Rhombic (C) 80° Turning Inserts

Rhombic (C) 80° Turning Inserts

Providing the best balance of cutting-edge strength and operational versatility of all the insert shapes, these rhombic inserts have an 80° point angle and are a good choice for a wide range of longitudinal turning applications. With a cutting edge that is stronger than a trigon insert but less strong than a square insert, they are recommended for facing, roughing, light roughing, and semi-finishing applications.

Insert shapes are available with a range of point angles. In general, inserts with a large point angle have a stronger cutting edge but produce more vibration and require more machine power than inserts with a small point angle. Inserts with a small point angle are more versatile, provide better accessibility for detailed cutting, produce less vibration, and require less machine power than inserts with a large point angle, but they have a weaker cutting edge and may be more prone to heat damage.

Inserts are available with a negative or positive basic shape. Negative inserts have a 0° clearance angle. They provide good edge strength and are recommended for external turning and heavy cutting applications. Double-sided negative inserts offer twice as many cutting edges as positive inserts, but single-sided negative inserts provide the best stability in heavy roughing applications. Positive inserts have a clearance angle that is greater than 0° and are a good choice for internal turning applications and external turning applications on slender workpieces. Positive inserts are single sided and produce lower cutting forces than negative inserts.
