A line of rotary tools that can overheat and melt are among this week's recalled consumer products. Other products being recalled include mowers with leaky gas tanks and defective bicycles. The model number and date codes are located on the name plate of the product, which is on the side opposite the Dremel logo. The tool's circuit board can overheat and melt the tool's enclosure. Additionally, some tools may lose their speed control changing to high speed in use, turn on by themselves, or may not turn off, posing a personal injury hazard. Call Robert Bosch Tool Corp.
