TPMT 16T308 NS9530 ISO turning insert — Tungaloy, uncoated cermet finishing grade

The TPMT 16T308 NS9530 is an ISO triangular turning insert designed for finishing steel, optimised for continuous cuts and fine surface quality in external and internal turning applications.

• ISO triangular insert with central hole
• Uncoated cermet grade NS9530 for finishing
• 0.8 mm corner radius for fine surface finish
• 11° clearance and 60° insert angle

Consistent finishing quality with uncoated cermet technology

The insert offers a sharp cutting edge and low thermal sensitivity thanks to its uncoated cermet composition (grade NS9530), which is engineered for fine finishing on steel. Cermet materials combine ceramic and metallic binders to deliver a stable edge that reduces cutting forces and improves surface finish at small depths of cut. For shops aiming to standardise part quality, this results in fewer rework cycles and more predictable batch-to-batch results. The material choice also supports continuous cutting operations where a steady cut and minimal burr formation are priorities.

Geometry and holder compatibility for efficient changeovers

With a triangular shape, a 0.8 mm corner radius and an ISO code of 16T308, this insert fits common ISO-indexable holders when the form, clearance, tolerance class, fastening and thickness match. The insert includes a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping and repeatable positioning. Explaining ISO codes: the designation indicates shape and size so that toolrooms can quickly identify compatible insert seats and clamping sets, reducing setup time and avoiding costly trial-and-error during tool changes.

Practical advantages in everyday turning and process planning

The chipbreaker version 24 is tuned for controlled chip formation during finishing passes, supporting both external and internal turning where continuous-cut stability is required. Thanks to the geometry and grade, the insert lowers cutting forces, which helps maintain spindle load limits and extends tool life of both the insert and holder.

FAQ

What turning tasks is this insert best suited for? The TPMT 16T308 NS9530 insert from Tungaloy is intended primarily for finishing operations on steel, suitable for both external and internal turning where a high-quality surface is required.

Why choose the NS9530 grade for finishing? NS9530 is an uncoated cermet grade that provides a sharp cutting edge with low cutting forces and excellent surface integrity, making the insert a strong choice for fine finishing with continuous cuts.

How is compatibility with a holder determined? Compatibility depends on ISO designation, form, clearance angle, tolerance class, fastening, size and thickness; the TPMT 16T308 geometry and 3.97 mm thickness must match the selected holder and mounting set.

Is this insert suitable for interrupted or heavy roughing cuts? The TPMT 16T308 NS9530 is optimised for continuous finishing and small depth cuts; heavy interrupted or aggressive roughing is not its primary application.

What practical effect does the 0.8 mm corner radius have? A 0.8 mm corner radius improves surface finish and edge strength for finishing passes while maintaining acceptable cutting forces for stable machining.
