What is a Bradawl?
A bradawl is a tool used in woodworking to create pilot holes for screws and nails.
What is a pilot hole?
A pilot hole is a smaller hole created before the required size hole is drilled, or to allow a screw to be driven in without the need for pre-drilling.
Pilot holes are beneficial because they:
Prevent Splintering and Splitting
Improve the Accuracy of the Hole Location and Execution
Make it easier to Drill a Hole, or put in a Screw or Nail, than trying to do it on an Unmarked Hard Surface
A bradawl is a hand tool, slightly resembling a screwdriver, but is much smaller. It consists of a handle, shank and chisel-shaped point.
Although, technically, the tip of a bradawl is shaped like a chisel, there are two other shapes of tip which can be considered bradawls: tapered round and tapered square.
These are, respectively, round point awls and birdcage awls. The word ‘bradawl’ can therefore be used generically to describe all woodworking awls.
