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:
“What has history to do with me? Mine is the first and only world! I want to report how I find the world. What others have told me about the world is a very small and incidental part of my experience. I have to judge the world, to measure things.”
—Ludwig Wittgenstein (1889–1951)
“The greatest honor history can bestow is that of peacemaker.”
—Richard M. Nixon (1913–1995)
“The history of all Magazines shows plainly that those which have attained celebrity were indebted for it to articles similar in natureto Berenice—although, I grant you, far superior in style and execution. I say similar in nature. You ask me in what does this nature consist? In the ludicrous heightened into the grotesque: the fearful coloured into the horrible: the witty exaggerated into the burlesque: the singular wrought out into the strange and mystical.”
—Edgar Allan Poe (1809–1849)
