A disposable drilling and milling cutter (10) for use with an NC or CNC machine tool and configured to be fed in a spiral manner includes a shank (11), a chip removing groove (12) at one of a plurality of offset positions at one end of the shank (11), a blade seat (13) at a distal end of the chip removing groove (12), and a disposable blade (20) locked to the blade seat (13). The disposable blade (20) has a cutting edge (23) at each of its upper and lower ends, and at least one cutting edge (23) has an irregular height and a notch (24). The wavy structural design of the disposable blade (20) enables the disposable drilling and milling cutter (10) to drill and mill in a sectioned manner, to break the drilling/milling chips automatically, and to perform intermittent processing.
