TPGT 16T302 NS9530 indexable turning insert — finishing grade for turning — Tungaloy

A TPGT16T302 NS9530 indexable insert engineered for precision finishing in turning applications, offering a sharp cermet edge and low cutting forces for continuous cuts.

• Precision finishing insert NS9530 for steel
• Sharp cermet cutting edge, low cutting forces
• ISO triangular form TPGT 16T302, 60° included angle
• Cylindrical hole with single-sided countersink

Optimised finishing performance that reduces rework

The uncoated NS9530 cermet grade is designed as a precision finishing option for machining steel, delivering a consistently sharp cutting edge and low cutting forces. These characteristics translate into a superior surface finish on continuous cuts and when taking small depths of cut, reducing the need for subsequent grinding or polishing. By focusing on edge integrity rather than heavy material removal, the insert supports predictable part quality and minimises thermal and mechanical loading at the tool edge, which benefits cycle-time stability.

Predictable seating and compatibility for quick integration

The insert follows ISO norms for triangular turning plates, listed as ISO TPGT 16T302, so compatibility with standard external holders and boring bars is defined by form, 11° clearance, tolerance class, fastening, size and 3.97 mm thickness. This clear geometric definition enables straightforward tool selection and repeatable clamping, which reduces setup time and supports consistent cutting conditions across batches. The design intention is to make retrofitting into existing tool systems quick and reliable.

Material choice that supports process stability

Constructed on a carbide substrate with an uncoated cermet cutting layer, the grade combines edge sharpness with wear resistance suitable for finishing operations. The material pairing provides good dimensional repeatability and helps maintain a stable cutting edge when machining steels under continuous feed conditions. For operations prioritising top quality surface integrity rather than heavy roughing, this material setup offers a dependable balance between performance and tool life.

Practical geometry and clamping features for steady machining

The insert’s 0.2 mm nose radius and 60° included angle produce fine profile control and controllable cutting forces for detailed features. The plate is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to ensure secure clamping and correct seat orientation in the holder. At a plate size of 16 mm and a thickness of 3.97 mm, the component provides sufficient rigidity for finishing while remaining compatible with a wide range of ISO-compliant clamping systems for turning and internal turning operations.
