Not cars but Cordless Hammer drills. I've been using a cheapo 12V cordless hammer drill for quite some time now but the charge goes fast these days and now the chuck area is making funny sounds like it's about to give up. Was in B&Q getting some new hinges for the back gate and thought I'd grab a new drill. I'd noticed a nice 18V Hitachi DV18DCL2 with x2 Li-Ion batteries etc. Was very tempted but checked out reviews online with my phone and I read that it was a little short on oomph - perhaps it's max torque wasn't as high as the other 18V drills. There was also a Bosch PSB 18 li-2 which was about the same price, has a neat LED working light but also has a depth gauge attached - really handy and would save me using masking tape around the drill bit when drilling holes for raw plugs. I checked out the reviews and it got high ratings. But I was torn. My parents had a Hitachi television which lasted 25 years and I've always rated them highly. But I also read that their stuff can be made in China and not Japan! I don't have a huge problem about where something is made, so long as the quality control is in place but then Bosch are pretty well known for making good tools. Here's my problem, I bought the Bosch but I haven't broken the seal yet because I had a look at some more reviews and have found out that there's a fundamental error apparently with the chuck loosening when you stop drilling/screwing. Something to do with the stop brake being too harsh? Has anyone got any experiences of Hitachi drills as I'm tempted to go back and exchange. - - - Updated - - - On further investigation it would seem that people are tightening up to and sometimes only including one click with the Bosch, which means it's not fully tightened and will come loose especially when hammer drilling. It would seem you have to tighten until it stops clicking. Phew! The Hitachi has got some great Youtube demos, looks like a good product also.
