How to use your Holesaw:

In an ideal world your piece of work should be clamped firmly to a bench to allow for slow controlled drilling. Of course sometimes thats just not possible, so if youre drilling in situ or at an awkward angle try the following:

Make a template from a piece of timber or waste material, locate this over the area where you want to drill your hole and use it as a guide to start the hole. Once youve got into the surface by 1mm to 2mm you can remove the guide and continue to drill in a controlled manner.

Start your hole diagonally, make a round trace and then hold drill straight.
