TPMT 130308 NS9530 turning insert — Tungaloy, triangular TPMT130308-PS

TPMT130308-PS NS9530 is a triangular indexable insert engineered for finishing operations in turning, optimised for continuous cuts and high surface quality

• Uncoated cermet grade NS9530
• Fine 0.8 mm corner radius
• PS chipbreaker for finishing
• ISO TPMT130308 form, 11° clearance

Consistent finishing quality with lower cutting forces

The uncoated cermet NS9530 grade is designed as a finishing solution for steel, combining a sharp cutting edge with low cutting forces to reduce workpiece deformation and improve dimensional stability. For light depths of cut and continuous cutting conditions, this insert reduces the need for secondary finishing, helping to shorten cycle times and lower overall machining costs. The sharp edge and brittle-adhesive wear behaviour of the grade produce a high surface finish, making it suitable for components where visual appearance and tight tolerances matter.

Secure clamping and ISO compatibility for repeatable results

The triangular TPMT130308 geometry, with an 11° clearance and a cylindrical hole with single-sided countersink (40°–60°), provides reliable mechanical clamping in compatible holders. The standardised form ensures straightforward matching to ISO-compatible toolholders; correct selection of holder, shim and clamp is essential to exploit the insert’s potential. The 3.18 mm plate thickness and 13 mm size give a stable platform for finishing cuts, while the 0.8 mm corner radius supports fine edge strength without compromising surface quality.

Application guidance to maximise tool life and part quality

For external and internal turning in continuous cut scenarios, the PS chipbreaker is optimised to control chip flow during finishing passes and to maintain a steady cutting zone. The insert performs best with small feedrates and modest depths of cut; stability of the setup and correct selection of the clamping system are decisive factors for repeatable tool life. Matching the insert to an appropriate holder and maintaining stable cutting conditions reduce tool wear and help achieve consistent tolerance adherence, resulting in higher first-pass yields and lower rework rates.

FAQ

Which materials is this insert intended for? The TPMT130308-PS NS9530 insert is formulated as a finishing grade for steel; the uncoated NS9530 cermet provides low cutting forces and a high-quality surface finish in continuous cutting conditions.

Is the TPMT130308-PS coated or uncoated? This turning insert is an uncoated cermet (NS9530), chosen for its sharp cutting edge and suitability for finishing applications.

How does the PS chipbreaker influence machining? The PS chipbreaker on this insert controls chip formation during finishing passes, supporting steady chip flow and improved surface quality when machining with small depths of cut.

What clamping and holder features must be observed? Compatibility depends on the ISO TPMT130308 form, the 11° clearance, the 3.18 mm thickness and the hole/countersink configuration; match the insert to an ISO-compatible holder and correct clamping components for repeatable performance.
