What is a spade bit used for?
Spade bits are used to bore holes through wood quickly.
As they leave a rough hole, they are most often used to drill in areas that will later be covered, or that are not generally visible.
A good example of this is that electricians and plumbers use them to bore through timber if they need to insert wires or pipes.
While best suited to drilling softwoods, spade bits can also be used on hardwood, chipboard, fibreboard (such as MDF), plasterboard (used in walls), acrylic and plastic-laminated wood.
They can be used in drills, for general use, or impact drivers, if drilling holes in tree stumps or thick, tough wood.
