TPGH 080204 NS9530 turning insert for Turning — Tungaloy

TPGH 080204 NS9530 is an ISO-format turning insert designed for finishing operations on steel, combining a sharp edge geometry with ISO compatibility for secure clamping and consistent surface quality

• Triangle insert, size 08, 60° included angle
• Uncoated cermet finishing grade NS9530
• Sharp edge for low cutting forces and fine finish
• Central hole with cylindrical seat and countersink

Dependable finishing with a cermet cutting edge

The insert is made from an uncoated cermet material formulated as the finishing grade NS9530, which focuses on delivering a sharp cutting edge and low cutting forces. This composition reduces chatter and improves surface integrity during light cuts, making it well suited for applications where a high surface finish is required. For customers new to cermets: cermet combines ceramic hardness with metallic toughness, offering a balance of wear resistance and edge stability that benefits finishing passes in steel.

ISO geometry that simplifies holder selection and set-up

Produced as an ISO turning insert, the item follows standard dimensions so compatibility with clamping systems is governed by form, relief angle, tolerance class, fastening and thickness. The insert has an 11° relief angle, a 2.38 mm thickness and a 0.4 mm corner radius, which together determine the contact geometry with the toolholder and the resulting cutting forces. Specifying these values when selecting a matching outside holder or boring bar ensures repeatable positioning and reliable clamping, shortening set-up time and reducing trial cuts.

Predictable machining for continuous and fine finishing cuts

The single-sided chipbreaker and the uncoated cermet grade are optimised for continuous cuts and small depths of cut, producing consistent chip form and minimizing rework. That predictability translates into predictable cycle times and lower scrap rates in finishing operations. Where dimensional stability and surface quality are priorities, the insert supports a controlled process that favours fewer follow-on operations and steadier productivity on production runs.

Application scope and system components explained

The insert is intended for external and internal turning on steel in finishing-mode applications. It is supplied as part of an ISO-system consisting of the insert, a compatible external holder or boring bar, a mounting pad/clamping set and replacement screws; the insert’s with hole and cylindrical seat plus single-sided countersink (70°–90°) provides secure mechanical location for repeated indexing. For workshops seeking a simple upgrade path, matching the plate geometry and thickness to the existing tooling system delivers a fast route to improved surface quality without major tooling changes.
