Talk:Rotary hammer

History
This article says that Hilti had the first rotary hammer drill (electro pneumatic) on the market in 1967. But Hammer drill says that Bosch had them already in 1932 on the market. Which is correct? 91.96.30.223 (talk) 19:46, 7 May 2023 (UTC)


 * BTW the german version of this article mentions both Bosch in 1932 and Hilti in 1967, which means this article is wrong. The german version does not have any references either, therefore I am not deleting the section from this article for now. (And BTW German language provides a very clear differentiation between “hammer” and “hammer”, therefore I think the german article did not mess up anything.) 91.96.30.223 (talk) 20:12, 7 May 2023 (UTC)
