet grade, engineered to deliver a high surface finish when turning steel. The combination of a sharp cutting edge and low cutting forces reduces burr formation and minimises surface irregularities, making it especially suitable for final passes and components where visual and dimensional quality are critical. For shops focused on repeatable part quality, the finishing behaviour reduces rework and polishing steps, leading to measurable productivity gains in batch production or precision component work.

Consistent geometry for predictable tool performance

The geometry of this triangular insert supports reliable and repeatable machining results: a 0.4 mm corner radius, 11° clearance and a 60° lead angle provide stable contact conditions and controlled chip flow. The insert thickness of 3.18 mm and the ISO designation ensure compatibility with standard ISO turning holders; fitment depends on form, clearance angle, tolerance class, fastening method, size and thickness. Clear specification of these parameters aids process planning and reduces the risk of incorrect holder selection, so changeover time and setup variance are kept to a minimum.

System integration that improves throughput

Integration into a full turning system — insert, external holder or boring bar, shim/clamp set and replacement screws — is straightforward thanks to the ISO format. The one-sided chipbreaker and the finishing nature of the grade are optimised for continuous turning, where consistent chip formation and low cutting forces reduce vibration and heat, extending tool life and preserving edge integrity. For production environments that prioritise surface quality and predictable cycle times, this insert supports efficient machining strategies and helps maintain stable, repeatable results across shifts.

FAQ

What materials is this insert suitable for?
The TPMR 110304 NS9530 is a finishing-grade cermet insert intended primarily for steel machining; it delivers low cutting forces and a fine surface finish on typical steel alloys.

Can the insert be used for internal turning as well as external?
Yes — the ISO format and geometry of this insert support both external and internal turning when mounted in a suitable external holder or boring bar that matches the insert form and size.

How does the one-sided chipbreaker affect machining?
The one-sided chipbreaker on this finishing insert promotes controlled chip formation during continuous cuts, helping to maintain a sharp edge and consistent surface quality without promoting heavy chipbreaking that would be required for roughing.

What are the key geometric specifications to check before ordering?
Verify the insert designation (TPMR 110304), corner radius 0.4 mm, thickness 3.18 mm, size 11 mm, clearance 11° and triangular form to ensure compatibility with the chosen holder and clamping system.

Is this uncoated cermet grade better than coated carbide for finishing?
For many finishing tasks on steel, the uncoated NS9530 cermet offers a sharper edge and reduced adhesion tendencies, resulting in superior surface finish at small depths of cut; coated carbides may offer better wear resistance in abrasive or interrupted conditions.
