1-1/4" Dia. Anti-Vibration Boring Bar, 7xD Overhang

1.250" diameter steel body with an internal damper, 8.750" effective reach (7xD). The damper absorbs the chatter that limits a plain bar, so the tool holds size at overhangs where a solid bar cannot cut. Through-coolant to the head. The cutting head is ordered separately and sets the minimum bore and the insert.
