TPGT 110302 NS9530 — ISO triangular turning insert with W15 chipbreaker and 11° relief by Tungaloy

A TPGT110302L-W15 NS9530 turning insert designed for precise external and internal turning, optimised for fine finishing of Stahl under continuous-cut conditions

• ISO triangular insert, format 110302
• Uncoated cermet NS9530 for fine finishing
• 11° relief with 0.2 mm corner radius
• Cylindrical hole with 40°–60° countersink

Achieve superior surface quality with a sharp cermet edge

The uncoated cermet grade NS9530 delivers a consistently sharp cutting edge that reduces cutting forces and supports high-quality finishes on Stahl. Cermet is a metal-ceramic composite that combines ceramic wear resistance with metallic toughness; this balance retains edge geometry longer than conventional ceramics while offering finer microgeometry than many carbides. For finishing operations and small depths of cut, the result is a measurable improvement in surface finish and reduced need for rework, particularly when used in continuous turning where stability is high.

Guaranteed fit in ISO tool systems and secure clamping

As part of the ISO turning insert family, compatibility with the toolholder depends on form, relief angle, tolerance class, clamping method, size and thickness. The triangular form offers three usable edges per insert, and the central cylindrical hole with a one-sided countersink (40°–60°) ensures reliable clamping and repeatable seating in indexable holders. Specifying the correct holder geometry and tolerance class prevents misalignment and enables fast changeovers while maintaining cutting accuracy across batches.

Recommended materials and cutting strategy for best results

This finishing grade is tailored to Stahl and performs best in steady, continuous cuts with small depth per pass. The 0.2 mm corner radius reduces stress concentration at the tip, promoting uniform contact and a consistent work-hardened layer on the component surface. To exploit the insert’s potential, use moderate cutting speeds and feed rates appropriate for finishing; avoid heavy interrupted cuts that would overload the fine cutting edge. The outcome is smoother component faces and reduced secondary processing.

Practical selection tips: matching holder, relief and chip control

Choose a holder that matches the insert’s 11° relief and size to secure the 3.18 mm thickness and the 11 mm inscribed diameter, ensuring stable cutting geometry. The W15 chipbreaker is tuned for finish turning, providing controlled chip flow without compromising edge sharpness. The insert substrate of Hartmetall contributes to rigidity and predictable wear behaviour, supporting productive turning with repeatable tolerance achievement and surface consistency.

FAQ

What materials is this insert best suited for?
The TPGT110302L-W15 NS9530 insert is optimised for finishing Stahl; its uncoated cermet composition delivers low cutting forces and excellent surface quality in continuous turning operations.

How is compatibility with a toolholder ensured?
Compatibility depends on form, free angle (11°), tolerance class, clamping method, plate size and thickness; the insert’s cylindrical hole and countersink help ensure repeatable clamping in ISO-compliant holders.

What cutting conditions are recommended for the NS9530 grade?
Use moderate finishing speeds with small depths of cut and steady feed to exploit the NS9530 edge retention and the 0.2 mm corner radius; the grade is intended for continuous cuts rather than heavy interrupted cuts.

How does the W15 chipbreaker affect performance?
The W15 chipbreaker is designed for finishing applications, promoting controlled chip flow without compromising the fine cutting edge, which supports consistent surface results and easier chip evacuation.

Is the insert suitable for internal turning as well as external turning?
Yes; the triangular ISO insert geometry and reliable clamping make the TPGT110302L-W15 suitable for both external and internal finishing tasks when matched with the correct holder.
