Word Origin & History

drill  (1)
1611 (n.), 1649 (v.), from Du. dril, drille "a hole, instrument for boring holes," from drillen "to bore (a hole), turn around, whirl," from P.Gmc. *threljanan. Sense of "to instruct in military exercise" is 1622 (also in Du. drillen and in the Dan. and Ger. cognates), probably from the notion of troops "turning" in maneuvers. Ext. sense of "the agreed-upon procedure" is from 1940.
