How to use a hole saw
Using a hole saw can come in extremely handy when you need to drill holes in countertops, worktops, desks or at the back of cabinets to allow for cables and cords to be pushed through. We needed to make a hole in a worktop to allow our battery chargers to sit on top, with the cords underneath close to the power outlet.
If you haven’t used a hole saw before, here are some easy DIY tips to keep in mind:
When using a hole saw to drill through hardwoods or board products such as supawood (MDF) only use a minimum 500W rated drill. Anything less than this and you stand the chance of burning out the motor.
Do not use a blunt hole saw. This will put undue strain on the drill motor and could cause damage.
Always hold the drill perpendicular to where you are drilling the hole.
Start off by placing the tip of the drill bit (if the hole saw is fitted with this) in the centre of the marked position. If you are using a hole saw that does not have an integral drill bit, mark the location for the hole to be drilled and position the hole saw within these marks.
Start off by drilling at slow-medium speed until the bit has started to bite into the surface of the board or hardwood. This is especially important if you are using a hole saw that does not have an integral drill bit, as it prevents the hole saw from spinning across the surface. You can increase to full speed once the saw has cut into the surface.
Use a screwdriver or the allen key in your hole saw kit to lever out the scrap wood from within the hole saw.
