The final choice depends on holder style, contour, approach angle, required edge strength and whether the cut is external or internal.<\/p>\r\n        <\/details>\r\n        <details>\r\n          <summary>Should I use a positive or negative CBN turning insert?<\/summary>\r\n          <p>Negative inserts provide a strong body for stable turning, while positive inserts can reduce cutting force and improve access in profiling or boring.

The correct grade depends on workpiece hardness, impact level, insert geometry, edge preparation and the current failure mode.<\/p>\r\n        <\/details>\r\n        <details>\r\n          <summary>Can CBN turning inserts be used for internal turning?<\/summary>\r\n          <p>Yes.
