Hitachi invented the sliding compound miter saw. I remember when that 8" saw first showed up at my local tool store at the end of the 80's. It was stunning. Prior to that, no SLIDING compound miter saw had existed. We all used radial saws for that kind of work.
That being said, Hitachi just recently (as in a couple of months ago) sold their entire tool division to the same private equity group that bankrupted Toys R Us and Nabisco. This investment group "uses other peoples money" in highly leveraged buyout manipulations to acquire right and title to well known brands, eviscerating their assets, and then bankrupting out of the debt ridden carcass that remains, since the interest on the money they borrowed to buy the company exceeds the revenue the company is able to earn, especially after the cream of the brand was siphoned off the top.
By September of this year, the name "Hitachi" on power tools will no longer exist. The private equity group also recently bought the Metabo brand, and will rename all Hitachi tools as Metabo HPT. Based on the past performance of this private equity group (KKR), this move does not bode well for either brand.
I would have recommended Hitachi tools when Hitachi Tools was still owned by Hitachi, but now that Hitachi Tools is owned by KKR, I don't see a long term future for that brand, or the successor brand Metabo HPT. The leveraged buyout will increase their debt, and quality will be thrifted out of production to service that debt. Then patents will be sold off to enrich the investors, and engineering will be whittled down with lay offs to lower costs and service the debt. With no new innovative engineering, and poorer quality to reduce costs, people will stop buying the product, which will reduce revenue. After 10 years or so, with all the good corporate assets and real estate sold off to enrich the investors before impending bankruptcy, yet another Nabisco and Toys R Us will be in the news. Another brand bites the dust.
