The ISO S20S-SDUCL 11 D.20mm left-hand boring bar from Pramet is a precise tool specifically designed for lathes. It enables effective internal taper turning as well as copy turning in various directions. With a screw clamping mechanism for securing 55° rhombus positive indexable cutting inserts, it offers a reliable and stable hold. The left-hand design is ideal for longitudinal turning with a reduced shank. The boring bar has a diameter of 20 mm and a length of 250 mm, making it a versatile tool for various applications. Made from steel without coolant channel drilling, it is robust and durable, ensuring high efficiency during machining. The technical features, such as a -5 degree inclination angle and a 0 degree orthogonal cutting angle, contribute to optimal performance.

• Screw clamping for secure holding of indexable cutting inserts
