TPMT 16T304 NS9530 turning insert by Tungaloy — uncoated cermet finishing grade, 60° triangle

A TPMT16T304-23 NS9530 insert engineered for precision turning of steel, optimised for continuous cuts and small depths of cut with a low cutting-force geometry.

• Cermet finishing grade NS9530 for steel
• Sharp cutting edge for superior surface finish
• ISO 16T304 triangular insert, 60° included angle
• 0.4 mm corner radius with cylindrical hole and countersink

High-quality finishing with reduced cutting forces

The uncoated cermet grade NS9530 is formulated for finish turning of steel where low cutting forces and a razor-sharp edge are decisive. A sharp edge reduces burr formation and vibration, which leads to a high surface finish and minimised rework. In continuous cutting conditions and with small depths of cut the combination of grade and geometry delivers steady performance and consistent component quality, so cycle times remain predictable and scrap rates fall.

Designed for seamless ISO-system integration

The insert follows the ISO designation 16T304, which simplifies tool selection and ensures mechanical compatibility with standard triangular holders. The insert’s 60° included angle and 11° clearance angle are decisive for seating and approach direction; tolerance class, fixation and plate thickness determine final fit. The cylindrical hole with a one-sided countersink (40°–60°) secures repeatable clamping and alignment, reducing set-up time and promoting process stability across batches.

Predictable edge behaviour and chip control

The geometry is supplied with chipbreaker 23, chosen to match the finishing role of the grade; it supports stable chip evacuation during continuous turning. The sharp cutting edge inherent to this grade lowers thrust forces, which benefits both tool life and machine load. Where tool wear monitoring is applied, the insert provides consistent flank wear progression, enabling reliable reconditioning strategies and more accurate tool-change scheduling.

Practical application advice for shop-floor success

Intended primarily for external and internal turning of steel in finishing operations, the insert performs best with modest depths of cut and steady feed to exploit the cermet’s edge integrity. Compatibility with a holder depends on form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters is recommended to avoid mounting errors. For one-off trials or serial production runs, selecting the appropriate chipbreaker and verifying clamping torque will reduce the risk of chatter and ensure optimal surface quality.

FAQ

What materials is this insert designed for? The NS9530 uncoated cermet grade is designed primarily for machining steel; the TPMT16T304-23 NS9530 insert is optimised for finishing cuts on steel workpieces.

How does the 0.4 mm corner radius affect finish and strength? A 0.4 mm corner radius balances a fine surface finish with adequate edge strength; it helps maintain a sharp cutting line while reducing the risk of premature chipping under finishing conditions.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, clearance angle, tolerance class, fastening and plate thickness; the ISO 16T304 designation assists in selecting the correct triangular holder for the TPMT16T304-23 insert.

Is chip control handled by the insert geometry? Yes, the chipbreaker 23 is matched to the finishing application to promote stable chip evacuation during continuous turning and to support a clean surface finish.

Can this insert be used for interrupted cuts? The grade and geometry are optimised for continuous turning and small depths of cut; for heavily interrupted cuts, consider a different grade or a more robust geometry.
