RD Inserts

RD inserts (round turning inserts) are indexable cutting inserts used on CNC lathes and conventional turning setups for profiling, radius turning, and general contouring. They are selected when you need a stable cutting geometry, consistent surface finish, and predictable tool life across materials such as steel, stainless steel, cast iron, and various alloys.

This collection includes RD-- style inserts in multiple grades and coatings (e.g., PVD/CVD), with options suited for roughing or finishing depending on depth of cut and wear resistance requirements. You’ll find chipbreaker geometries and nose radius choices that help control chip flow, reduce vibration, and maintain a steady cut, with dependable solutions from Yg for demanding production environments.

RD inserts are widely used by machinists, manufacturing engineers, and process/QC teams in job shops and industrial production for repeatable turning performance in component manufacturing, maintenance work, and high-mix machining applications.
