TNGG 110308 NS520 Tungaloy indexable turning insert

TNGG110308-01 NS520 Tungaloy indexable insert is an ISO-standard triangular insert for precision turning, optimised for finishing to light machining of steel where surface finish and dimensional accuracy are priorities

• Triangular ISO profile for robust clamping
• Cermet grade NS520 for fine surface finish
• 0° relief for stable turning performance

Consistent finishing performance for steel components

The TNGG110308-01 insert is specified for finishing and light cutting of steel and is supplied in the NS520 cermet grade, a coated cermet designed to deliver an excellent balance between wear resistance and surface quality. Its material combination supports a uniform wear pattern, which reduces the need for frequent insert changes and helps maintain dimensional stability across batches. For manufacturers aiming to reduce rework and improve first-pass yield, this grade provides a predictable tool life and reproducible results under stable cutting conditions.

ISO compatibility and secure clamping reduce setup risks

Designed as an ISO turning indexable insert, the triangular form and standardised dimensions make holder selection straightforward: compatibility depends on shape, relief angle, tolerance class, fastening and thickness. The insert features a cylindrical central hole and a defined seating geometry that ensure secure fastening in suitable external holders or boring bars. Using an insert that matches the holder by form and tolerance reduces the risk of improper clamping, vibration and inconsistent cutting, thereby supporting process reliability on the shop floor.

Geometry tuned for surface finish and edge stability

With an included angle of 60° and a corner radius of 0.8 mm, this insert balances edge strength and surface integrity. The relatively small corner radius helps achieve fine surface finishes while still providing sufficient edge support for light interruptions. The 0° relief (free angle) is appropriate for neutral cutting orientations and contributes to controlled cutting forces in finishing passes. Select the chipbreaker variant 01 to match typical steel machining conditions; it promotes predictable chip formation when paired with suitable feeds and speeds.

Economic benefits through reduced downtime and predictable wear

Cermet and coated cermet grades such as NS520 are particularly effective where surface quality and repeatability matter. The material’s resistance to adhesive wear and its ability to maintain an intact cutting edge under finishing parameters reduce machine downtime for insert changes and secondary operations. In practice this results in improved process throughput, less manual rework and a clearer cost-per-part calculation. For batch production and high-mix environments, the predictable performance of this insert supports stable planning and economical machining.

FAQ

What machining tasks is this insert intended for?
The TNGG110308-01 NS520 Tungaloy indexable insert is intended primarily for finishing and light turning of steel, offering improved surface finish and tight dimensional control.

Which materials can be machined with this grade?
The NS520 cermet grade is tailored for steel machining; it provides good surface integrity and uniform wear when used under finishing conditions on steel workpieces.

How does the triangular form affect holder selection?
Holder compatibility is determined by insert form, relief angle, tolerance class, fastening, size and thickness; the triangular ISO profile ensures easy matching with standard external holders or boring bars designed for this geometry.

What are the key geometric values to consider when planning cuts?
Consider the 60° included angle and 0.8 mm corner radius for balancing edge strength and surface finish, and the 0° relief when selecting neutral cutting orientations and feeds.

Is chip control supported for typical steel turning?
Yes, the chipbreaker 01 variant is intended to promote controlled chip formation for finishing to light machining of steel when correct cutting parameters are applied.
