With their centre points and sharp cutting spurs, brad point bits have been specifically designed to drill accurate, neat holes in wood. They have a centre point so the bot does not “walk”. The relatively flat cutters and the wings give you an almost flat bottom, smooth hole with little tear out.
As brad points are smaller than the centre points of spade bits and the guide screws of auger bits and expansive bits, they can drill deeper into a workpiece without breaking the surface of the reverse side. This could be useful if you’re making a partial hole for a dowel joint while building your own furniture.
