Tips for Using a Drill

The following steps will show you how to use a drill.

  • Use the correct size drill bit required for the screw or bolt being inserted.     TIP:  Drill a pilot hole first with a small bit.   This prevents a larger bit from moving when you start drilling.
  • Inserting a screw – choose a drill bit slightly smaller in circumference than the screw being inserted.  The reason for this is so the screw has material to grab as it is inserted.
  • Inserting a bolt – use a drill bit the same size as the bolt.
  • Hold the drill in your right hand if right-handed (left hand if left-handed)
  • With the left hand, open the Chuck enough so you can insert the round smooth end of the drill bit 1 inch (25mm) in between the chuck clamps.
  • Check the bit sits evenly between the clamps otherwise the bit will wobble when the drill is turned on.
  • Use the drill’s forward switch to tighten the drill bit into the chuck opening; reverse switch to loosen the drill bit in the chuck opening
  • Tighten the chuck by hand as far as you can so the drill bit sits inside the chuck without moving.
  • To finish tightening if you are using a:
  • Continue to hold the chuck while at the same time pressing the trigger switch until you feel the chuck go tight.
  • If the drill bit is not tight enough inside the chuck it will slip while drilling is in progress.
  • Repeat this step until it is tight.

Drill with a Chuck Key – after tightening the chuck as far you can by hand, take the chuck key insert it into the teeth at the side of the chuck and keep turning the chuck clockwise until you cannot turn it any further.

  • The bit should now be held tight inside the drill.Chuckless Drill – while keeping a firm grip around the chuck, press the forward switch on the drill.

How to Use a Drill

Once the drill bit is in place it is time to start drilling.

  • Check the variable speed is turned up (higher number) for general drilling.
  • Use clamps to fix your work material to a work bench or other surface to stop the material moving.
  • Working at waist level gives you better control over the tool being used.Use a small drill bit to provide a pilot hole, then move up in drill size to the desired finished size.
  • HOT TIP:  If a very fine edge is required on the surface use masking tape over the area being drilled as this help protect the edges of the finished hole size.
  • Hold the drill in a straight vertical line over the drill hole.
  • This is necessary to avoid the hole being drilled off-centre, or at an angle.Once the pilot hole is drilled, change your drill bit until the correct size bit is selected for the task at end.


Using a Drill to Insert a Screw

  • If using your drill to insert a screw adjust the variable speed control of the drill to a LOW SPEED.
  • The reason for this is to prevent the head of the screw or bolt from being stripped.
  • If stripped, you will have difficulty getting the screw in or out!
