Generally, the precautions for safe boring, drilling, counterboring and thread cutting apply. The following points, however, should always be emphasized:
- All tools must be in good condition and used only for the purpose for which they were made.- All workpieces must be securely held in position for drilling, boring or thread cutting. Excessive holding pressure may damage the work.
- Select tools of the right size for tightening or loosening bolts, nuts and screws. Tools of the wrong size tend to damage the workpiece and may slip off causing injuries.
- Make sure that large parts cannot drop to the ground when the bolts and nuts or screws are removed.
- It is regarded as good craftsmanship to store all tools properly and individual components always together with their counterparts.
