The drill press is one of the most frequently used machine tools in every workshop. It can be used to drill holes in a wide variety of materials (plastics, wood, various metals).


2General security principles

In principle, only people who have been instructed in their work are allowed to work on the drill press. Otherwise there is a risk that the operating person will be injured through ignorance or that machines or products will be destroyed. The following protective measures and behaviors are necessary on drill presses:

  • Machines may only be used as intended. This means: the employees are only allowed to use and operate these in accordance with the instructions from temporary employment agencies and customer companies.
  • The drill press must be checked to ensure that it is safe to operate every time it is used, e.g. B. external damage, loose fastenings, abnormal noises when idling.
  • Before switching on, the drill (the tool) and the drill chuck (the tool holder) must be checked for proper condition.
  • If machines are defective or do not work as expected, they must not be put into operation. In the event of danger, the machine must be switched off immediately. The supervisor in the customer's company must be notified so that the fault can be remedied. Employees are only allowed to rectify malfunctions if they have been specially trained to do this by the customer. In all other cases, only the specialists on site are allowed to rectify the fault.
  • Workpieces must never be held by hand. Jigs must be used.
  • The tool and workpiece may only be changed when the machine is at a standstill.
  • Shavings must never be removed by hand, cleaning wool or a cloth, a hand broom is suitable. Blowing off with compressed air is not permitted, as the chips are only distributed at the workplace and drilling oil or cooling lubricant are distributed as an aerosol in the breathing air. There is also a significant amount of noise pollution.
