2.0 out of 5 stars Great hammerdrill except for one crucial design flaw, July 11, 2002

This review is from: Bosch 3670-04 14.4 Volt Cordless 1/2-Inch Hammer Drill (Tools & Home Improvement)

I was at first very happy with this hammerdrill. It's well built and comes with a case & two batteries. It also has a little clip on the handle to hold a screwdriver bit - brilliant. But when I started to drill into concrete the problems began. It drilled the holes as well as the Milwaukee I had borrowed from a friend, but apparently it has a design flaw that allows concrete dust to get inside and cause the speed control mechanism to get stuck. So when I tried to switch between the two speed settings, I wasn't able to push the switch "all the way" in either direction. That meant the chuck couldn't "get in gear" which means the motor turns but the chuck doesn't. So now the drill is totally useless. It's really too bad because I know Bosch makes great tools...

1.0 out of 5 stars review of 3850 drill, July 25, 2002

This review is from: Bosch 3670-04 14.4 Volt Cordless 1/2-Inch Hammer Drill (Tools & Home Improvement)

Sorry that this is not a review of this drill but a spot on Bosch's good name. I have a 3850 18 volt drill that has had low use in 2 years and both batteries are shot. I wrote to Bosch about this and they returned my message thanking me for my interest in Bosch tools. I do not think that was what I wanted to hear. This is the 3 rd Bosch battery drill I have owned and first that is NO GOOD! I have a 9.6 that the orginal batteries lasted about 10 years and it is now on second set that will out perform the 18 V by about 3 to one. I had a 7.2 V that outlasted the availabilty of new batteries. It was a great tool that got loads of use. I have several other Bosch tools but this piece of junk just might end my buying any more of these tools at all. Take hede when considering their tools.
