TPMT130308-PF NS9530 – triangular ISO turning insert for finishing, cermet grade by Tungaloy

TPMT130308-PF NS9530 is a finishing insert designed for turning operations, offering a sharp cutting edge and optimised chip control for continuous cuts in steel

• Triangular 60° geometry for versatile turning
• Sharp cutting edge for superior surface finish
• PF chipbreaker for controlled chip flow
• 0.8 mm corner radius for fine finishing

Exceptional finish quality from an uncoated cermet grade

The insert uses an uncoated cermet grade engineered to deliver a consistently high surface finish on steel during finishing passes. The combination of a sharp cutting edge and the low-friction behaviour of cermet reduces built-up edge and helps maintain dimensional accuracy across runs. For operations where small depths of cut and continuous feeds are common, this composition supports reduced rework and improved first-pass quality.

Geometry and mounting that give predictable cutting behaviour

Featuring a 60° triangular cutting geometry with a 0.8 mm corner radius and 11° clearance, the insert provides a reliable contact profile and stable engagement with the workpiece. The plate thickness of 3.18 mm contributes to stiffness, while the insert’s specification includes a hole with a cylindrical bore and a single-sided countersink (40°–60°), ensuring secure clamping and repeatable positioning in ISO-compatible holders. These mechanical details translate directly into stable cutting forces and consistent surface results.

Purpose-built for finishing in steel with controlled chip formation

This grade, NS9530, is a finishing specification tailored to turning steel, offering low cutting forces and a sharp edge for fine surface integrity. The PF chipbreaker is optimised for continuous cuts and small feeds, delivering reliable chip control that prevents tangling and minimises downtime for chip clearing. When combined with a properly selected holder and clamping set, the system supports predictable tool life and steady productivity.

Practical benefits for workshop productivity and handling

Adopting this ISO-format insert simplifies tooling logistics: standardised dimensions and hole style make it easy to match to existing holders, while the cermet grade reduces the tendency for work hardening and built-up edge in finishing tasks. The result is predictable tool life, improved throughput and a more cost-effective finishing process. For setups requiring tight tolerances and consistent surface quality, this insert contributes directly to lower rework rates and higher process reliability.

FAQ

What applications is this insert best suited for?
The NS9530 cermet grade is intended primarily for finishing turning in steel; the TPMT130308-PF excels at continuous cuts and small depths of cut where surface quality is critical.

How does the PF chipbreaker influence performance?
The PF chipbreaker on this insert promotes consistent chip control during finishing feeds, reducing the risk of chip entanglement and helping to maintain a clean cutting zone for reliable surface finish.

Which holder features are required for correct mounting?
Secure clamping with a matching ISO-compatible triangular pocket and the correct screw/underlay set is required; the insert’s cylindrical hole and single-sided countersink ensure repeatable seating and alignment in standard holders.

Can this insert handle interrupted cuts?
The NS9530 finishing grade is optimised for continuous cuts; for heavily interrupted machining, a different grade or geometry may be preferable to protect the cutting edge and preserve tool life.

What cutting geometry details affect finish and stability?
The combination of the 60° included angle, 0.8 mm corner radius and 11° clearance delivers a stable contact edge and fine finishing capability with predictable cutting forces for high-quality surfaces.
