Combining a sharp, uncoated cermet NS9530 grade with ISO compatibility and a fine 0.4 mm corner radius delivers consistently high surface finish and low cutting forces for finishing turns; order the insert via Metav Werkzeuge or consult our specialists for application advice.

WNMG080404-TSF NS9530 ISO turning insert for finishing — Tungaloy

WNMG080404-TSF NS9530 is an ISO-format trigon turning insert designed for finishing operations on steel, offering a sharp cutting edge and precise, repeatable surface quality.

• ISO WNMG trigon insert, 80° approach angle
• Uncoated cermet NS9530 finishing grade
• 0.4 mm corner radius for superior surface
• Cylindrical hole, 4.76 mm plate thickness

Achieve finer surfaces with a dedicated finishing grade

The WNMG080404-TSF is optimised as a finishing insert: its uncoated cermet NS9530 substrate provides a very sharp cutting edge that reduces cutting forces and minimises built-up edge formation. For customers aiming to improve cycle consistency, this means fewer reworks and a predictable part finish. The 0.4 mm corner radius is tuned to deliver tight surface tolerance and fine profile control during continuous cuts and small depths of cut. Where surface quality is the priority, the combination of cutting geometry and material grade offers measurable process benefits.

Simple integration into standard turning systems for reliable productivity

The insert follows the ISO WNMG format with a trigon plate form and an 80° approach angle, ensuring compatibility with common external holders and boring bars. The cylindrical hole and standard dimensions (plate size 08, 4.76 mm plate thickness) enable secure clamping and repeatable positioning, which shortens tool changeover time and reduces set-up variation. These mechanical features translate into a more stable machining process and predictable tool life when paired with a matching TSF chipbreaker and holder tolerance class.

Practical guidance for machining steel with this finishing insert

This grade is primarily intended for turning of steel under continuous cutting conditions and low material removal rates. Use the TSF chipbreaker and conservative depth-of-cut settings to exploit the low cutting forces and achieve superior surface finish. While the insert excels at finishing, it is not designed for heavy interrupted cuts; for such situations select a more robust geometry or a different grade. The geometrical and material choices here help to reduce thermal load on the edge, supporting consistent dimensional accuracy across batches.
