History
The definitive origin of the first hammer drill is a matter of discussion, although if you look at "hammer drills" and "rotary hammers" as separate categories, the origins are clear. Hilti had the first "electro-pneumatic" rotary hammer on the market in 1967 (the Hilti TE 17) and the Milwaukee Electric Tool Corporation states that in 1935, it was selling a lightweight 1/4-inch electric hammer drill (cam-action) .

Famous quotes containing the word history:
“I believe that history might be, and ought to be, taught in a new fashion so as to make the meaning of it as a process of evolution intelligible to the young.”
—Thomas Henry Huxley (1825–95)
“Every generation rewrites the past. In easy times history is more or less of an ornamental art, but in times of danger we are driven to the written record by a pressing need to find answers to the riddles of today.... In times of change and danger when there is a quicksand of fear under men’s reasoning, a sense of continuity with generations gone before can stretch like a lifeline across the scary present and get us past that idiot delusion of the exceptional Now that blocks good thinking.”
—John Dos Passos (1896–1970)
“If you look at history you’ll find that no state has been so plagued by its rulers as when power has fallen into the hands of some dabbler in philosophy or literary addict.”
—Desiderius Erasmus (c. 1466–1536)
