TPGM 070104 NS9530 indexable insert for turning, cermet finishing grade — Tungaloy

The TPGM 070104 NS9530 is an ISO-format indexable insert designed for precision external and internal turning, optimised for finishing operations on steel.

• ISO triangular insert for precision turning
• NS9530 uncoated cermet finishing grade
• 0.4 mm corner radius for fine surface finish
• 11° clearance and 60° form angle for stability

Consistent finishing performance for steel parts

The NS9530 grade is an uncoated cermet specifically formulated as a finishing sort for steel, delivering a sharp cutting edge and low cutting forces. These properties translate into a noticeably high surface finish even at modest feed rates, making the insert particularly suitable for continuous cutting and light cross-sections. By reducing the force transmitted to the component, the insert helps to preserve dimensional accuracy and minimise rework in serial production.

Precision geometry that improves process stability

The insert’s geometry—a triangular form with a 0.4 mm corner radius, 11° clearance and a 60° form angle—is engineered to balance strength and cutting finesse. The small corner radius aids in achieving fine surface texture while the clearance angle reduces rubbing, so tool life can be extended without compromising finish. These geometric features make the component a practical choice where repeatable accuracy and predictable tool behaviour are required in turning cells and CNC lathes.

ISO compatibility simplifies tool system planning

Designed as an ISO-standard indexable plate, the insert integrates into standard external holders and boring bars when matched by form, clearance, tolerance class, mounting and thickness. The system typically comprises the insert, a compatible holder, a support shim or clamp set, and replacement screws—allowing quick changeover and consistent clamping. For customers assessing retrofit or new-tool setups, this ISO conformity reduces specification effort and supports streamlined inventory management.

Practical application notes and chip control

The plate features a one-sided chipbreaker and a cylindrical hole for secure mounting, with a nominal thickness of 1.59 mm. The chipbreaker is optimised for steady chip formation during finishing passes; in combination with the grade chemistry this yields controlled, short chips under continuous-cut conditions. For less experienced planners: a chipbreaker shapes the flow of material away from the cutting edge, improving surface quality and reducing the risk of re-cutting chips on the workpiece.

FAQ

What steels is this grade optimised for?
The NS9530 finishing grade is optimised for a broad range of steels, offering low cutting forces and a sharp edge for superior surface finish when using the TPGM070104 insert.

How should the insert be clamped in the tool system?
Clamping must match the ISO form, clearance and tolerance class; use a compatible external holder with the appropriate shim or clamp set and the specified replacement screws for secure fixation of the insert.

What advantages does the 0.4 mm corner radius provide?
A 0.4 mm corner radius helps produce fine surface textures and reduces the risk of edge chipping in finishing cuts, making it advantageous for light depth-of-cut finishing passes.

Is the plate coated and what does cermet mean?
The insert is an uncoated cermet; cermet combines ceramic and metallic phases to provide a hard, wear-resistant cutting edge with good thermal stability, particularly useful in finishing operations.
