Grinding wheels are made of natural or synthetic abrasive minerals bonded together in a matrix to form a wheel. While such tools may be familiar to those with home workshops, the general public may not be aware of them because most have been developed and used by the manufacturing industry.
One of the most common metalworking tools is the grinder. Grinders are used in almost all garages, shops and jobsites, and can be purchased by anyone, almost anywhere. Grinders produce wheel speeds of 9,000 to 14,000 revolutions per minute (RPM), which expose the operator to serious hazards. Damaged or old grinding wheels can explode at these high speeds, producing flying fragments. They also produce excessive noise and flying particles.
