DNMG 43 Boring Head for Anti-Vibration Boring Bars, 40 mm Dia., Right Hand

93° lead. Fits anti-vibration bars with a 40 mm (1.575") coupling: every bar 40 mm and larger, 2" included. Above 40 mm the coupling on the bar is off-centre, so the insert still reaches past the bar diameter. Insert on a shim under a top clamp. Minimum bore on a 2" bar: 2.362" (60 mm). Insert sold separately.
