About Rhombic (D) 55° Turning Inserts
Well suited for applications with limited machine power, these rhombic inserts have a 55° point angle and provide good accessibility for profiling in external and internal turning applications. They are recommended for light roughing, semi-finishing, finishing, and longitudinal turning 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.
These turning inserts are the first choice for machining steel.
