TPGT 080204 NS9530 Tungaloy Turning Insert — ISO triangular finishing insert for steel

A TPGT080204L-W08 NS9530 indexable turning insert engineered for finishing operations on steel, offering a sharp edge and a chipbreaker tuned for continuous cuts and small depths of cut.

• Uncoated cermet grade NS9530
• Sharp edge for superior surface finish
• Triangular ISO shape, 60° included angle
• Central hole with countersink for secure clamping

Superior surface quality for finishing passes

The combination of uncoated cermet construction and the NS9530 grade produces a notably sharp cutting edge, which lowers cutting forces and promotes a high-quality surface finish on steel. The small corner radius (0.4 mm) concentrates the cut for narrow, precise passes, making the insert particularly effective for continuous turning with small depths of cut. For operations where fine surface integrity and minimal post-processing are priorities, this geometry and grade reduce the need for secondary finishing while maintaining steady performance.

Secure fit and repeatable clamping for productivity

Designed to the ISO indexable plate standards, the insert’s triangular form with a 60° included angle and a central hole with a cylindrical bore plus one-sided countersink (40°–60°) provides dependable seating in compatible external holders or boring bars. The 11° relief angle and 2.38 mm plate thickness ensure consistent engagement and support under cutting loads, while the standard size designation (08) aids in holder selection. These dimensional features translate into reliable repeatability and easier tool-change procedures on production equipment.

Practical system integration and application advice

This insert is intended as part of a complete turning system: ISO indexable plate, matching external holder or boring bar, underlay/clamping set and replacement screws for secure assembly. The W08 chipbreaker is optimised for finishing cuts, supporting stable chip control during steady, continuous machining of steel. As an uncoated cermet, the grade performs best where sharp edges and low cutting forces are required rather than high-temperature resistance; it is therefore recommended for finishing steel components with fine tolerances rather than heavy interrupted cuts.

FAQ

What materials is this insert optimised for?
The TPGT080204L-W08 NS9530 insert is optimised for finishing operations on steel; the uncoated NS9530 cermet grade favours low cutting forces and high surface quality.

Can this insert be used for interrupted cuts?
This finishing grade and its chipbreaker W08 are intended for continuous cuts and small depths of cut; for heavy or interrupted machining a more robust grade or geometry is recommended.

How is compatibility with holders determined?
Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness; the ISO triangular form and the central hole/countersink allow secure mounting in matching external holders or boring bars.

Is the insert coated?
No, the NS9530 designation indicates an uncoated cermet plate, selected for its sharp edge and fine finishing capability rather than thermal resistance from coatings.

What is the purpose of the W08 chipbreaker?
The W08 chipbreaker is tuned for finishing: it promotes stable chip flow during steady, small-depth passes and helps maintain surface integrity on steel.
