The Pramet ISO A25T-DTFNL 16 D.25mm left-hand boring bar is a high-precision tool specifically designed for lathes. It enables efficient and precise machining of materials through the use of triangular negative indexable cutting inserts. With an inner circle diameter of 9.525 mm and a thickness of 4.76 mm, this boring bar is ideal for applications such as internal deburring, internal taper turning, and shoulder-less turning. The left-hand design is particularly suitable for 90° longitudinal turning and provides additional flexibility due to its stepped shank construction. Made from robust steel and equipped with a coolant channel, it ensures optimal cooling during the machining process. With a diameter of 25 mm and a length of 300 mm, it is suitable for a variety of machining tasks, offering high stability and durability.

• Double clamping construction for secure hold of the indexable cutting inserts
• Left-hand design for precise 90° longitudinal turning
• Robust steel construction with coolant channel for improved cooling
• Suitable for internal deburring and internal taper turning
• Optimal functional width of 17 mm and functional height of 11.5 mm.
