An auger attachment is one of the best-value add-ons you can buy. Fence lines, pergolas, shade sails, sheds and tree planting all go dramatically faster.

Choosing an auger

Set out and drill

  1. Set a string line along the fence and mark each post position.
  2. Position the machine so the auger hangs vertically over the mark.
  3. Start slowly to stop the bit wandering, then increase speed.
  4. Lift regularly to clear spoil from the hole.
  5. Check plumb and depth as you go.
  6. Move to the next hole keeping the machine on the same side of the line.

Before you dig: lodge a free enquiry with Before You Dig Australia (byda.com.au) and locate underground services. See Before You Dig in WA.

Perth tips

  • In loose sand, holes can collapse — set posts soon after drilling.
  • On limestone, use a rock bit or break the cap first.
  • In Hills gravel and clay, drill when the ground isn't rock-hard in summer.
