I always thought Hitachi had superior engineering/quality. No More
28 July 2014
Summary: Hitachi screwed up royally with thread pitch and collet bore. Other brand collets won't fit by about .001". Thus a bunch of other cutters etc., can't be used. So much for standardization. I always thought Hitachi had superior engineering/quality. No More!
Summary: I love Hitachi tools but this is junk. This is my second one that has done the same thing. The shaft separates from the motor so it just spins free. No abuse. I use it to trim plastic with a spiral bit, nothing heavy duty.
Batteries stopped charging after less than 1 year of light use.

Summary: The drill works great when the batteries work. After less than a year I cannot get the batteries to charge. Thinking it may have been the charger that is not working, I bought a new one. Same problem. So frustrating! I don't abuse my stuff and have only used it for fairly light work.
