Bosch announced the recall of approximately 20,000 hammer drills. According to the CPSC “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 could become stuck in the on position posing an injury hazard to the user.” So far no one’s reported any actual incidents.
Affected drills are the 1/2″ 2-speed variety with model numbers HD19-2, HD19-2D, HD19-2L, and HD 21-2. They were sold between September 2009 and August 2010. If you own one of these, you should immediately stop using the drill and return it to Bosch directly for repair. You can contact Bosch toll-free at 866-244-2110 between 7 a.m. and 7 p.m. Monday through Friday.
