Cutting Tool Usage Safety Information Essential Safety Instructions Tool Usage Hazards In use, cutting tools may create sharp edges, vibrations, high temperatures and forces not only within the tool itself but also the work piece and waste produced. This can cause fragmentation of the tool and/or work piece due to excess stress or impact damage. Avoiding Injury When working with, or in the vicinity of cutting tools, all personnel should wear appropriate protective equipment at all times. Machine guards should be in place at all times.
