TPMT 110304 NS9530 — ISO triangular finishing insert for turning by Tungaloy

A TPMT 110304 NS9530 is an ISO‑standard triangular turning insert designed for finishing passes on steel, offering a sharp cermet cutting edge and a small corner radius for superior surface quality.

• ISO triangular TPMT geometry
• Uncoated cermet NS9530 finishing grade
• 0.4 mm corner radius for fine finish
• Cylindrical hole with countersink for secure clamping

Precise finishing where it matters

The TPMT110304-PSF NS9530 combines a sharp cermet cutting edge with a small 0.4 mm corner radius to reduce cutting forces and consistently deliver a fine surface texture on steel components. As a finishing grade, the insert is optimised for continuous cuts and small depth‑of‑cut operations; this reduces vibration and helps maintain dimensional accuracy while producing the desired surface appearance. The material choice and geometry are specifically tuned to lower burr formation and to assist in achieving tighter tolerances during final passes.

Compatibility and system requirements for smooth integration

Compatibility with toolholders is governed by standard ISO characteristics: insert form, relief angle, tolerance class, fastening method, size and thickness. The insert fits into an ISO turning system comprising an outer holder or boring bar, a support shim or clamp set, and replacement screws. The 11° relief angle and triangular shape ensure predictable seating and repeatable positioning, while the cylindrical hole with a single‑sided countersink (40°–60°) improves clamp stability and repeatability during index changes.

Selection guidance and application advantages

Choose the PSF chipbreaker and the NS9530 grade when the priority is a low cutting force and high surface finish on steel. The uncoated cermet construction delivers a sharp edge that reduces built‑up edge tendency in continuous finishing cuts, making it particularly suitable where optical surface quality and minimal post‑processing are required. Operators benefit from extended uninterrupted cycle times and fewer rework operations when the grade and chipformer are matched to the workpiece material and machine stability.

Practical notes on geometry and secure clamping

The triangular form with an included angle of 60° and a thickness of 3.18 mm offers a stable seat in standard ISO TPMT pockets, while the nominal size of 11 mm balances edge life and accessibility in confined geometries. The cylindrical hole plus single‑sided countersink provides a positive mechanical register and reduces the likelihood of insert movement under cutting loads. These design choices combine to support predictable tool behaviour and simple indexation during multi‑edge use.

FAQ

Is this insert compatible with standard ISO TPMT holders? Yes. The insert follows ISO TPMT geometry and will be compatible with holders that accept the 110304 form, taking into account form, relief, tolerance, fastening and thickness.

For which materials is the NS9530 grade recommended? The NS9530 uncoated cermet is specified for finishing operations on steel and is optimised for continuous cuts and small depths of cut to achieve superior surface quality.

Can the insert be used for internal and external turning? The insert is suitable for both external and internal turning applications when mounted in the correct outer holder or boring bar and when the machining strategy matches the insert’s finishing design.

What benefit does the 0.4 mm corner radius provide? A 0.4 mm corner radius balances edge strength with the ability to produce a fine surface finish, reducing vibration and improving dimensional control during finishing passes.

What is the purpose of the PSF chipbreaker and the countersunk hole? The PSF chipbreaker is designed for finishing chip control under stable cutting conditions, while the cylindrical hole with a single‑sided countersink ensures secure clamping and repeatable positioning in ISO toolholders.
