The ISO A25R-STFCR 16 D.25mm boring bar from Pramet is a precise tool specifically designed for lathes. It enables efficient internal taper turning and longitudinal turning, both with and without a shoulder. With a diameter of 25 mm and a length of 200 mm, it features a robust steel construction equipped with a coolant channel to regulate machining temperatures. The screw clamping ensures a secure attachment of the triangular positive indexable inserts, which have an inner circle diameter of 9.525 mm. This boring bar is designed for right-hand rotation and is ideal for applications requiring a tilt angle of -3 degrees. Its thoughtful design and the use of high-quality materials make it an indispensable tool for precise turning operations.
