Bosch is recalling about 20,000 hammer drills. The models have a grounding system and trigger switch that could cause ground wire abrasion and/or ground connector failure posing a shock hazard. In addition, the switch trigger could become stuck in the "on" position posing an injury hazard to the user.
Bosch 1/2 inch 2-Speed Hammer Drill with model number HD19-2, HD19-2D, HD19-2L and 1/2 inch 2-Speed Hammer Drills with model number HD 21-2 are included in this recall. "BOSCH" is printed in red lettering on the side of the drills.

The drills, made in Switzerland, were sold at home improvement, hardware and major retailers nationwide and various distributors from September 2009 through August 2010 for between about $140 and $220.
Consumers should immediately stop using the hammer drill and return hammer drill to Robert Bosch Tool Corporation for repair.
