My first two ideas would be either the switch or the brushes. Sometimes the dust from drilling concrete will get into the brush holders and cause them to bind so the brush no longer contacts the armature.
Hope this helps!

Hi all,
working on a building a porch and had to drill a bunch of 1/2" holes into concrete. A friend who was helping got the drill bit stuck on rebar a couple of times and now the chuck keeps slipping in both hammer and normal drill mode (I can barely drill through a 2x4 with a 5/8th bit at this point). :(
I can actually stop the chuck from rotating by gripping it with my hand - motor keeps on running, but chuck is stopped.
Bought a bulldog extreme last weekend to get the job finished (I think it's the 11255 model) and the drilling went very well on the remaining ~ 70 holes.
Anyways, I was wondering if I can get the 1199 drill fixed as it is otherwise a great tool (guess it was undersized for the 1/2" holes)? From the parts diagram I can't quite tell what parts are the clutch/transmission - would guess one of those are the problem. I'll see if I can get it opened up this weekend and check if I can see any worn/stripped parts, but any help/suggestions would be appreciated....

The chuck is damaged on my Bosch 1199VSR and I want to replace it. Can anyone tell me how to remove the chuck and install a replacement? I'd like to do it myself rather than pay a shop. Thanks....

My chuck don't want to open completely. I've noticed that a new chunk would cost around 35$. Is it easy to install, what are the steps... Thanks alot...
