歷史[編輯]

A wooden drill handle and other carpentry tools found on board the 16th century carrack Mary Rose.

最早期嘅鑽叫「弓鑽」(Bow drill),源自古印加文明古埃及。直到19世紀,摩打發明咗之後。由奧地利人Arthur James Arnot同埋William Blanch Brain將摩打套用喺鑽裏面,變成電鑽嘅雛型[1]

1889年澳洲墨爾本,Wilhelm Fein[2] invented the portable electric drill in 1895。1917年, 德國人Black & Decker patented a trigger-like switch mounted on a pistol-grip handle.[3]
