Drill bits have cemented carbide buttons. Cemented carbide is made up of tungsten carbide and cobalt. Grinding buttons can produce dust and fumes containing dangerous substances that can be inhaled or swallowed, or which can come in contact with the skin or eyes. Do not breathe the dust. Wear protective gloves, protective clothing and eye protection. In case of inadequate venti-lation,wear respiratory protection. In particular, avoid dry grinding
ASSEMBLY OF BITS
