The drill bit packages are not properly labeled with precautionary information on proper use and operation. These and other manufacturers' 13-inch bits can bend when run at a high speed without being in contact with a work surface, resulting in loss of control of the drill and possible lacerations. The safety label should read: "! WARNING Read, understand and comply with tool manual before use. Wear eye protection. Max operating speed 600 RPM. At higher speeds the bit is likely to bend if allowed to rotate freely without contacting the work. Start drilling at low RPM and with bit tip in contact with work. To avoid bit bowing - Apply pressure only in direct line with bit and do not apply excessive pressure. Bits can bind, causing breakage or loss of control. Do not use in hammer drills or in drill press."
