Drills / Impact Drivers

Workshop Studio (Room G23)
Level 02 - Machine Safety


The cordless drills and impact drivers are power tools that deliver a strong, rotational and downward force to an object. They come with a range of ‘bits’ which attach onto the head of the drill and perform various functions such as boring holes in various materials or fastening various materials together with the use of screws or other fasteners.

Health and Safety

  • The cordless drill and impact driver are both power tools that have the potential to cause serious injury if used incorrectly. Always exercise extreme caution when using the equipment. NEVER touch the drill bits or other moving parts during use. These components can easily damage fingers and other body parts.
  • Do not wear loose articles of clothing and or jewelry when operating the cordless drill/ impact driver.
  • Do not try to remove jammed pieces while machine is still running.
  • Do not attempt to cut round or uneven objects.
  • Please see workshop staff if there are any issues with the machines operation. Please do not attempt to make any adjustments without prior approval.

Operation Instructions

  • Prepare workspace: Ensure that the workspace is clean and free of mess and debris. Secure the material that needs to be drilled/fixed in a vice or clamp.
  • Set up drill/driver: Check that the tool is in good working order before use. Insert the drill bit into the chuck and tighten it using the chuck. If you’re using a chuck key, make sure you take the key out before starting the drill. Check that the drill is not in reverse and that the torque settings are correct for your application.
  • Drill material: Push the drill bit into the surface of the material. Start up the drill and push down firmly. While you’re drilling, pull the drill back periodically to clear the waste material from the hole and drill bit. Keep the drill bit turning until you withdraw it from the hole.
  • Shut down and Remove material: When finished, withdraw the drill/driver from the material. Remove the bit, turn off the equipment and place them both back to their previous location. Remove the material and clean the workspace by placing any waste in the bin.

Workmanship Considerations

  • When drilling large holes or through metal objects it is best to centre-punch or drill a small indentation into the surface first, so that the tip of the drill bit doesn’t skid off the mark when it starts to turn.
  • The torque (or rotational force) can be adjusted on the drill/impact driver. In general, use slower speeds for hard materials.
  • Before drilling make sure that the bit is not in reverse. It sounds silly but it is a common mistake. Trying to drill in reverse just creates friction and smoke and won’t get you anywhere.
  • On deep holes, pay constant attention to the angle you’re holding the drill at, so you don’t start to change the direction of the hole while you’re drilling.
