• Hole tolerance D+.014/-.002 in average conditions applied. It can be higher or lower according to machine and tooling conditions • For eccenter sleeves, see page 147 •
For user guide and cutting conditions, see pages 146-158
(1) The hole diameter can be enlarged by shifting the drill center along the lathe X-axis, or by using eccentric sleeves in drill rotating applications
(2) Master insert identification
