TPGT110204 NS9530 Tungaloy turning insert — finishing grade, uncoated cermet, 11° relief

The TPGT110204 NS9530 Tungaloy insert is an ISO‑standard triangle‑form turning insert designed for finishing operations on steel, offering a sharp cutting edge and low cutting forces for continuous cuts and small depths of cut.

• Precision finishing for steel with sharp cutting edge
• Uncoated cermet for superior surface finish
• Triangle form with 60° included angle
• 11° relief angle for low cutting forces

Superior surface quality from a finishing grade

The uncoated cermet grade NS9530 is developed as a finishing grade for steel, delivering a sharp cutting edge and excellent wear resistance that together produce a consistently fine surface finish. In practice, this means fewer follow‑up operations and less time spent on manual finishing. Cermet combines a ceramic phase with metallic binder to give a stable cutting edge at light cutting depths; for continuous turning and small feeds it outperforms many conventional grades when surface integrity is the priority.

Geometry engineered for predictable turning performance

The triangular plate with a 60° included angle and 0.4 mm corner radius offers a balance between edge strength and fine detail, while the 11° relief angle reduces rubbing and cutting forces during engagement. The single‑sided chipbreaker is tuned for finishing cuts, promoting controlled chip flow and minimising vibration in stable setups. These geometric features make the insert particularly effective for finishing passes on external and internal turning where dimensional accuracy and surface finish are critical.

Material choice and machining behaviour explained

Made from cemented carbide substrate with an uncoated cermet specification, the grade emphasises edge sharpness and low cutting resistance rather than heavy roughing removal. This results in lower cutting forces and reduced heat generation at the cutting edge during finishing operations. For operators less familiar with cermet, it is a hard, wear‑resistant material that retains a keen edge—ideal for producing fine finishes but best used at modest feeds and depths of cut to avoid chipping under interrupted cuts.

System compatibility and practical mounting details

The insert is ISO‑standard and its compatibility with a holder depends on form, relief angle, tolerance class, fastening style, size and thickness. It is supplied in a triangle form with a central hole (cylindrical hole with a single‑sided countersink 40°–60°) for secure clamping in a matching external holder or boring bar. Typical system components include an ISO turning holder, a clamping pad or set, and replacement screws; correct matching of those parts ensures repeatable seating and concentricity for stable finishing results.

FAQ

What materials is this insert intended for?
The TPGT110204 NS9530 Tungaloy insert is optimised as a finishing grade for steel, delivering excellent surface quality during continuous cuts and small depths of cut.

Is the insert coated?
No, this insert uses an uncoated cermet grade (NS9530), chosen to maintain a sharp cutting edge and to improve surface finish in light finishing operations.

How is the insert mounted in a holder?
The insert uses a central hole with a cylindrical bore and a single‑side countersink; it is clamped in a matching ISO holder using the appropriate pad and screw to ensure correct seating and stability.

What is the corner radius and where is it beneficial?
The insert has a 0.4 mm corner radius, which balances edge strength with the ability to produce fine surface finishes, making it suitable for precision external and internal finishing passes.

Can this insert be used for roughing?
This grade is a finishing specification and performs best at small depths of cut and continuous feeds; for heavy material removal or interrupted cuts, a more robust roughing grade is recommended.
