Note: The above figures are average and only applicable when drilling is performed on a machine with adequate power and rigidity together with the necessary coolant flow and pressure.

CAUTION – On through hole operations a disc is produced on exit. With a rotating work piece this can be projected with considerable velocity. Care must be taken to provide adequate guarding.
