Klein Tools was founded in Chicago, Illinois, by German immigrant Mathias Klein in 1857. Klein developed and made a pair of side cutting pliers for a telegraph repairman. The company grew quickly as it began to make tools for telegraph, telephone, and electrical companies and their employees.
Today, Klein Tools continues to manufacture hand tools, specializing in electrical and telecommunications tools. The company manufactures nearly 4,000 different types of hand tools and tool bags. The company is still privately owned, with Thomas Klein as current CEO.
Klein Tool has its own drop forging plant in Moran, Kansas, as well as a distribution center in Cedar Rapids, Iowa. The company moved its headquarters in 2006 to Lincolnshire, Illinois.
I purchased a adjustable hole saw at the home depot to put in some 6in can lights in my kitchen.I was not happy with the tool performance,I only got to the third hole(dry wall) the guide drill broke and the cutter blades were dull.The allen wrench broke in my hand when I tried to adjust the blades from 7in to 6in.I have a lot of kline tools this tool should not carry the kline name.One good thing the dust collector worked great,what should I do with your tool.Finished the project with a 6in hole saw.
