Bosch has recalled about 91,000 of their 1380 Slim 4-1/2″ angle grinders, which I remember writing about when they first came out. Another 18,000 are being recalled in Canada.
The problem? According to the recall notice, the grinder can overheat when being used, leading to melting of the brush covers, exposing the end of motor brushes to users, posing a burn hazard.
There were 4 reports of complaints, and 0 reported injuries.
The recall affects 1380 Slim grinders built between March 2015 through November 2015, with date codes 502 through 511.
If your tool is included in the recall, stop using it and contact Bosch for a free repair kit.
