Key Features Of Metabo HPT NR90AES1
Does Hitachi make Metabo?
All right! When Hitachi changed his name to Metabo, it's obvious we'll raise the question, "Does Hitachi still produce framing nailers or other power tools?"
Metabo was a brand of the renowned power tools manufacturer company, the Metabowerke GmbH, headquarters in Nürtingen, Germany, and founded in the 1920s. Later on 1st March 2016, Metabo was acquired by Hitachi Koki, part of Hitachi Group. However, in March 2017, Hitachi Group sold Hitachi Koki through a tendering process to HK Holdings Co., Ltd., an entity of the investment firm KKR.
After that transition, on 17th October 2018, Hitachi power tools renamed to Metabo HPT. Currently, Metabo manufacturing its power tools in two factories in Nürtingen and Shanghai. Now it connected with 23 distribution companies and over 100 importers to spread out its products worldwide.
The real reality, then, is that Metabo HPT is just another Hitachi name, nothing else. You will find the same devices which have the same quality, the same pledge, and the same guarantee policy. You will also note they use the same batteries. Hitachi MultiVolt batteries are also interchangeable with Metabo HPT MultiVolt devices and Hitachi 18V batteries, and vice-versa.
So, we'll find the same packaging and color scheme that goes with the label, and which helps us to conclude that it's just a name change, nothing more.
